“Hullo, there!” I shouted. But there came no reply. Nor could I distinguish anybody in the courtyard. It was at best a shadowy place at night, with no artificial light after the news agent--who had a permanent booth there--had shut up and gone home. Gone he was now, and to me the yard seemed deserted. Some men had been at work during the day on a drain-pipe near the booth, and I reflected that probably their litter had provided the stone wherewith my window had been smashed. As I looked, however, two men came hurrying from the passage into the court, and going straight into the deep shadow of one corner, presently appeared again in a less obscure part, hauling forth a third man, who must have already been there in hiding. The man--who appeared, so far as I could see, to be smaller than either of his assailants--struggled fiercely, but without avail, and was dragged across toward the passage leading to the street beyond. But the most remarkable feature of the whole thing was the silence of all three men. No cry, no exclamation, or expostulation escaped any one of them. In perfect silence the two hauled the third across the courtyard, and in perfect silence he swung and struggled to resist and escape. The matter astonished me not a little, and the men were entering the passage before I found voice to shout at them. But they took no notice, and disappeared. Soon after I heard cab wheels in the street beyond, and had no doubt that the two men had carried off their prisoner. [Illustration: “THE MAN . . . STRUGGLED FIERCELY.”] I turned back into my room a little perplexed. It seemed probable that the man who had been borne off had broken my window. But why? I looked about on the floor, and presently found the missile. It was, as I had expected, a piece of broken concrete, but it was wrapped up in a worn piece of paper, which had partly opened out again as it lay on my carpet, thus indicating that it had only just been hastily crumpled round the stone. But again, why? It might be considered a trifle more polite to hand a gentleman a clinker decently wrapped up than to give it him in its raw state; but it came to much the same thing after all if it were passed through a shut window. And why a clinker at all? I disengaged the paper and spread it out. Then I saw it to be a rather hastily written piece of manuscript music, whereof I append a reduced facsimile:--
