From New York Times bestselling author Tess Gerritsen comes a chilling follow-up to The Spy Coast, plunging the Martini Club into the search for a missing teen—with a startling connection to their own pasts.

When former spy Maggie Bird retired to the seaside hamlet of Purity, Maine, she settled in for a quiet life with breathtaking views. But enemies from her past soon threatened to destroy everything.

Maggie survived, thanks to her wits and the collective intelligence of the Martini Club, the circle of ex-CIA friends in her cocktail-sipping book club. Their handiwork, however, caught the attention of young police chief Jo Thibodeau. Now Jo and her neighborhood ex-spies have an uneasy alliance.

After a teenager vanishes—and Maggie’s neighbor becomes the prime suspect—she joins the investigation, determined to prove her friend’s innocence. But the girl’s wealthy family pushes for an arrest. And when authorities discover a long-dead corpse in a nearby pond, the case becomes doubly complicated, with unthinkable ties to long-buried secrets.

As Jo grapples with two unexplained mysteries, the Martini Club races to uncover the truth behind shadowy secrets…before more lives are lost.

International bestselling author Tess Gerritsen took an unusual route to a writing career. A graduate of Stanford University, she later earned her MD at the University of California, San Francisco. While on maternity leave as a physician, she began to write fiction, publishing her first novel in 1987. She has since sold over forty million books in forty countries, winning both the Nero and RITA awards.

Gerritsen’s novels have been major bestsellers around the world. Critics praise her books as “pulse-pounding fun” (Philadelphia Inquirer), “scary and brilliant” (Toronto’s Globe and Mail), and “polished, riveting prose” (Chicago Tribune). Publishers Weekly dubbed her the “medical suspense queen.”

Gerritsen’s series featuring homicide detective Jane Rizzoli and medical examiner Maura Isles inspired the TNT television series Rizzoli & Isles.

Now retired from medicine, Gerritsen lives in Maine and writes full time.
