Tess Gerritsen brings back The Martini Club in the second book in the series, The Summer Guests. Once again set in Purity, Maine, it features a small group of former CIA agents who dig into trouble in the small tourist town.

The book opens with a flashback to 1972 when a local man, Sam Tarkin, killed four people on a main street. Although it would be years until anyone discovered the truth, the incident affected everyone in town, especially Tarkin’s son.

Now, in the present time, the Conovers arrive back in Purity. They are summer residents who own one of the biggest houses, a cottage, on Maiden Pond. Although the town benefits from the Conovers’ money, there’s a great deal of resentment toward the powerful family, including the now deceased patriarch, George. The family has come from Boston and New York to scatter George’s ashes. But, Ethan’s wife, Susan and her teen daughter, Zoe, barely know the rest of the family.

Zoe’s delighted to be able to swim in Maiden Pond. She’s a mermaid who loves the water. But, just a couple days after arrival, Zoe disappears. And, it becomes an all-out search for the missing girl. Susan’s the only one convinced her daughter did not run away. When the police, under Acting Police Chief Jo Thibodeau, drag the pond, they find remains. But, the body is already a skeleton, not the missing girl.

It doesn’t take long for the Martini Club to work their way into the investigation. They have skills and knowledge that frustrate Jo. She can’t compete with them with her small police force. But, even their suggestions can take a wrong turn.

I’ve seen comments that say there should have been more Martini Club in this second book. However, as Jo comes into her own as an investigator, and the members of the Martini Club become aware of their own problems with aging, I felt the two elements, local police and former CIA, blended beautifully. Now, Gerritsen just needs to write the next book without a missing teen.
