Clockwise counting 40/50: Anthony Berkeley - The Poisoned Chocolates Case (1929) One of the classic mysteries of a bygone era. A notorious upper class womanizer receives a sample box of liqueur chocolate addressed to him at his club. He doesn't like chocolate but a fellow club member who has lost a bet with his wife owes the same wife a box of chocolates. The gift box is transferred to the other club member who brings it home to his wife. After indulging in five or six pieces, each which have an unusually strong taste of alcohol and almond, the wife falls acutely ill and dies shortly thereafter. The police fails to get to the bottom of the case and labels the murder the act of a madman. A society of criminologists are conducting meetings on a regular basis and they decide to solve the case. The six members of the society conducts independent research and each presents his or her conclusions and a theory on 6 consecutive nights of meetings. This is a very technical puzzle and doesn't have any of the literary pretensions of Dickson Carr or Dorothy Sayers. Enjoyable as entertainment and skilfully narrated on a technical level but inferior to the true masters of the genre. I think.
