Judgement and Wrath (Joe Hunter)

the long version

"'Some call me a vigilante. I think I've just got problems to fix.' Joe Hunter doesn't like bullies. So his latest job - saving a young woman from her bully boyfriend - is a no-brainer. Hunter's only worry is that the man who hired him is looking for more than protection for his daughter. One thing Hunter has never been, and never will be, is a killer-for-hire. As it turns out, the vengeful father isn't the only one who wants the boyfriend dead. Soon Hunter is face-to-face with a contract killer who takes his work very seriously. Dantalion has a talent for killing and keeps a list of his victims in a book chained to his waist. Each victim is numbered. And the body count is about to start rising..."--Publisher.
