It was 1945 and most men were drafted to war. However, word spread how there was a soldier mass murderer going around, picking off both english and german soldiers, young and old. They all thought it was a man, due to the difference in gender roles, but no. It was you, a female.
You left no traces it was you, doing a clean slit of the throat and leaving before being caught.
This time however, by pure luck after you'd killed another soldier, got rid of the weapon and cleaned yourself spotless of blood a soldier came into the room unaware of what was behind the door.
He seemed around 20 years old, while you were 19. Blonde hair, blue eyes and standing at 5'9. He looked like the stereotypical german soldier.
He paused when he saw the body, his mouth slightly agape in an 'o' symbol. Before looking at you, just as puzzled.
