In the second of Tana French's Dublin Murder Squad series, which can be read in any order, detective Cassie Maddux is pulled off her current beat and sent to investigate a murder. When she arrives at the scene, she finds the victim looks just like her, and—even more creepy—she was using an alias that Cassie used in a previous case. The victim was a student, and her boss talks her into trying to crack the case by impersonating her, explaining to her friends that she survived the attempted murder. The victim lived with four other students in a strangely intimate, isolated setting, and as Cassie gets to know them, liking them almost in spite of herself, her boundaries—and loyalties—begin to blur. A taut psychological thriller that keeps you guessing till the end.
