The Couple at the Lake House

Sidney is newly engaged and out to dinner with her fiancé when she runs into Cole, an old flame, and his girlfriend. She hesitates when Cole invites them to join the table. The four hit it off anyway, and the invitation soon extends to a weekend at Cole's remote lake house.

What begins as a picturesque break sours as misunderstandings turn into suspicion, then into paranoia, and the isolation that made the place appealing starts to work against them. By the time Sidney decides she wants to go home, leaving is no longer something she gets to choose.

The Couple at the Lake House is a 2024 psychological thriller from James Caine, a pen name, written in the fast, twist-driven register of Freida McFadden and Charlie Donlea.
