When the cops see the murdered corpse of Ph.D. candidate Lexie Madison, found near Glenskehy, Ireland, they agree how remarkably identical the victim is to one of them, Detective Cassie Maddox (see IN THE WOODS). Since they could have been identical twins, in spite of the danger Cassie agrees to pretend to be Lexie in order to trick her killer into exposing him or herself.
Cassie as Lexie movies into Whitethorn House, the mansion the victim shared with four other post graduate students (Daniel, Justin, Rafe and Abby); she informs them that she was fortunate to have survived the assault. As Cassie investigates each of her flatmates, she finds she likes each of them because they are so different in personality. However, inside the mansion the quintet begin to argue, but Cassie wonders if the threat to her as Lexie might be from the village.
This brilliant psychological suspense police procedural is a strong tale because the four surviving roommates and the cop masquerading as the fifth seem genuine especially inside of Whitethorn House. The relationships between the quintet enhances the tension as Cassie and the readers wonder who of these nice flatmates is the killer, if any; and when will the next attempt occur.
