I'd forgotten how much I enjoyed these comic-caper Dortmunder novels over 30 years ago, and I'd certainly forgotten the plot of this one. Here practically the entire population of New York City, every small time crook, every mafioso, every FBI agent, and every NYC cop is looking for the poor schmuck who inadvertently stole an internationally famous ruby. Enter Dortmunder. How he manages to keep his identity secret, evade capture, and get rid of the gem is truly astonishing, but it helps that the novel was written before mobile phones were much more than an engineer's dream. In spite of all the bad guys present, the real villain of this piece is the blow-hard chief of police, Francis X. Mologna (pronounced Maloney). I laughed out loud at that one. At one point two mysterious dark cars full of men in black follow him home, box him in, the men first threaten him and his family, and then force him to take $20,000 in cash, with a promise of $60,000 more after he has done their dirty work. The next morning he promptly turns the money over to the FBI, deeply offended that anyone might think that the top cop of the great city of New York would even consider accepting bribes. From strangers.
