Ripley Under Water (Ripley #5)

Tom Ripley passes his leisured days at his French country estate tending the dahlias, practicing the harpsichord, and enjoying the company of his lovely wife, Heloise. Never mind the bloodstains on the basement floor. But some new neighbors have moved to Villeperce: the Pritchards, just arrived from America. They are a ghastly pair, with vulgar manners and even more vulgar taste. Most inconvenient, though, is their curiosity. Ripley does, after all, have a few things to hide. When menacing coincidences begin to occur, a spiraling contest of sinister hints and mutual terrorism ensues, resulting in one of Patricia Highsmith's most elegantly harrowing novels to date.
