The small room was filled with a shocked silence. The audience were gathered in the back room of an inn for the 1925 annual general meeting of the Cairn Gorm Club in the Scottish Highlands to listen to tales of new hikes and climbs in the Cairngorm Mountains, but they were not expecting to hear a story like this. The speaker was Professor John Norman Colley, an experienced mountaineer and man of science. Everyone listened intently, some open-mouthed, as Colley spoke of his memories from a fateful day decades earlier while hiking on Ben McDewi. A thick mist had suddenly enveloped Colley. In it, he experienced something so terrifying that he hadn't spoken a word about it for 35 years. Colley described how after reaching the large stone cairn that marked the mountain summit, he was cautiously navigating his way back down the path when the mist ascended. Swirling thickly, by turns it revealed, then swallowed up, the dark grey, almost monster-like shapes of rocky outcrops. With no visual cues to guide him other than the thin line of rocky path beneath his feet and his compass bearing, Collie proceeded slowly. Taking a wrong turn could send him towards one of the precipitous cliffs that flanked the peak. The crunching of his boots on the trail was the only sound to be heard. Then, Collie said, he began to think he could hear something besides his own booted feet. For every few steps he took, he thought that he heard another set of feet making that crunching sound behind him, almost like an eerie echo. Except that someone, or something, was taking only one giant stride for every three or four of his own. Summoning the most rational part of his scientist's mind, Colley told himself it was nonsense, he'd just imagined it. but to be sure he then stopped and listened. Then he heard the sound once again, then again. The timing suggested a very large stride which paused as if waiting for Collie's next move. Trying to pull himself together, Professor Collie resumed walking and once more came that eerie crunch, crunch, crunch coming from behind him. This time, all reasoning left the normally rational Collie. Seized with terror as he described it to his audience, he started to run, staggering and stumbling over the rocky ground as fast as he could. For almost five miles, he continued on, bumping and ricocheting between the boulders that flanked the trail, until he finally reached the comparative safety of the Rothy-Mircus forest below. Concluding his story, Professor Colley told his stunned audience to make of it what they would. All he could say was that there was something very strange about the top of Ben McDewey, something that had so frightened him that he would never go back there again. You're listening to Unexplained, and I'm Richard McLean Smith. Today, if you go hiking in the Scottish Highlands, you're unlikely to have the mountain paths and peaks to yourself, even in the dead of winter. Walking the mountains, along with winter sports like ice climbing and skiing, are popular pastimes for locals and tourists alike, but it wasn't always this way. In the late 1800s, walking Scotland's mountains for fun was mostly a pastime for a small group of wealthy and educated Victorian gentlemen, Men like Sir Hugh Munro, who combined his delight in cataloguing nature, including his collections of butterflies and fossils, with his newfound hobby of ascending Scottish peaks. He drew up a list of all 282 Scottish mountains with an elevation of 3,000 feet or more. First published as Munro's Tables in the Journal of the Scottish Mountaineering Club in 1891, The list gave rise to a new sport, reaching the top of all of them, known as Monroe Bagging. Sadly, Sir Hugh never quite managed to summit all 202 himself, dying during a flu epidemic at the end of World War I, with only three peaks left unclimbed. John Norman Colley was born in 1859, near the city of Manchester, in the north of England, but he had strong Scottish roots. His father was from Aberdeenshire in northeast Scotland, so the family moved back there when Collie was still a boy. Like Munro, Collie fell in love with the outdoors and Scotland's wild mountainous country. He would go on to become a professor of medicine, conducting pioneering work on the use of x-ray photography. But he always found time for hiking expeditions into the Scottish mountains, especially the Cullins of Skye, where he helped establish new routes, along with local mountain guide John McKenzie. In 1895, he was part of the first ever attempt on Nanga Parbat, a 24,000-foot high peak in the Himalayas. Collie was already an experienced and respected figure in Scottish mountaineering when he went walking in the Cairngorm Mountains in 1890. Back then, such ventures were much more of an expedition than the comparatively easy day trips of today. At the time, the Cairngorms were relatively remote, and in some places still relatively unexplored. Rail and good road links had not yet been built. You could often be out among the rocks and heather all day and not see another human soul. The Cairngorms consists of a high plateau reaching almost 4,000 feet above sea level, pierced here and there by domed summits, the eroded stumps of once much grander mountains. The highest of these is Ben McDewie. At 4,295 feet above sea level, it is the second highest peak in Britain, behind Ben Nevis on Scotland's northwest coast. In 2023, a story gripped the UK, evoking horror and disbelief. The nurse who should have been in charge of caring for tiny babies is now the most prolific child killer in modern British history. Everyone thought they knew how it ended. A verdict, a villain, a nurse named Lucy Letby. Lucy Letby has been found guilty. But what if we didn't get the whole story? The moment you look at the whole picture, the case collapses. I'm Amanda Knox, and in the new podcast, Doubt, the case of Lucy Letby, we follow the evidence and hear from the people that lived it to ask what really happened when the world decided who Lucy Letby was. No voicing of any skepticism or doubt It cause so much harm at every single level if the British establishment of this is wrong Listen to doubt the case of Lucy Letby on the iHeartRadio app Apple podcasts or wherever you get your podcasts.

