The Stealing of Murial McKay: It was a case of mistaken identity. The kidnappers following the lady in the Rolls-Royce had confused Muriel McKay with someone else. When her husband returned home that night he found an open handbag, its contents scattered on the stairway, a telephone on the floor, and the house deserted. Strange ransom notes and frightening phone calls served only to deepen the mystery. The search for Mrs. McKay's whereabouts became an agnozing struggle, a race against time to save her from the mysterious figure who identified himself only as M3. Neill Cream, Poisoner: Dr. Neill Cream was a courtly gentleman, fashionably dreassed. There was, to be sure, a curious look in his eye; and he seemed to spend more time prowling London by night than practicing medicine by day. But, as distinguished historian Elizabeth Jenkins recounts, it was not until far too many unsuspecting young women had died quite horribly that Scotland Yard setout to discover just what the mysterious "doctor" was up to. The case of Stanley Setty: It was a dimembered corpse wrapped in a parcel that the duck hunter discovered floating in one of the shallow salt flats along the Essex coast. Upon examining it, the Yard's forensic experts found a number of stab wounds and announced that it had fallen from a great height, possibly a plane. But who was it? Swiftly, methodically, the sleuths of Scotland Yard pieced together a fantastic and hair-raising story. The Wembley Job: It took just ninety seconds for England's slipperiest robbers to make off with a third of a million dollars from a Wembley bank. It was done with sledgehammers and shotguns; and the identity of the culprits was well concealed. Still, in just three months a Scotland Yard robbery squad had broken the case wide open. The gang known as the Frighteners had met their match. The Portland Spy Case: Hidden in their house was an incredible array of espionage devices: a high-powered radio station, a false-bottomed cigarette lighter, and concealed microdot messages. All this and more belonged to Peter and Helen Kroger, Russian trained spies. Their mission -- to obtain, highly secret weapons information from Britain's Portland Naval Base. Here is the exciting story of how Scotland Yard tracked the Krogers down and gathered evidence for an airtight case against one of Britain's most notorious spy rings. Doctor Crippen's Diary: Dr. Crippen said his wife, Cora, had gone to America. Later he reported that she had died there. But, curiously, his secretary, Ethel Le Neve, was seen wearing Mrs. Crippen's jewelry. What had really happened to Cora Crippen? An investigation led to a grisly discovery in the basement of the Crippen home, but by then both secretary and doctor were nowhere to be found. It took Inspector Drew of the Yard to unravel one of the most fiendish crimes of the century. The Shepherd's Bush Case: In an act of almost unprecedented violence, three policemen were gunned down in broad daylight just outside of London. The men of Shepherd's Bush Police Station were determined at all costs to find whoever was responsible for the cold-blooded murders. Shortly, what was to become one of the longest and most horrowing manhunts in the history of Scotland Yard was under way. The Siege of Sidney Street: Sidney Street was suddenly ablaze with a cross fire of bullets as detectives and police attempted the capture of a gang of anarchists who had been cornered in a house there. Crowds came from miles around, and even Britain's Home Secretary, young Winston Churchill, arrived on the scene, along with the Scots Guards. Then came the fire brigade, who had rushed there to extinguish the fire burning out of control in the East End tenement where the desperate men were holed up.
