The number kept appearing on his computer screen. He didn’t have a clue what was going on but his anger was slowly being replaced by fear.
There was nothing wrong with the computer. He had built the thing himself, ran regular checks and could solve any problems.
No matter what he was doing, the screen would flicker, turn black then the number 54 would fill the screen before the computer shut down.
It was impossible, no one knew and yet someone clear did. It couldn’t be a coincidence anymore…
His secret was out, he was the city’s serial cat killer.
