Tess Gerritsen “The Summer Guests” – Hamptons Whodunit 2025

Internationally bestselling author Tess Gerritsen took an unusual route to her writing career. A graduate of Stanford University, Tess went on to medical school at the University of California, San Francisco, where she was awarded her M.D. While on maternity leave from her work as a physician, she began to write fiction and in 1987, her first novel, CALL AFTER MIDNIGHT, was published. It was just the first of 32 suspense novels that she’s written over a 36-year writing career.

She joined Brian Cosgrove and Diane Masciale as a guest of honor at the 2025 Hamptons Whodunit festival, talking about her prolific career, what readers might expect to come next, and more.
