Edward's hand over her mouth was as surprising as it was offensive, and Mable would have shoved him away and shouted if he didn't look so worried.  She held on tight to his hand as they ran down another alley, but Mable kept glancing back.  She only half heard what Edward was saying.

"Sharks... Edward, is it safe to be here?  What part of town are we in?"

Mable turned her head to look behind herself again, swearing she saw a shadow move out of the corner of her eye.  As she did so, her foot hit something and slipped from beneath her.  She fell, and hit the ground hard.
