Primer and punishment

Whitney Whitaker and her cousin Buck are looking once again to rehab and resell a house, only this particular house is made of fiberglass, floats, and has been dubbed the Skinny Dipper. The charming and handsome Grant Hardisty lives on the cabin cruiser in the adjacent slip, but the cousins soon learn he's left a half dozen angry ex-wives in his wake and made enemies of all sorts of unsavory folks. Whitney and Buck are spraying primer on their houseboat when Grant's boat blows sky high with the man himself inside. Detective Collin Flynn has no shortage of suspects, but the waters become muddied when several of them confess to the crime. When anonymous threats are made against the cousins, Whitney must quickly determine who killed their neighbor at the lake, or she and Buck might also be sunk.
