The lobby’s glass doors had been shattered from the inside. Rain slanted in. She sat at the threshold, looked back once at the long hallway of bad memory, and then stepped into the wet March dark.

The third floor was empty. The kennels of the other cats—13, 15, 16—were dark. Their occupants had already been moved to the incinerator room earlier that day. Lucky paused at each cage anyway, whiskers forward, as if paying respects.

He missed what was obvious. Lucky wasn’t broken. She was full.

She always understood.

The magnetic lock on her cage clicked open.

No one caught Lucky. She appears now and then on loading docks, in cemetery gardens, outside the windows of children who cry in their sleep. If you see a black cat with penny-colored eyes, do not try to pet her. Do not call her.

But the techs just called her Lucky.

She stepped out into the corridor. The emergency lights painted everything red. Two guards lay slumped against the wall, not dead but sleeping with their mouths open, their tasers still holstered. Lucky stepped over them without a sound.

The designation on the kennel was a sterile, government-issue stencil: Subject 14. Felis catus. Melanistic.
