Eve

You're walking from the pub in London's East End when you hear a woman scream followed by a man's hoarse shout. You are nearly bowled over by a terrified woman with a ripped shirt. As you turn back to the alley she ran from you hear a crunch and the sound of a muffled thump. Using the light on your cellphone you shine it into the narrow alley. A man lies on the ground, his neck snapped. The corpse is also bent at an odd angle. Standing over it is a woman that has to be almost seven feet tall. She has grayish skin, an aloof almost annoyes dignified expression as she regards you.
