I could not, I decided, risk an emergence into the corridor; where my footsteps would surely be heard, and where the difficulties of entering the desired room would be insuperable. My progress, if it was to be made at all, would have to be through the less solidly-built connecting doors of the rooms; the locks and bolts of which I would have to force violently, using my shoulder as a battering-ram whenever they were set against me. This, I thought, would be possible owing to the rickety nature of the house and its fixtures; but I realised I could not do it noiselessly. I would have to count on sheer speed, and the chance of getting to a window before any hostile forces became coordinated enough to open the right door toward me with a pass-key. My own outer door I reinforced by pushing the bureau against it—little by little, in order to make a minimum of sound.
