I Know What You Did Last Wednesday

by Anthony Horowitz

Part of Diamond Brothers

First published 2007

Nick Diamond dreads the school reunion invitation that arrives for him and his detective brother. The event takes place on an isolated Scottish island, far from any help. Nick feels something wrong from the start, and his instincts prove correct when he meets the other guests. One by one, the reunion attendees begin dying in increasingly strange and elaborate ways. Each death seems more impossible than the last. Nick must figure out who among them is the killer before he becomes the next victim. The remote location means no escape and no outside assistance. As the body count rises, Nick realizes that someone planned this reunion specifically to gather these particular people together. The deaths connect to something from the past that someone wants to settle permanently. Nick faces his most dangerous case yet, trapped on an island with a creative murderer who knows exactly what they're doing.
