Lansdale, Joe R., 1951- Hap and Leonard series #13

"Minnie Polson is dead. Burned to a crisp in a fire so big and bad it had to be deliberate. The only thing worse is that Hap and Leonard could have prevented it. Maybe. Minnie had a feeling she was being targeted, shaken down by some shadowy force. However, when she'd solicited Hap & Leonard, all it took was one off color joke to turn her sour and she'd called them off the investigation. Wracked with a guilty conscience, the two PIs--along with Hap's fleet-footed wife, Brett--tuck in to the case. As they look closer, they dredge up troublesome facts: for one, Minnie's daughter, Alice, has recently vanished. She'd been hard up after her pet grooming business went under and was in line to collect a whopping insurance sum should anything happen to her mother. The same was due to Minnie's estranged husband, Al, whose kryptonite (beautiful, money-grubbing women) had left him with only a run-down mobile home. But did Minnie's foolish, cash-strapped family really have it in them to commit a crime this grisly? Or is there a larger, far more sinister scheme at work?"--Amazon
