A shadow gleamed across the weathered brick wall of a building as the moon peaked out from behind the night clouds. It stopped abruptly when it came to face and irregular shaped shadow. The first shadow laughed and shifted into it's human form. It could have killed the beast as a shadow but it wanted a challenge. It pulled out a stethi, a special knife used only in the shadow world, and sliced at the monstrous shadow. With one expert swipe the shadow melted to darkness. Then first shadow, now a human, put the blade in his aviator jacket pocket and calmly walked out of the ally and out onto the busy night streets of London.
