Use the past to alter the future... Visitors are dying to get out of the Emerald City and rebellious Seattle detective, Nate Cliffton, must team again with his time-traveling friend, John Carpenter, to face an elusive serial killer who targets tourists. John sees only the killer's profile during one flashback, so Nate resorts to the old-fashioned way of catching criminals, but he keeps coming up short. Pushing John to try again, Nate faces one of his biggest fears-having a friend in danger because of his actions. Throw in the complications of a three-pronged government response, a new hook-up, and a new partner and Nate's tapped-out. For John it's a matter of staying alive. For Nate it's hunting down a murderer before another out-of-towner is floating in Puget Sound.
