"A mystery"--Jacket.

"Baton Rouge Police Detective Wallace Hartman has had better days. With her long-time partner and mentor on medical leave and a personal life in shambles, she's called to the scene of a particularly gruesome murder: the body of a known criminal has been found in a deserted warehouse, a snake sewn into his belly ... When federal agent Mason Cunningham arrives on the scene, Wallace expects a hostile takeover of the case. But when a scientist with ties to the victim goes missing from a government lab, she needs Mason's federal connections as much as he needs her local insight, and the two form an uneasy partnership"--,Provided by publisher.