I'm Menelik Lumumba. It's 1969. Malcolm X and Martin Luther King Jr. have both been assassinated, and Black America is at a breaking point. Rioting and protests broke out on an unprecedented scale. In Atlanta, Georgia, at Martin's alma mater, Morehouse College, the students had their own protest. It featured two prominent figures in Black history, Martin Luther King Sr. and a young student, Samuel L. Jackson. To be in what we really thought was a revolution, I mean, people would die. 1968, the murder of Dr. King, which traumatized everyone. The FBI had a role in the murder of a Black Panther leader in Chicago. This story is about protest. It echoes in today's world far more than it should. And it will blow your mind.

Welcome to Boys and Girls, the podcast where dating isn't dating. Arranged marriage is basically a reality show, except the contestants are strangers and your entire family is judging. You're sipping coffee with one maybe, grabbing dinner with another, and praying your karmic Ken or Barbie appears before your shelf life runs out. Trust me, I've been through this ancient and unshakable tradition. I jumped in, hoping to find love the right way. And instead, I found chaos, cringe and comedy. And now, I'm looking for healing. Boys and Girls dives into every twist and turn of the arranged marriage carousel. The meet awkward, the near misses, the heartbreak, and let's not forget all the jokes. Listen to Boys and Girls on the iHeartRadio app, Apple Podcasts, or wherever you get your podcasts. The landscape that surrounds Ben McDewie's summit is desolate and boulder-strewn. Scattered here and there are freestanding rocky outcrops. The arctic alpine vegetation is sparse. It's a place where, apart from the howl of the wind and patter of rain on the rocks, the occasional calls of birds like ptarmigan, snow buntings and red grouse are the only sounds. The weather can change rapidly, one moment benign, the next harsh. It's a landscape in which clouds descend or mists rise. The visibility can fall to just a few feet, making it easy to become disorientated and lost. Had the tale that Colley told the Cairn Gorm Club that evening in 1925 been told by another man, it might not have been believed. But with his status as an experienced mountaineer and rational man of science, the story made a great impression on those present that day and those who heard of it later. This was not a man to imagine phantoms or likely to panic on a summit. In time, the sinister being was given a name. M for Liam Moore in Scots Gaelic. In English, the big grey man of Ben McDewi. or simply, the Grey Man. And so, for over a century, something described as a presence or as a creature has been said to haunt the summit and surrounding passes of Ben McDewi. The Big Grey Man has joined a list of creatures, some of which have existed for centuries, in the legends and folk talk of mountain peoples around the world, like the Yeti from the Himalayas, Bigfoot from North America and the Yi Ren or Wild Man of China. Welsh mythology also has its own version of the being called Brennan Thalewid. In English, the Grey King. Described as a silent semi-corporeal figure who hides in the mountain mists preying on unsuspecting travellers, especially children. When Colley's account was reported in the local press, The professor soon discovered to his immense surprise that he wasn't the only one who'd been terrified on those very same slopes. One letter after another arrived through his door, detailing accounts from climbers who had previously been too afraid or too ashamed to share their experiences. Just like Collie, several confessed to similar feelings of terror caused by a being that they had sensed was with them on the mountain. Hugh Welsh was hiking to the summit with his brother in 1904, where throughout the day and night they heard footsteps that sounded to them as if someone was walking nearby through soaking wet gravel. Both men were utterly convinced that something was stalking them. Only in a few of the cases reported to John Colley did people report actually seeing something. Those who did claimed to glimpse a large dark shape looming towards them. Others described a very thin