I walked in, and he left me, shutting the door. It then struck me that I had neither given him my name nor mentioned the mass of smoke and sparks which I had seen vomited from the tower. I sprang to the door again, meaning to call after the man a word of warning in regard to the fire, but he was already out of sight. He could not have gone back the way that he had come, or I should certainly have seen him walking down the dimly-lighted passage, there being no door save that at the extreme end, which he would not yet have had time to reach. I did not see how he could have disappeared so suddenly, but returning whence I had come, I looked about in vain for a bell. I was sure now that this room must be situated in that part of the new wing which adjoined the tower. In glancing at the house from outside, I had fancied that the square, squat wall must be that of a studio, as there were no windows, but a high, domed skylight on top. Now I saw that though the outer building was square, the room within was octagon in shape. It was, perhaps, a studio, as I had fancied, but there was something of the free-and-easy negligence of an Oriental smoking-room about it. The walls were hung with embroidered Indian materials, and a low divan ran down part way. Between the hangings were panels of sandal-wood, ornamented with bits of mirror in the Burmese fashion, and half hidden with curious foreign weapons, daggers, swords, and spears, and even a Zulu assegai or two. On the floor stood a hookah, and on a small inlaid table were a couple of curious little objects which I knew to be opium pipes. In one corner, as though it had been pushed aside, stood an easel with a canvas upon it, which was half covered with a piece of drapery. The skylight was partly concealed with red silk blinds, drawn across the staring glass, and from the centre of the dome was suspended a large jewelled lamp. It was from this that all the light in the studio proceeded at present, and though there was no fireplace, the room was warm--indeed, insufferably hot. This fact, taken together with the studio's proximity to the tower, made me feel more certain than before that some flue in this modern portion of the house had caught fire. I searched the panels for a bell, but found none, and at last lifted several of the curtains that draped the larger part of the octagonal walls. Under the first two that I raised only a blank space of dark wood was visible, but under the third I was surprised to find a small, secretive-looking door.
