Detective Cassie Maddox is still trying to deal with the events of In the Woods. She is out of the Murder Squad and has started a relationship with fellow detective Sam O'Neill but is too badly shaken to commit to Sam or to her career. Then Sam is allocated a new case, that of a young woman stabbed to death just outside Dublin. He calls Cassie to the murder scene and she finds the victim is strangely familiar. In fact, she is Cassie's double. Not only that, but her ID says she is Lexie Madison the identity Cassie used, years ago, as an undercover detective. With no leads, no suspects and no clues, Cassie's old undercover boss spots the opportunity of a lifetime: to send Cassie undercover in the dead girl's place. She could pick up information the police would never hear and tempt the killer to finish the job. So Cassie moves into Whitethorn House, poses as a post-grad student, and prepares to enter Lexie's world.
This was my first Tana French book and I loved it. I was told I didn't need to start at book #1 in this series and they were right but now I want to go back and start at one and keep going. The characters were interesting and I thought the plot was original even though this would never happen in real life but it's fiction. I enjoy a good psychological thriller/murder mystery.
