Professional bridge player and writer Joseph Bowne Elwell was shot in 1920 while inside his locked Manhattan home. The case inspired the 1926 mystery novel The Benson Murder Case. According to a report in The New York Times, March 10 and 11, 1929, Isidore Fink, of 4 East 132nd Street, New York City, was in his Fifth Avenue laundry on the night of March 9, 1929, with the windows closed and door of the room bolted. A neighbor heard screams and the sound of blows, but not shots, and called the police, who were unable to get in. A young boy was lifted through the transom and was able to unbolt the door. The police found Fink dead with two bullet wounds in his chest and one in his left wrist. No money had been taken, and no weapon was found at the scene. It was theorised that the murderer may have climbed the outside of the building and fired through the transom, but a powder burn on Fink's wrist indicated that he had been shot at close range. Interviewed some years later, Police Commissioner Mulrooney called the Fink murder an "insoluble mystery". On May 16, 1937, Laetitia Toureaux was found stabbed to death in an otherwise empty first-class compartment of the Paris Métro. The subway train had left the terminus, Porte de Charenton, at 6:27 p.m. and had arrived at the next station, Porte Dorée, at 6:28 p.m. Witnesses did not see anyone else enter or leave the compartment where Mlle. Toureaux's body was found. The murderer had one minute and twenty seconds at their disposal. Neither the murderer nor the method of their escape was ever discovered. In 2010, the uninjured dead body of Gareth Williams, an employee of the Secret Intelligence Service (MI6), was found in a bag that had been zipped up and padlocked from the outside, with a key inside. There was no forensic evidence of anyone else's involvement. Two escapologists investigated whether he could somehow have locked himself inside the bag. After 400 unsuccessful attempts one of them would still not completely rule out the possibility.
