The retired officer’s badge number was harder to place. na1117 could be noise, could be an address, could be a nod to a name. Mira’s fingertips found the edge of the locker where the code had been stamped, the metal cold. She had a hunch that "WMV" pointed to a file — footage captured by an old security camera at the transit depot, rendered obsolete but not destroyed. If the footage existed, the mural, GOGO’s last act, and the retired officer’s silence would all be threads she could pull.
