We peered eagerly inside the gate, but could distinguish no sign of the reptile which had so strangely attracted my friend's attention in the first instance. It had no doubt withdrawn among the plants and shrubs in the little smoke-dried garden, and was watching us unseen. Without hesitation, in order not to attract the curiosity of any passer-by whose attention might be arrested by Patterson's uniform, we walked straight to the area door, and gaining the kitchen, at once lit the gas. As he had said, there was every sign that the place had been recently occupied, but with only a cursory examination of the basement we passed upstairs to the dining-room. Here we also lit the gas and saw that the table had been laid for three persons in a manner quite luxurious, with real silver, cut glass and tiny vases of fresh flowers arranged artistically. Beside each plate were blue glass finger-bowls filled with water which gave out a strong perfume of roses. The chairs had been placed, and the _hors d'oeuvres_, olives, anchovies and caviare were already on the table, showing that all preparations for dinner had been made. Yet strangely enough, in the kitchen the greater part of the meat and vegetables remained uncooked. From this room we passed into the smaller one adjoining, lighting the gas as we went, but this seemed to have been used as a smoking-room, and contained nothing of note. It was, however, in the drawing-room above where we made the most astounding discoveries. The apartment was spacious for the size of the house, upholstered in pale-blue with furniture of expensive character, and large growing palms placed on stands. In the centre was a great circular settee, and in the corners wide soft divans of pale-blue velvet with golden fringe. Comfort and luxury had been studied by whoever had furnished the place, for as we lit one of the side gas-brackets we saw that it was really a very artistic room, the floor covered with a real Turkey carpet of softest hues, while the few paintings on the walls were choice examples of well-known artists. At the end opposite the grate was suspended from the ceiling by three gilt chains the mysterious little red lamp, burning steadily without a flicker, and beneath it, fallen back in a large armchair, was a woman, whose face, although waxen white, was eminently beautiful. The paleness of death was upon her, yet her handsome head with its wealth of gold brown hair was pillowed upon the cushion of yellow silk, and upon the cold, slightly-parted lips there played a strange, bitter smile. She was young, twenty or so, dressed in an artistically-made gown of pale mauve, trimmed with lace. Her teeth were even and perfect; her cheeks round and well-moulded; her chin slightly protruding, and a piquant little nose; but that smile in death seemed revolting in its hideousness. Her eyes large, of a deep blue, once luminous as stars no doubt, but now dull and filmy, were wide
