I looked down and took breath. The maid was removing the crumbs in the lighted room, and the square was empty as before. What a blessing it was the end of the season! Many of the houses remained in darkness. I looked up again, and Raffles was drawing his left leg over the balcony railing. In another moment he had disappeared through one of the French windows which opened upon the balcony, and in yet another he had switched on the electric light within. This was bad enough, for now I, at least, could see everything he did; but the crowning folly was still to come. There was no point in it; the mad thing was done for my benefit, as I knew at once and he afterward confessed; but the lunatic reappeared on the balcony, bowing like a mountebank—in his crape mask! I set off with the empty chair, but I came back. I could not desert old Raffles, even when I would, but must try to explain away his mask as well, if he had not the sense to take it off in time. It would be difficult, but burglaries are not usually committed from a bath-chair, and for the rest I put my faith in Dr. Theobald. Meanwhile Raffles had at least withdrawn from the balcony, and now I could only see his head as he peered into a cabinet at the other side of the room. It was like the opera of _Aïda_, in which two scenes are enacted simultaneously, one in the dungeon below, the other in the temple above. In the same fashion my attention now became divided between the picture of Raffles moving stealthily about the upper room, and that of the husband and wife at table underneath. And all at once, as the man replenished his glass with a shrug of the shoulders, the woman pushed back her chair and sailed to the door. Raffles was standing before the fireplace upstairs. He had taken one of the framed photographs from the chimney-piece, and was scanning it at suicidal length through the eye-holes in the hideous mask which he still wore. He would need it after all. The lady had left the room below, opening and shutting the door for herself; the man was filling his glass once more. I would have shrieked my warning to Raffles, so fatally engrossed overhead, but at this moment (of all others) a constable (of all men) was marching sedately down our side of the square. There was nothing for it but to turn a melancholy eye upon the bath-chair, and to ask the constable the time. I was evidently to be kept there all night, I remarked, and only realized with the words that they disposed of my other explanations before they were uttered. It was a horrible moment for such a discovery. Fortunately the enemy was on the pavement, from which he could scarcely have seen more than the drawing-room ceiling, had he looked; but he was not many houses distant when a door opened and a woman gasped so that I heard both across the road. And never shall I forget the subsequent tableaux in the lighted room behind the low balcony and the French windows.
