A stranger arrived by train as the autumn leaves were falling on the ground. He appears to be a business traveler, but he is not. He is a predator, and has made many such trips to cities throughout the Midwest. Always, he arrived in darkness, committed mayhem, and slipped away without notice. This time will be different. He has chosen the wrong destination, and the residents rise up to fight him off. He will not be leaving, but no one can say exactly why.
