The Door-Seal Alibi: A Locked-Room Mystery Thriller

Eidolon House sells transformation through silence. No phones. No talking. No exceptions. Guests surrender their devices at intake and wear color-coded wristbands that decide which doors will open. At night, suite seals "prove" no one entered after lights-out. Privacy is the product. Rules are the brand. So when benefactor Lila Kincaid is found dead inside the private Recovery Suite-door sealed, lock engaged, access logs spotless-the retreat's leaders push a tidy conclusion: a tragic medical event.
Case closed. Quietly. Senior paramedic Ro Malloy has worked too many scenes to trust tidy. The room is too neat. The body says the story is wrong. And in a place engineered to record compliance, Ro notices what everyone else treats as gospel: the rules don't just keep order. They create the perfect alibi. With a closed circle of suspects, schedules that sound airtight, and an institution desperate to protect its image during audit week, Ro and Detective Elise Marlowe chase the one thing more dangerous than a locked door-procedure.
Because an intact seal can keep a door closed. It can't keep a lie from breathing.
