Without Fail
Lee Child
 Reacher arrives in Atlantic City, New Jersey, after hitching a ride with a couple of aging musicians. He is accosted there by Mary Ellen Froelich, a beautiful secret service agent who managed to track him down. She has a special request for him: she consults him on how he could kill the Vice-President; countering those methods would help her considerably in her job: protecting the Vice-President. He accepts the challenge, and enlists old colleague Frances Neagley to help carry out the mission. Froelich asked Reacher's assistance on this matter because of suspicious and threatening letters which had been sent to the Vice-President but instead intercepted by his protective team. Together, they attempt to find the ones responsible.
