Louisiana Longshot by Jana Deleon

It was a hell of a long shot.... CIA assassin Fortune Redding is about to undertake her most difficult mission ever—in Sinful, Louisiana. With a leak at the CIA and a price placed on her head by one of the world's largest arms dealers, Fortune has to go off-grid, but she never expected to be this far out of her element. Posing as a former beauty queen turned librarian in a small bayou town seems worse than death to Fortune, but she's determined to fly below the radar until her boss finds the leak and puts the arms dealer out of play. Unfortunately, she hasn't even unpacked a suitcase before her newly inherited dog digs up a human bone in her backyard. Thrust into the middle of a bayou murder mystery, Fortune teams up with a couple of seemingly sweet old ladies whose looks completely belie their hold on the little town. To top things off, the handsome local deputy is asking her too many questions. If she's not careful, this investigation might blow her cover and get her killed. Armed with her considerable skills and a group of elderly ladies the locals dub The Geritol Mafia, Fortune has no choice but to solve the murder before it's too late.
