Mr. Murder by Dean Koontz

Martin Stillwater, or Marty, is quite sure he had a rather violent encounter with someone who looked and sounded like him. As if that isn't troubling enough, The Other even claims that Marty stole his life, his wife and his children. The police wouldn't believe Marty; with a doubt bordering close to skepticism, they entertain the thought that Martin Stillwater, mystery novel writer and recent People magazine feature story, is on a publicity-seeking spree. With nobody else to trust, Marty takes matters in his own hands to protect the family The Other is so bent on reclaiming.

It's a clone story, and while I'm not into the sci-fi genre when it comes to books, Mr. Murder is, surprisingly, a good read. It isn't more of the science and less of the suspense. In fact, apart from mentioning the reason for the eerie similarity between Marty and Alfie, nothing more of the science mumbo-jumbo is mentioned in the book. It's the thrill of the hide-and-seek that gets you hooked.
