Just a few years ago, Corie Geller was busting terrorists as an agent for the FBI. But at 35, she traded in her badge for the stability of marriage and motherhood. Now Corie is married to the brilliant and remarkably handsome Judge Josh Geller and is the adoptive mother of his lovely 14-year-old daughter. Between cooking meals and playing chauffeur, Corie scouts Arabic fiction for a few literary agencies and, on Wednesdays, has lunch with her fellow Shorehaven freelancers at a so-so French restaurant. Life is, as they say, fine.

But at her weekly lunches, Corie senses that something's off. Pete Delaney, a milquetoast package designer, always shows up early, sits in the same spot (often with a different phone in hand), and keeps one eye on the Jeep he parks in the lot across the street. Corie intuitively feels that Pete is hiding something - and as someone who is accustomed to keeping her FBI past from her new neighbors, she should know. But does Pete really have a shady alternate life, or is Corie just imagining things, desperate to add some spark to her humdrum suburban existence? She decides that the only way to find out is to dust off her FBI toolkit and take a deep dive into Pete Delaney's affairs.

Always sassy, smart, and wickedly witty, Susan Isaacs is at her formidable best in a novel that is both bitingly wry and ominously thrilling.
