Day 2,973

They tracked it to a motel near the mountain pass where it had been feeding on solo travellers for almost a year, if the pile of abandoned cars was anything to go by. And it was, as it always was with these things.

They kill whoever seems the most untroublesome and,  using their genetic template, they either move on to new feeding grounds or dispose of any evidence tying them to their latest victim. In this case, it checked its victims out of the motel and drove their cars deep into the forest before heading back in the form of small birds or rats.

It eventually made a mistake, as they all do. It got too complacent and cocky and answered a call from its victim's phone. The voice is one thing they can never get right and while ot made excuses of a sore throat and a bad signal - we'd just been given all the evidence we needed to strike.
