Poisoned Chocolates Case

Sir Eustace is a cad of the first water, with a specialty in other men's wives, and the list of people who might want to do him in could fill a London phone book. But which of them actually sent the chocolates with their nasty hidden payload? Scotland Yard is baffled. Enter the Crime Circle, a group of society intellectuals with a shared conviction in their ability to succeed where the police have failed. Eventually, each member will produce a tightly reasoned solution to the Case of the Poisoned Chocolates, but each of those solutions will identify a different murderer. First published in 1929, this is both a classic of the golden age of mystery fiction, and one of the great puzzle-mysteries of all time.
