An escape from a Zombie demon

Hi everyone this is my entry for the #50wordsstory organised by @miniature-tiger. Sorry the story is too short, I wish to write more but then I have to stick to the rules.
After running a mile without an escape.'' I whispered to the demon, ''kill me instead.'' The zombie grabbed my arms and would sink his dirty teeth into my neck. Suddenly someone more powerful chopped it's head from the back. His blood made a splash as it spluttered on the floor.
