A Plague of Secrets — John T. Lescroart

Bay Beans West, the coffee shop at the corner of Haight and Ashbury, is always crowded with customers, and manager Dylan Vogler has done very well for himself. Maybe too well. After he's found dead behind the shop -- still wearing a backpack full of Baggies stuffed with pot -- his annual ninety-thousand-dollar salary raises some eyebrows, and casts suspicion on the shop's real business and its owner, Maya Townshend. Married, wealthy, devoutly Catholic, and the niece of the city's mayor, Maya doesn't seem like your typical drug dealer -- let alone killer -- but the gun that killed Vogler was hers. And as Dismas Hardy is discovering, Maya has a lot of secrets. He's just not sure whether they include murder. . . .
