Sabatini smiled tolerantly.
"My dear fellow," he said, "why should I? Be reasonable! When you reach my age you will find that silence is often best. As a matter of fact, in this ease my sympathies are very much involved. It is in the mind of many of those who hold the strings that when that revolution does take place it will be I who shall lead it."
Arnold was again bewildered.
"But you," he protested, "are of the ancient nobility of Europe. What place have you among a crowd of anarchists and revolutionaries?"
"You jump at conclusions, my young friend," remarked Sabatini. "The country of which we have spoken is my country, the country from which, by an unjust decree I am exiled. There are among those who desire a change of government, many aristocrats. It is not only the democracy whose hatred has been aroused by the selfish and brutal methods of the reigning house."
Arnold got down from his table and walked to the window. The telephone rang with some insignificant inquiry from a customer. The incident somehow relieved him. It brought him back to the world of every-day events. The reality of life once more obtruded itself upon his conscience. All the time Sabatini lounged at his ease and watched him, always with the faint beginning of a smile upon his lips.
"What I have told you," the latter continued, after a few moments' pause, "must not, during these days, pass beyond the four walls of this singularly uninviting-looking apartment. I have nothing to add or to take from what I have said. The subject is closed. If you have more questions on any other subject, I have still a few minutes."
"Very well, then," Arnold said, coming back to his place, "let us consider the Rosario matter disposed of. Let us go back for a moment to Starling. Tell me why you and your sister saw danger to yourselves in Starling's nervous breakdown? Tell me why, when I returned to Pelham Lodge with her that night, she found a dead man in her room, a man whose body was afterwards mysteriously removed?"
"Quite a spirited number of questions," Sabatini remarked. "Well, to begin with, then, Rosario signed his death-warrant the moment he wrote his name across the parchment which guaranteed the loan. On the night when you first visited Pelham Lodge we heard the news. I believe that Lalonde and his friends would have killed him that night if they could have got at him. Lalonde, however, was a person of strange and inaccessible habits. He hated all aristocrats, and he refused even to communicate with me. Speaking for myself, I was just as determined as Isaac Lalonde that Rosario should never conclude that loan. I told him so that night—Starling and I together. It was thought necessary, by those whose word I am content to accept, that what I had to say to Rosario should come through Starling. It was Starling, therefore, who told him what his position would be if he proceeded further. I must admit that the fellow showed courage. He took a note of Starling's words, which he declared at the time should be deposited in his safe, so that if anything should happen to him, some evidence might be forthcoming. The police, without a doubt, have been in possession of this document, and, curiously enough, Starling was at the Milan that day. You will perceive, therefore, that in the absence, even, of a reasonable alibi it might be difficult to prove his innocence. To our surprise, however, for we had some faith in the fellow, instead of taking this matter with the indifference of a brave man, he has chosen to behave like a child. In his present half maudlin state he would, I am afraid, if in serious danger of conviction, make statements likely to cause a good deal of inconvenience to myself, my sister's friends, and others."
"Does he know himself who committed the murder?" Arnold asked.
