Lionel Crabb

Lionel “Buster” Crabb served in World War II in the Royal Navy. Later, in 1956, he was recruited by MI6 to help them do reconnaissance of a Soviet cruiser. He suited up in his scuba gear and went to work right away. However, once he dived into the water, he disappeared completely. Some time later, a body floated ashore without its head or hands, wearing scuba gear. They tried to determine if it was Crabb, but no one, not even his family, could identify the body. Many theories have floated around about his disappearance, including that the Soviets got him and killed him or threw him in the gulag.
