Jack Reacher races to solve the perfect crime in the fourth novel in Lee Child's New York Times bestselling series. Across the country, women are being murdered, victims of a disciplined and clever killer who leaves no trace evidence, no fatal wounds, no signs of struggle, and no clues to an apparent motive. They are, truly, perfect crimes. In fact, there's only one thing that links the victims. Each one of the women knew Jack Reacher--and it's got him running blind.
