This lighthearted comedy-thriller was written by Agatha Christie expressly for Margaret Lockwood.
The plot revolves around the moment when Clarissa discovers a dead body in her drawing-room and tries to dispose of it before her Foreign Office diplomat husband returns home with a government VIP guest in tow.
Equipped with an over-active imagination, Clarissa finds real life murder a little too hard to handle. Having persuaded her house guests to help her, it soon becomes apparent that the dead man was not unknown to everyone amongst them.
As the web of deceit starts to unravel, Clarissa pulls her friends into a desperate race to unveil the murderer and solve the mystery before the police discover the felony and arrest her as their prime suspect.
