Thief of Souls — J.G. Faherty

Perry Spellman didn't want to be a thief, he simply ended up that way to make back all the money he lost on a bad business investment. Only three houses, and then he can stop. Except it seems like someone is running a scam on him, trying to frighten him into turning himself in. Perry believes it is his old business partner, the one who took off with all his money. But soon he comes to find it is something much worse, something that won't leave him alone until he repents. Or dies.
