Tool & Die — Sarah Graves

When her new housekeeper starts receiving death threats, Jake Tiptree and her best friend Ellie White promise to check out the most likely culprit: the woman's ex-husband. Jim Diamond is an ex-con and a deadbeat, but he doesn't have a history of violence...until Jake and Ellie find a corpse in his run-down apartment.

Now, with her terrified housekeeper on a cleaning rampage, a moose in her kitchen, a rebellious son, and a troublesome ex of her own, Jake is already at wit's end. So when the killer strikes again, clearly Jake and Ellie have gotten mixed up in a master plan of greed, deception, and death. And their place in the murderous scheme? A pair of private rooms--six feet under!
