One of my friends was describing a Dean Koontz book -- she didn't remember the title -- about two brothers (twins I believe) and one of them was evil and they might have been abused as kids...something she said about it intrigued me a bit and I was wondering if anyone knew what book it was .. does it ring a bell for anyone?
Oh, I've read this one too! Now what was it called? Why not use google search? Possibly: Mr Murder (although they're not exactly twins) <- this is the one I think it is The Bad Place <- this one is pretty twisted. And biologically inaccurate.
