New York City
When Lord and Lady Angkatell host a reunion at their country estate, the hostess mischievously invites Dr. John Cristow, a notorious womanizer, and his wife Gerda. The unexpected appearance of movie star Veronica Craye, his ex-mistress, gives the evening an interesting turn — as does the murder of the good doctor. Enter the local inspector, who must deduce his way through the thicket of motives, secret love triangles, surprise twists, and the usual suspects of a fun Agatha Christie thriller.