being, over 10 feet tall, with long arms and broad shoulders, either with dark skin and hair, or else an olive complexion, or covered with short brown hair. Occasionally, some said they'd seen an unusual-looking footprint, but more often, the apparent creature seemed to stay hidden in the mist. The reports dried up for a time until, after the onset of the Second World War, several more vivid reports of the spectre began to surface. From 1939 to 1945, Peter Densham was the leader of the Cairngorms Royal Air Force Rescue Team. One day, towards the end of his service, Densham was participating in a rescue exercise on Ben McDui. As he neared the summit, he heard what he described as strange noises on the mountainside, although at first he felt sure that they were merely caused by stone shifting. Then around dusk, as the light began to fade, a dense mist closed in on his location. Suddenly, Densham reported feeling a sensation of pressure increasing around his neck, followed by another crunch in the gravel to his left. Densham couldn't articulate what was happening in that moment. All he knew was that he had to leave immediately. Overcome by terror, he began running down the mountain, only to find that he was heading straight towards a precipitous ravine. As he later told his son, it was as if someone was deliberately pushing him in that direction. It was with no little effort that he found he had to force himself to correct course before continuing his way down the mountain safely. Some weeks later, Densham experienced an even eerier encounter. This time he was accompanied by a climbing partner Richard Frere. As the two men neared the mountain summit, once again the landscape became shrouded in a dense fog. The fog became so thick that the two men quickly lost sight of each other. As Densham steadily continued on his way, he heard the faint sound of Frere's voice and another voice talking to each other. Assuming his friend had bumped into another climber, Densham joined in the discussion from a distance. The conversation continued for a while until the other voice dropped out at which point Densham asked Frere who he'd been talking to but Frere was confused. The whole time he thought he was just talking to Densham. Three years later and Richard Frere was back on the mountain standing alone at one point he heard the eerie sound of what he took to be someone singing a single high-pitched note. On hearing Peter Densham and Richard Frere's stories, a mutual friend who wished to remain anonymous confessed that around that same time he had been camping on Ben McDewie one night when he suddenly awoke with an inescapable feeling of dread. He opened his tent and looked outside. There he saw a large figure with dark hair, standing silhouetted in front of the moon. In 1958, the naturalist and mountaineer Alexander Tunian published an article in the Scots magazine in which he described a solo climbing trip in the Cairngorms from 1943. One afternoon, he wrote, just as he reached the summit of Ben McDewey, A mist swirled up from a famous pass below, known as the Larig Groot. Tunian pulled on some extra layers as the weather conditions rapidly became dark and oppressive, and a fierce wind sprang up feathering and whistling among the boulders around him Then he heard a loud footstep pierce the mist Then another And another. Straining his eyes toward where the sound came from, Tunian claimed that a strange shape suddenly loomed up out of the mist. As he attempted to make out what exactly it was, the figure appeared to recede for a moment, only to emerge from the mist yet again, and this time to charge at the climber. Managing to keep his composure, Tunian whipped out a revolver and fired three times at the ghostly figure, but this failed to make it retreat. At this point, like several men before him, his nerves got the better of him and he turned and ran, not stopping for breath until he reached the valley of Glendary below. Toonion commented in his article that he'd never travelled that path so quickly before or since. He believed that what he'd seen was the big grey man. During the early 1920s, former president of the Moray Mountaineering Club, Tom