Mosley introduces here PI Leonid McGill, a short, broad, and boxer-tough black fifty-something, who, after a back-story crisis, is trying to lighten the shade of his moral ambiguity, and is easy to root for. He has a few laughs tossing out character names like Norman Fell and Thom Watson. There are plenty of characters here, so be prepared to keep a scorecard. Mosley has moved from mid-twentieth-century LA to twenty-first-century New York City, but his work retains the atmosphere one expects. The 21st century and the east coast have the same sorts of gangsters, corrupt officials, colorful local characters, gorgeous women, soiled marriages, double-crosses and body counts as that other century and that warmer climate. Mosley updates with some recent technology to stay current. But the feel is the same, grimy, engaging, threatening and comfortable. You know what you are getting in a Walter Mosley mystery. And Mosley delivers, in spades.
