Annie Fitch, a former police detective, struggles to make ends meet as a private investigator in the sleepy town of Leesburg, Virginia. On partial disability because of gunshot injuries, she's relegated to doing surveillance gigs and background checks. But things are looking up, since her on-again, off-again relationship is back on and might stay that way.

When Annie is hired by Laura Carlton to follow her husband to get evidence of cheating, Annie is certain the case won't take long. Nick Carlton grew up with money and privilege and has a sex addiction dating back to his high school days. But things go sideways when Annie finds her target dead in an alley just a few blocks from her own home.

Working with her former partner, Gunnar Jansson, Annie digs deeper into Carlton's background, slowly excavating his past to reveal the multiple suspects and motives. The list includes his many lunch-hour-tryst partners, a local shop owner, and his business partner, among others. Layer by layer, Annie uncovers a truth that runs much deeper than anyone expected.