Crowley, was descending from a peak to the west of Ben McDewey when a huge grey, mist-shrouded figure with pointed ears, long legs, and finger-like talons on its feet came into view. There's no record of whether Crowley turned and ran. Meanwhile, in his book A Hundred Strangest Unexplained Mysteries, writer Matt Lammy describes the experience of three men who claim to have come face to face with an eerie, dark, human-shaped figure in a forest in Aberdeenshire on the eastern side of the Cairngorms. They claimed to have seen a face looking at them from between tree branches, which was in their words, human but not human. One of the men claimed to have thrown a stone at it, causing it to disappear into the trees. A few weeks later, the same trio were driving in the area when the men alleged that the same bipedal creature suddenly appeared from out of the trees and pursued their car, running at up to 45 miles per hour. After some time, it eventually gave up and apparently stood in the middle of the road, just watching, as the car and its frightened occupants sped away. Despite the various reports, no photographs of the so-called Big Grey Man have ever been taken. Photographer John Rennie did take shots of a series of footprints measuring 19 inches long and 14 inches wide that he found in the Spey Valley below the mountain, believing them to be those of the creature. It was only later that he discovered they weren't footprints at all, but caused by a natural process that occurs when rainfall melts the snow. Some sceptics are of the firm belief that there is no Big Grey Man, and that he is instead a manifestation of a well-known mountain phenomenon. Born in 1770, James Hogg was a Scottish poet, novelist and essayist. In 1791, the author was walking on Ben McDui when he encountered what he described as a giant blackamoor, an archaic term for Muslims from North Africa and the Iberian Peninsula. At least 30 feet high, Hogg wrote that it had all the appearances of a giant, long-limbed grey silhouette of a man which seemed to stand against the backdrop of the clouds behind it. At first, the author was struck powerless with astonishment and terror, but his terror began to subside when he realized that the figure was aping his gestures. When Hogg raised his arm, the grey man raised his. When he held his leg to one side, the apparition did the same with the exact same timing. Took off its hat at the same moment he did. With a flash of relief and comprehension, Hogg realised that the grey man was just his own shadow. These days, this atmospheric phenomenon is well known to hikers and mountaineers. It's called a Brocken spectre, named after the Brocken peak in Germany's Harz Mountains, where, as on many Scottish peaks, it's a frequent occurrence. It's caused when a low-angled sun's rays filter through low cloud or fog to produce the shadow of a person which appears elongated, almost like something coming out of the mist on which it's projected. The giant, grey, humanoid shape is often surrounded by a rainbow-hued halo, giving it a ghostly, almost angelic appearance. Non-believers in the Big Grey Man have also pointed out, in relation to the strange sounds that some climates have heard, that the wind can make extraordinary sounds as it howls and whistles over exposed rocks, outcrops and boulders. One mountain on the eastern side of the Grampians, called Loch Nagar, is even named the Loch of the Outcry, or in Gaelic, Loch Nagara, due to the frequent moaning and howling of the wind among its rocks, while a pass to the south is called Balakun Skanya, or rocks that make noises. And yet, experienced mountaineers who've reported hearing the creature would almost certainly be familiar with just such a thing. And if the big grey man is merely an optical illusion, what of the alleged encounters that have happened after sunset? Not to mention the inexplicable sounds of footsteps and the sudden sense of panic that is said to accompany them. In 2023, a story gripped the UK, evoking horror and disbelief. The nurse who should have been in charge of caring for tiny babies is now the most prolific child killer in modern British history. Everyone thought they knew how it ended.

