Shoot to Thrill — P.J. Tracy

It begins with a floater.

When Minneapolis homicide cops Gino Rolseth and Leo Magozzi are called to a derelict stretch of the Mississippi River, they see the bride, facedown, dead in the water. And when the Monkeewrench crew-computer geeks who made a fortune on games, now assisting the cops with special anticrime soft-ware-are invited by the FBI to investigate a series of murder videos posted to the Web, it's not long before the group dis- covers the frightening link between the unlucky bride and the latest, most horrific use of the Internet yet. Using their skills to scour the Net to prevent more killings, the team must race against the clock . . . before it's too late.
