Running Blind

Description for RUNNING BLIND by Lee Child:

Across the country women are being murdered, victims of an extraordinarily disciplined and clever killer who leaves no trace evidence, no fatal wounds, no signs of struggle, and no clues to an apparent motive.

Even the elite team of FBI agents assigned to the case is baffled by the ingenuity of these perfect crimes. But who's committing them? Why? And how? So far, there's only one connection: each victim knew Jack Reacher. And this time, even he's running blind.

This is #4 in A Jack Reacher Novel.
