The Spook Lights Affair -- the latest in the Carpenter and Quincannon historical mystery series from MWA Grandmasters Bill Pronzini and Marcia Muller. In 1895 San Francisco, young debutantes don’t commit suicide at festive parties, particularly not under the eye of Sabina Carpenter. But Virginia St. Ives evidently did, leaping from a foggy parapet in a shimmer of ghostly light. The seemingly impossible disappearance of her body creates an even more serious problem for the firm of Carpenter and Quincannon, Professional Detective Services. Sabina hadn’t wanted to take the assignment, but her partner John Quincannon insisted it would serve as entrée to the city’s ultra-rich and powerful. That means money, and Quincannon loves the almighty dollar.
