47. The Scarecrow- Michael Connelly
Jack McEvoy covers a murder involving a woman asphyxiated and stuffed in the trunk of a car. The case looks easily solved until he and his partner do a search and find another virtually identical murder in Las Vegas, and he determines that both killings are the work of a serial killer. He teams up with his old flame FBI agent from The Poet, and together they solve the case. And ride off together into the sunset.
