1874: Booby-Trapped Inheritance
"When the father of the present Duke of Richmond died, he left his son a bank-note for $50,000, but it is in a casket, and the casket is so arranged that any person tampering with it would receive six pistol shots. As the secret of opening it without letting off the pistols has been lost, the contents of the casket are not likely to be squandered. There is French authority for saying that this story is strictly true."
