A Christmas party turns deadly when a scandalous affair, suspicion of treason, and a woman scorned lead to murder in this 1920s-style whodunit.
London 1928. For Sir Edmund Ferrier, the past year has been one of hard-won triumphs. Recently appointed a cabinet minister, Sir Edmund confidently expects to be elected prime minister one day. But when his ex-lover, Mrs. Pulver, is found dead in his study, Sir Edmund soon finds his career and his life in danger—not least from his spiteful and enigmatic wife.
Sir Edmund's secretary, Mr. Quayle, knows there's more to Mrs. Pulver's murder than meets the eye. Vital documents have gone missing from the ministry, and Mr. Quayle believes that Sir Edmund and Mrs. Pulver were involved. Unfortunately, the ministry has a different suspect in mind—Mr. Quayle.
Desperate to prove his innocence, Mr. Quayle sets out to catch the killer and find the missing documents. But he soon discovers that treason isn't the only skeleton hiding in Sir Edmund's cupboard in this classic Agatha-Christie-style whodunit.
