Agatha Christie. Cianuro a colazione

Rosemary Barton takes one sip of champagne at her wedding anniversary dinner party and then suddenly collapses dead. "Cyanide poison", the doctor exclaims. Was it suicide or murder? Rosemary certainly had her fair share of enemies. Her husband George believes it to be murder and so he gathers together the same dinner guests and recreates the party, hoping to add a surprise guest to bring the killer out in the open. Unfortunately, poor George also gets a taste of poisoned champagne and ends up taking a trip to the morgue. It is then left to Rosemary's sister Iris and private investigator Tony Browne to solve the mystery.

The suave Anthony Andrew lends a lot of charm as the sleuth who is out to catch the poisoner, and of course romances Deborah Raffin at the same time. Sparkling Cyanide might not be set in England, and of course it plays more like a soap opera, but nevertheless very enjoyable, light, brisk and there's a sense of clarity and simplicity in the execution of the story and the mystery.