Physiologically, it's thought to be caused by the brain misinterpreting a survival safety signal to back up. instead sometimes leading to a desire to jump from a high place, which only intensifies the sudden onrush of anxiety. It can be induced by a lack of oxygen, stress and fatigue. The symptoms like the feeling of losing control of a situation dizziness or shallowness of breath can vary But a universal symptom is a sense of impending doom which can strike when you least expect it. Magazine editor Sarah Collins was alone on a chairlift at almost 4,000 feet above sea level while on holiday in the Canadian Rockies when the thought suddenly came into her head to jump. Surveying the magnificent array of mountain peaks around her, Collins was gripped by a sense of dread and the feeling she was about to lose control of her body. A former sufferer of obsessive-compulsive disorder, she'd successfully developed techniques for suppressing recurring intrusive thoughts and had considered herself cured. But on this occasion, she was experiencing a combination of jet lag and the sense of being in an unfamiliar environment. Now she became overwhelmed by a full-blown panic attack. Collins gripped tighter and tighter onto the metal bar in front of her, the only thing between her and the abyss below. For ten long minutes, she had the feeling that at any moment she might give in to the impulse to launch herself off the chair. Eventually, the calming voice of a mental health professional that she'd been treated by years ago came back to her. Collins described the antidote as being akin to allowing yourself to just float rather than thrash the water when you think you're about to drown. Gradually, she persuaded herself to relax her grip on the bar and lie back in the chair. She survived the ride. Could it be that mountaineers who have seen The Big Grey Man have often been suffering from mountain panic, experiencing symptoms recognised by psychologists as often brought on by a combination of isolation and exhaustion? Even experienced and well-trained adventurers can succumb to hallucinations under the combined assault of fatigue, low oxygen, the cold and a desolate landscape. There are many accounts of hill walkers and climbers experiencing the high place phenomenon across the British Isles in places as far afield as the Isle of Skye, the Grampian Highlands, and the mountains of England and Wales. Almost all accounts of the big grey man include a sense of being overtaken by feelings of dread, sometimes so much that some on Ben McDewie have reported being drawn towards the precipitous drop at a place called Lurcher's Crag, almost prepared to throw themselves over the edge, so intense is the feeling. And then, of course, there is infrasound. It has been known for some time that infrasound can affect human physiology and psychology. There have even been clinical experiments to test it. In 2004, at the School of Mechanical Science and Engineering at Huousong University in Wuhan, China, a study was carried out to monitor the changes of blood pressure, heart rate, and the subjective feelings of subjects exposed to infrasound. The study adopted two different infrasonic treatments based around the sound wave frequency of 2 Hz and 4 Hz. During the experiment, one group was exposed to infrasound of 2 Hz at a volume of 100 dB for 1 hour, while a second group was exposed to 4 Hz at a volume of 120 dB for 1 hour. Any noise with a frequency over 20 Hz, the lower limit of human hearing, was minimised to avoid any interference with the results. A blood pressure meter and cardio tachometer were used to measure any changes in the subject's blood pressure and heart rate. It was found that exposure to both frequencies of infrasound made the subjects feel headachy, fretful and tired. When exposed to 4 hertz over an hour, the blood pressure and heart rate of most participants rose. In natural settings, infrasound can be generated by the wind. You may remember, in Season 7, Episode 21, Wild is the Wind, We told the story of the Reverend James Pike and his wife Diane, who some suspect was driven mad by the wind while on a research trip in the Judean desert. Pike died in mysterious circumstances on the expedition. Wind-generated infrasound has been implicated in causing feelings of uneasiness, anxiety and paranormal sightings for some time, and mountains are frequently windy places. In 1998, in the Journal of the Society for Psychical Research, researcher Vic Tandy published a study showing how a 19 Hz standing airwave, just below the human ability to hear it, may under certain conditions create sensory phenomena in humans suggestive of a ghost. In the paper, titled The Ghost in the Machine, Tandy advised researchers of paranormal experiences to try and rule out this potential natural explanation for their investigations. All that being said, as recently as 2022, Scottish newspaper The Daily Record ran a story about a guest staying at Mar Lodge in the Cairngorms who'd left a post on a wildlife sighting board at a ranger's hut. Most posts on the board reported things like the sighting of adders or eagles or bemoaned the appearance of biting midges, but on the 27th of September, one spooked guest wrote something a little different. According to them, they had spotted a creepy grey silhouette standing at the summit of Ben McDui. Whether it was in fact a brocken spectre, just their mind playing tricks on them, or indeed a real living thing lurking in the mist, just like the mystery of M.
