We retired about eleven, but I did not sleep well. Bolton had a surprisingly good police force for so small a town, and I could not help fearing the mess which would ensue if the affair of the night before were ever tracked down.

After the clock had struck three the moon shone in my eyes, but I turned over without rising to pull down the shade. Then came the steady rattling at the back door.
