Psychologist Dr. Nicholas Thesiger is forced to break from his never-ending New York City routine of shuttling from apartment to bar to office and back to apartment by his wife and her family's annual summer reunion in the Hamptons. She optimistically hopes that this time away from the city will rejuvenate him, but has somehow failed to consider the antagonistic nature of Nick's relationship with her family. Far from his area of comfort and surrounded by hostile in-laws, Nick falls to pieces and goes on an offensive that leads to his biggest mistake, the one that ends it all.- Third in the Behind the Psychologist Trilogy -- The One Behind the Psychologist -- The Two Behind the Psychologist -- The Three Behind the Psychologist -
