Monkeewrench - P. J. Tracy

Haunted by their pasts, Grace McBride and the crew of her software company, Monkeewrench, create a computer game in which a serial killer is always caught. But their game becomes a nightmare when someone begins duplicating the fictional murders in real life. People are dying for the new computer game by the software company Monkeewrench.

Literally. With Serial Killer Detective out in limited release, the real-life murders of a jogger and a young woman have already mimicked the first two scenarios in the game. But Grace McBride and her eccentric Monkeewrench partners are caught in a vise.

If they tell the Minneapolis police of the link between their game and the murders, they'll shine a spotlight on the past they thought they had erased-and the horror they thought they'd left behind. If they don't, eighteen more people will die...
