Query: Cardboard characters

I usually like Tami Hoag's books, she is a story teller with a surprising twist. The twist was there this time also. However,the characters were way too predictable. They all seemed on the dark side, even the "heroes." Surely there has got to be a non-divorced person in this world. Not in her book. Well, unless you are the guy who kills people because they're in the way. Then you can be single and never married.The bad guys had no redemptive features -- too cartoon-like.And the unnecessarily bad language was a turn-off. Surely even in cop land not every one uses the f... word in every sentence.The plot was somewhat interesting but felt undeveloped, kind of like the characters.Of course tastes differ. I like a bit more psychological depth with my murders than Tami Hoag offers in this story. Maybe next time.
