I heard a bump coming from downstairs.

I heard a bump coming from downstairs. I live in an old house, so I thought nothing of it. Probably just some old tiles falling or whatever. But then, another bump, a little closer to the stairs.

Might as well take a look.I took a flashlight and went to the door at the top of the stairs.I breathed deeply and unlocked the door. Almost as soon as I did, a man so thin you could see his ribs lunged at me.We struggled hard- he had his hands around my throat- but with a mighty swing, I knocked him unconscious. That was close, I thought as I carried him back downstairs.

He almost got out.
