Nice. I've seen the movie a bunch of times and have wanted to read the book for a while now. Was the end the same as in the movie, basically leaving it up for you to decide whether or not he's killing all the people?
The ending is pretty similar but the book is way more extreme in its violence and depravity.
HeavyRob's post reminded me that it's time to get some Clive Barker books again. Clive Barker was the only man ever to fly under my gaydar b/c I was so amazed by his mind. I loved Books of Blood, the Canyon (I think that's what it's called, I've had it for years and haven't looked at it recently) Everville, etc.
Coldheart Canyon I think is the one you mean. That is good but his best IMO are The Great and Secret Show and Weaveworld.
Clive Barker is gay? you live and and learn.
