Velocity by Dean Koontz

The international bestseller Dean Koontz delivers a masterclass of storytelling suspense in this thriller. What would you do if a serial killer forced you to choose who he murders next?

On the windscreen of his SUV, Billy finds the first note.

It gives him a choice. If he takes the note to the police, an elderly woman will be killed. If he doesn’t approach the police, a schoolteacher will die. He thinks it’s a hoax. The schoolteacher is killed. Further notes taunt Billy’s conscience, forcing him to decide who lives and who dies. He must think the unthinkable, fast, in an accelerating nightmare.
