On the Line — S.J. Rozan

P.I. Bill Smith is sent on a high stakes chase when an electronically modified voice on his cell phone informs him that Lydia Chin, his occasional partner, has been kidnapped. Now if Bill wants to keep Lydia alive, he'll have to play an elaborate game of the kidnapper's devising. The first move sends him to an abandoned building where Bill finds the corpse of a small Chinese woman dressed like Lydia and the building being rapidly surrounded by police. Now Bill is on the run from the cops and in the worst trouble of his very troubled life. With the help of Lydia's hacker cousin Linus, and Linus's cohort Trella, Bill has to not only stay one step ahead of the cops, he has to uncover the secret behind the kidnapper's identity and the reason he's come after Bill, if he's to reach Lydia before it's too late.
