The Room in the Dragon Volant

I bolted my door, put on my greatcoat, and placed my pistols one in each pocket. I now applied my key to the secret locks; drew the wainscot door a little open, took my strong box under my arm, extinguished my candle, unbolted my door, listened at it for a few moments to be sure that no one was approaching, and then crossed the floor of my room swiftly, entered the secret door, and closed the spring lock after me. I was upon the screw-stair in total darkness, the key in my fingers. Thus far the undertaking was successful.
