Against her better judgment, Lady Tressilian permits dashing Nevile Strange and his wife to come to her house party at the same time as his ex-wife, and sure enough, as soon as everyone arrives, the tensions are evident.
Lady Tressilian's house party is thrown into disarray by the death of her old friend Justice Treves. Meanwhile Nevile is feeling the strain of a house party with both his wife and his ex-wife in attendance.
Lady Tressilian is discovered murdered in her bed, leaving everyone in the house party very distressed. Inspector Leach leads the investigation.
Now Nevile is in the clear, suspicion has turned on Audrey for the murder of Lady Tressilian. But no-one can find her, and MacWhirter is convinced she's innocent.
