A Murder in Sumerlake (en Inglés) - W.K. Penn

Set in the post-war 1950s, private investigator Jack Blake finds himself navigating the halls of The Rose Del Mar Hotel, an exclusive refuge for the wealthy, where the town's elite have all gathered for an auction. But as the final bids are placed, a hotel tycoon is found murdered. With no clear means of escape and every guest accounted for, Jack finds himself in a room full of suspects: wealthy patrons, socialites, and trusted staff, each with carefully guarded secrets. He must team up with a small-town police chief to delve into the art world and uncover corruption, deceit, and long-buried grudges.
