Somebody broke into a collector's house and the world's most famous and biggest diamond was taken. Inspector Smithy interviewed three suspects after the burglary. He knew it was a one-man job.
The inspector also knew that each suspect told him one false and one true statement.
Slick Jim said: “It wasn’t me. And Burglar Bill didn’t do it.”
Burglar Bill said: “It wasn’t me. And it wasn’t Dodgy Dick.”
Dodgy Dick said: “I didn’t do it. And Slick Jim and Burglar Bill were at the races with me.”
The inspector knew immediately who the burglar was and arrested him.
Who did the inspector arrest?
