Then turning to the Police Agent he addressed him in Italian, speaking so fast that it was impossible for me to follow him. From what little I could make out, however, I gathered that he was rating him for daring to interfere with his concerns. When, at the end of three or four minutes, he paused and spoke more slowly, this was the gist of his speech—

"You know me and the power I control. You are aware that those who thwart me, or who interfere with me and my concerns, do so at their own risk. Since no harm has come of it, thanks to certain good friends, I will forgive on this occasion, but let it happen again and this is what your end will be."

"Presently a picture shaped itself in the cloud."

As he spoke he took from his pocket a small glass bottle with a gold top, not unlike a vinaigrette, and emptied some of the white powder it contained into the palm of his hand. Turning down the lamp he dropped this into the chimney. A green flame shot up for a moment, which was succeeded by a cloud of perfumed smoke that filled the room so completely that for a moment it was impossible for us to see each other. Presently a picture shaped itself in the cloud and held my attention spell-bound. Little by little it developed until I was able to make out a room, or rather I should say a vault, in which upwards of a dozen men were seated at a long table. They were all masked, and without exception were clad in long monkish robes with cowls of black cloth. Presently a sign was made by the man at the head of the table, an individual with a venerable grey beard, and two more black figures entered, who led a man between them. Their prisoner was none other than the Police Agent whom Nikola had warned. He looked thinner, however, and was evidently much frightened by his position. Once more the man at the head of the table raised his hand, and there entered at the other side an old man, with white hair and a long beard of the same colour. Unlike the others he wore no cowl, nor was he masked. From his gestures I could see that he was addressing those seated at the table, and, as he pointed to the prisoner, a look of undying hatred spread over his face. Then the man at the head of the table rose, and though I could hear nothing of what he said, I gathered that he was addressing his brethren concerning the case. When he had finished, and each of the assembly had voted by holding up his hand, he turned to the prisoner. As he did so the scene vanished instantly and another took its place.

It was a small room that I looked upon now, furnished only with a bed, a table, and a chair. At the door was a man who had figured as a prisoner in the previous picture, but now sadly changed. He seemed to have shrunk to half his former size, his face was pinched by starvation, his eyes were sunken, but there was an even greater look of terror in them than had been there before. Opening the door of the room he listened, and then shut and locked it again. It was as if he were afraid to go out, and yet knew that if he remained where he was, he must perish of starvation. Gradually the room began to grow dark, and the terrified wretch paced restlessly up and down, listening at the door every now and then. Once more the picture vanished as its companion had done, and a third took its place. This proved to be a narrow street-scene by moonlight. On either side the houses towered up towards the sky, and since there was no one about, it was plain that the night was far advanced. Presently, creeping along in the shadow, on the left-hand side, searching among the refuse and garbage of the street for food, came the man I had seen afraid to leave his attic. Times out of number he looked swiftly behind him, as if he thought it possible that he might be followed. He was but little more than half-way up the street, and was stooping to pick up something, when two dark figures emerged from a passage on the left, and swiftly approached him. Before he had time to defend himself, they were upon him, and a moment later he was lying stretched out upon his back in the middle of the street, a dead man. The moon shone down full and clear upon his face, the memory of which makes me shudder even now. Then the picture faded away and the room was light once more. Instinctively I looked at the Police Agent. His usually swarthy face was deathly pale, and from the great beads of perspiration that stood upon his forehead, I gathered that he had seen the picture too.

"Now," said Nikola, addressing him, "you have seen what is in store for you if you persist in pitting yourself against me. You recognized that grey-haired man, who had appealed to the Council against you. Then, rest assured of this! So surely as you continue your present conduct, so surely will the doom I have just revealed to you overtake you. Now go, and remember what I have said."

Turning to the smaller man, Nikola placed his hand in a kindly fashion upon his shoulder.

"You have done well, Tomasso," he said, "and I am pleased with you. Drop our friend here at the usual place, and see that some one keeps an eye on him. I don't think, however, he will dare to offend again."
