"D" is for Drunk — Sean Black; Rebecca Cantrell

Roll up your pant legs and bare your feet, there are barrels of grapes to crush in this hilarious fourth installment of the Malibu mystery series. Maloney Investigation's new client? An eccentric vineyard owner convinced his even more eccentric neighbor is siphoning off his precious water. But of course it's not as simple as that. Or as dignified. Sofia and Aidan soon find out these Merlot messiahs are turning water into wacky, plowing more than fields, and sowing more than grapes. But there's no putting the cork back in when the opposing vintner turns up naked and face down in a trough of sour grapes. Can Sofia and Aidan clear their client and unmask the killer? Or will they, too, perish in the Pinot Noir?
