The Alibi Hour

A murder happens in the Hartwell Center-during the single hour when everyone has a documented alibi.

Badge scans. Elevator logs. Lobby cameras. A security dashboard that swears it "saw everything." The building's tenants breathe easy because the system proves they couldn't have done it. The case looks impossible on arrival, the kind of clean, untouchable mystery that dies in paperwork.

Detective Tessa Granger doesn't buy it.

The victim is Caleb Voss, a corporate fixer who made enemies professionally and collected leverage like insurance. The crime scene is too neat. The alibis feel too confident. Then Tessa finds the first crack-a timestamp drift so small nobody would notice unless they were hunting for a lie.

As pressure mounts from powerful ownership, nervous tenants, and lawyers who want the truth "contained," Tessa builds her own clock-raw feeds, device logs, independent time-until the building's perfect hour starts forging itself in real time. Someone didn't just commit murder. Someone engineered proof.

Because in a world where "evidence" can be manufactured, the most dangerous killer is the one who knows how to make the case look impossible.

THE ALIBI HOUR is a locked-room murder mystery for the modern age-where the building never blinks, and the dashboard can be taught to lie.
