Guerta Cargol was not having a good Friday night.

After a long exhausting week working at a factory in the outskirts of Berlin,

she wanted nothing more than to get home to her bed.

The city was under a wartime blackout, and Guerta's carriage was almost completely dark.

Combined with the motion of the train, it was soothing, and she'd fallen asleep and missed her stop.

She managed to switch trains and started heading back in the right direction,

but she could see a ticket inspector heading down the aisle towards her.

No longer on her original train, she knew she was going to be charged to find.

One she couldn't afford to pay.

Guerta looked up at the uniformed young man and told him what had happened.

She braced for the worst, but the man smiled sympathetically.

It happens all the time, he told her, ride with me and you'll be fine.

She gladly accepted the friendly stranger and followed him into an empty carriage.

But soon after the train left the station, the man turned to Guerta,

and he was unrecognizable.

Gone was the kind ticket inspector replaced with a man possessed.

Looking at his face, Guerta was terrified.

She knew she'd made a terrible mistake.

Hi, I'm Greg Poulsen.
