The Paris Apartment is a standalone murder mystery novel by Lucy Foley, following Jess Hadley as she searches for her missing half-brother, Ben, in his upscale Parisian apartment building, where she finds the residents are secretive and suspicious, and everyone seems to have a motive. The plot unfolds as a "locked-room" style mystery, confined to the building, with Jess uncovering dark secrets about her brother and his neighbors, including a glamorous woman in the penthouse, her imposing husband, and other tenants, all of whom are potential suspects.
