Graham and Joan Bendix have apparently succeeded in making that eighth wonder of the modern world, a happy marriage. And into the middle of it there drops, like a clap of thunder, a box of chocolates. β©Joan is killed by a poisoned box of liqueur chocolates that cannot have been intended for her to eat. The police investigation rapidly reaches a dead end. Chief Inspector Moresby calls on Roger Sheringham and his Crimes Circle β six amateur but intrepid detectives β to consider the case. The evidence is laid before the Circle and the members take it in turn to offer a solution. Each is more convincing than the last, slowly filling in the pieces of the puzzle, until the dazzling conclusion. β©This edition includes an alternative ending by the Golden Age writer Christianna Brand, as well as a brand new solution devised by the crime novelist and Golden Age expert Martin Edwards, expertly evoking the original novel and adding an exciting new dimension. β©Anthony Berkeley was a pen name of Anthony Berkeley Cox (1893β1971), one of the most important figures in the history of British crime fiction. Many of his novels feature the amateur criminologist Roger Sheringham. As well as being the author of many classic detective stories, Berkeley was the founder of the prestigious Detection Club for the finest crime writers.
