He twisted his heavy mouth into a faint smile⁠—he was one of those saturnine people who smile with the corners of the mouth down⁠—and bowed his acknowledgment of my complaisance. The main entrance to the enclosure was passed; it was a heavy wooden gate, framed in iron and locked, with the cargo of the launch piled outside it, and at the corner we came to a small doorway I had not previously observed. The white-haired man produced a bundle of keys from the pocket of his greasy blue jacket, opened this door, and entered. His keys, and the elaborate locking-up of the place even while it was still under his eye, struck me as peculiar. I followed him, and found myself in a small apartment, plainly but not uncomfortably furnished and with its inner door, which was slightly ajar, opening into a paved courtyard. This inner door Montgomery at once closed. A hammock was slung across the darker corner of the room, and a small unglazed window defended by an iron bar looked out towards the sea.
