Marcia Muller and Bill Pronzini, both well known mystery writers, have written this interesting detective novel. The two main characters live in San Francisco in the 1890′s and own a detective agency. Sabina Carpenter and John Quincannon have been hired to find a pickpocket and a burglar. They are a team but work separately since they both have their own way of doing things. During the investigations they meet a man who claims to be Sherlock Holmes although he supposedly died in a waterfall accident in Europe. John takes an instant dislike in him but it’s mostly about competition. I liked this setting in San Francisco and it wasn’t a long complicated story so it was easy to follow. Hope they do another one.
