Molly Harbison hates being asked “What do you do?” more than cleaning the ring around the bathtub or digging Cheerios and raisins out of the car’s back seat. She’s tried on every possibility from a flip Domestic Goddess to a simple declarative Mom. She jumps at the chance to make some extra money as a secret shopper. But when she’s assigned to shop an online dating site…things get tricky. For one, she realizes her husband doesn’t exactly meet her checklist of “must haves” for the perfect man, not at all like her dating site Mr. Perfect. For another, the FBI wants her to actually keep her date with Mr. Perfect, who just may be the perfect serial killer.

After tangling with a shopping mall serial killer (in Shop and Let Die) Molly Harbison promised to give up her mystery shopping for a "real" job. True to her vow, she applies for a job at the university where her husband works, begins the awkward and rocky interview process, and stumbles across a new mystery. Someone on the campus is a master identity thief. While Molly tries to figure out who she is, as a mother, a daughter, a wife, and where her career interests lie, a murder brings in the FBI. Molly finds herself going undercover once again.

Molly Harbison has decided that being a mystery shopper is the perfect job for a busy mother. But when the family’s vacation plans turn out to be more expensive than expected, Molly turns to entering sweepstakes to earn some extra money. Her simple plan to earn extra cash soon sends James Connery, the annoyingly attractive FBI agent, to Molly’s door once more. Seems someone she knows is running a fraudulent sweepstakes operation, and the FBI wants Molly to help catch the culprit. Molly is happy to help—as long as it doesn’t interfere with the family vacation.
