Butch Karp has two cases where a particular cop appears to be the perpetrator. Marlene Ciampi's security company does a public offering of stock, and soon she's a millionaire. Their daughter Lucy is doing mission work with the homeless and soon she is at risk when Karp's 2 cases collide. I love the banter between Marlene & Butch - clever dialogue. I wish the female protagonists had more agency, though even Butch gets his life saved by a less than savory character.
