Cinnamon Kiss, the 10th entry in Walter Mosley’s superb Easy Rawlins detective series, opens in atypically melodramatic fashion. Easy is desperate for funds to save his adopted daughter from a rare blood disease. When a man unsubtly named Robert E. Lee asks Easy to help track down a white attorney and the lawyer’s woman (the titular Cinnamon), Easy can’t refuse. Despite that overwrought setup, Mosley soon settles into his well-worn groove, vividly describing the changing times (Easy rolls through the hippiefied streets of 1966 San Francisco) while lingering on the effects of the past (Easy’s L.A. is still smarting from the 1965 Watts riots). Even with its ”where did that come from” resolution, Cinnamon convincingly wraps a mystery within the larger context of history and race in Los Angeles. Mosley could probably take an elderly Easy into the Rodney King era with no problem at all.
