It's a nice start but hardly a chapter. I didn't even have to scroll down to read it. I like the details and suspense you've begun to build. I'm not too sure about the part about he breathing as little as possible. I don't think that breathing could cause chains that hold the prisoner to move. Unless she's chained in an unusual way. If that's the case, I'd like to see more detail about the chains.
With love, always,
