The AgathasThe Agathas

Alice Ogilvie's disappearance last summer is the biggest scandal at Castle Cove High School--until her ex-boyfriend is accused of murdering his new girlfriend, and Alice must pair up with her tutor Iris Adams to clear his name by relying on the wisdom of Agatha Christie.
Last summer Alice Ogilvie's basketball-star boyfriend Steve dumped her... then she disappeared for five days. Where she went and what happened to her is the biggest mystery in Castle Cove, because she's not talking. Now, another one of Steve's girlfriends has vanished: Brooke Donovan, Alice's ex-best friend. And it doesn't look like Brooke will be coming back. Iris Adams, Alice's tutor, has her own reasons for wanting to disappear, but doesn't have the money or the means. The reward Brooke's grandmother is offering could change that. The police are convinced Steve is the culprit, but Alice and Iris set out to prove his innocence-- using the complete works of Agatha Christie as their guide. -- adapted from jacket
