It's 1957, and the famed theater critic A. S. Crystal has come to the British seaside resort of Brighton with something other than the local production of A Shilling in the Meter on his mind. Sitting in the Brighton Royal Theater with Constable Twitten, Crystal intends to tell the detective the secret he knows about the still-unsolved Aldersgate Stick-Up case of 1945. And yet, just before Crystal names the criminal mastermind involved, he's shot dead in his seat.
