Invisible Prey

Bestseller Sandford opts for a contemplative procedural rather than a high-octane nail-biter for his 17th novel to feature Minneapolis detective Lucas Davenport (after 2005's Broken Prey). The brave and intelligent Davenport, one of contemporary crime fiction's more congenial sleuths, is working a politically sensitive case?state senator Burt Kline is on the edge of being arrested for having sex with a minor?when he's called in to investigate the beating death of wealthy widow Constance Bucher and her maid. Bucher lived in a mansion stuffed with antiques, though it's unclear if robbery was the motive for the murders. Several run-of-the-mill suspects are dealt with before the reader learns the identity of the two killers, who continue to murder a string of folks all variously connected to the Bucher slaying. Eventually, the Bucher and Kline cases come together in an unexpected way. Interesting and unusual supporting characters, good and bad guys alike, enhance an intriguing puzzle.
