After a time the cautious rattling ceased, and I heard the room to the north entered with a pass key. Then the lock of the connecting door to my room was softly tried. The bolt held, of course, and I heard the floor creak as the prowler left the room. After a moment there came another soft rattling, and I knew that the room to the south of me was being entered. Again a furtive trying of a bolted connecting door, and again a receding creaking. This time the creaking went along the hall and down the stairs, so I knew that the prowler had realised the bolted condition of my doors and was giving up his attempt for a greater or lesser time, as the future would shew.
