Lethal Prey, Sandford - B

       This is an investigation that involves both Lucas Davenport and Virgil Flowers. They are tasked to look into a cold case, opened primarily because the victim's twin sister is well-connected and gives to the governor's campaign. Twenty years ago, pretty and flirtatious Doris Grandfelt was killed, apparently by a man she had just had sex with. Actually, she had been killed by the man's girlfriend. As the wealthy sister has offered a $5M reward, flocks of true crimers are all over town. As Davenport and Flowers dig into the matter, they learn that Doris was sidelining as an escort. They eventually focus on a complex and sophisticated killer and do their best to bring the murderer to justice. The author has been cranking out Lucas Davenport novels annually since 1989. They are always well-done police procedurals, with insights into the culture of Minnesota and generally a fun read.
