Obsession

PUBLISHERS WEEKLY 26 FEB. 2007

The 21st Alex Delaware novel (after 2006's Gone) from bestseller Kellerman contains fewer twists than usual for this contemporary thriller series. Once again, Delaware, an accomplished psychologist, teams with his friend Milo Sturgis, an LAPD detective, to probe a mystery, though this time there's considerable doubt as to the nature of the puzzle. Teenager Tanya Bigelow, whom Delaware treated as a child for obsessive-compulsive disorder, consults him because her aunt Patty, who raised her, conveyed a cryptic message just before she died, apparently confessing to a crime. Shortly after Delaware and Sturgis start investigating, one of Patty's former neighbors turns up dead, the first in a series of corpses that appear, possibly as a result of the duo's turning over old rocks. Since the identity of the killer is revealed relatively early on, the final sections are short on suspense.
