Alice Ogilvie returned after disappearing for five days but refuses to explain where she went. When her former friend Brooke Donovan vanishes and is later presumed murdered, suspicion falls on the boy both girls dated. Alice doubts the police theory and joins forces with her tutor, Iris Adams, who needs the reward offered for information. Guided by Alice's knowledge of Agatha Christie, the two investigate Castle Cove's competing stories and secrets, placing themselves in danger as they try to identify Brooke's killer.
