Sparkling Cyanide - Plot Summary

Plot Summary

One year ago on 2 November, seven people sat down to dinner at the restaurant "Luxembourg". One of them, Rosemary Barton, never got up. She was thought to have committed suicide due to post-flu depression. Her husband, George Barton, received anonymous letters saying that Rosemary did not kill herself but was murdered. George started to investigate and decided to reconstruct the dinner at the same restaurant, inviting the same people as well as an actress who looked like his late wife. The actress did not arrive and that night George died at the table — poisoned, like his wife, by cyanide in his glass.

His death would have been dismissed as suicide as well if not for the investigation by his friend Colonel Race. During the investigation it is revealed that the intended victim was Rosemary's younger sister Iris, whose glass was confused with that of George by a careless waiter. Due to a stipulation of her uncle's will, as Rosemary died childless her inherited fortune passed to her teenage sister when she died. If Iris had died at the table as intended, the money in turn would have passed to her aunt Mrs Drake. Mrs Drake is very much at the mercy of her lazy son Victor, who often threatens to commit suicide when he needs money from his mother. Colonel Race and Iris's suitor, Anthony Browne, discover that Victor had planned the murder together with his lover Ruth Lessing, who was also George's secretary.

The plan failed because when the group went to dance Iris dropped her bag and the waiter who retrieved it placed it a seat away from where she was before she went to dance. When the companions returned to the table, George sat at Iris's original place and drank the poisoned champagne. In order to confirm the suicidal nature of the death, Ruth had planted a pack of cyanide in Iris's bag and Victor had disguised himself as a waiter in order to poison the sparkling wine. When this failed, Ruth then attempted to run down Iris with a car. Eventually, Colonel Race, together with the police and Anthony Browne, unravel the truth and save Iris from Ruth, whose last attempt at killing Iris, i.e. knocking her unconscious and setting up a fake suicide by gassing scenario. The anonymous letters to George were sent by Ruth to convince him to re-stage the dinner at the Luxembourg so that Victor and Ruth could kill Iris.

Famous quotes containing the words plot and/or summary:

    The westward march has stopped, upon the final plains of the Pacific; and now the plot thickens ... with the change, the pause, the settlement, our people draw into closer groups, stand face to face, to know each other and be known.
    Woodrow Wilson (1856–1924)

    I have simplified my politics into an utter detestation of all existing governments; and, as it is the shortest and most agreeable and summary feeling imaginable, the first moment of an universal republic would convert me into an advocate for single and uncontradicted despotism. The fact is, riches are power, and poverty is slavery all over the earth, and one sort of establishment is no better, nor worse, for a people than another.
    George Gordon Noel Byron (1788–1824)
