Darkly Dreaming Dexter is the first novel I've read by Jeffry Lindsay, and it will surely not be the last. It's simply fascinating to follow along with the title character (a self-admitted monster who just so happens to be a forensics expert) both in his novels and in the series on Showtime that takes some surprising departures from the novels.
The actual plot is fairly straight forward, and even a bit dull. There's an ingenious serial killer on the loose in Miami and the police are helpless to stop him. That's really about it. But the character of Dexter elevates the basic police procedural into something new. He's someone who walks through life pretending to be a human being, all the while trying in vein to understand the motivations and behaviors of those around him. Oh and every now and then he'll go and cut someone into pieces. And just to warp things a tad more the novel has a bit of a humorous edge to it that makes the whole story even more disturbing.
