After the shots were heard the body in the car was passed and re-passed dozens of times for the best part of three hours before a policeman finally found it. The reason for the disinterest was that this was poaching country where shots were always being fired, and because the vehicle was parked in a favourite spot for courting couples, where no one looked too closely at what was going on inside a car.

The victim, Samuel Wilson, a provision merchant, had been robbed of his day’s takings, collected on his rounds in Warsop, in the Sherwood Forest, Nottinghamshire, district. He was killed in the evening of Wednesday, September 24th, 1930, with a 12-bore double-barrel shotgun only 100 yards from where he was last seen by people who recognised him.

“Every opening ended in a blank wall,” remarked Chief Inspector James Berrett, of Scotland Yard. “There was nothing tangible – no clue that led anywhere.”
