He said a few words more, hesitatingly and disconnectedly, then stopped again.
I saw that the effort of expressing himself in English, on an occasion too serious to permit him the use of the quaint turns and phrases of his ordinary vocabulary, was painfully increasing the difficulty he had felt from the first in speaking to me at all. Having learnt to read and understand his native language (though not to speak it), in the earlier days of our intimate companionship, I now suggested to him that he should express himself in Italian, while I used English in putting any questions which might be necessary to my enlightenment. He accepted the proposal. In his smooth-flowing language, spoken with a vehement agitation which betrayed itself in the perpetual working of his features, in the wildness and the suddenness of his foreign gesticulations, but never in the raising of his voice, I now heard the words which armed me to meet the last struggle, that is left for this story to record.
 It is only right to mention here, that I repeat Pesco's statement to me with the careful suppressions and alterations which the serious nature of the subject and my own sense of duty to my friend demand. My first and last concealments from the reader are those which caution renders absolutely necessary in this portion of the narrative.
"You know nothing of my motive for leaving Italy," he began, "except that it was for political reasons. If I had been driven to this country by the persecution of my government, I should not have kept those reasons a secret from you or from any one. I have concealed them because no government authority has pronounced the sentence of my exile. You have heard, Walter, of the political societies that are hidden in every great city on the continent of Europe? To one of those societies I belonged in Italy--and belong still in England. When I came to this country, I came by the direction of my chief. I was over-zealous in my younger time--I ran the risk of compromising myself and others. For those reasons I was ordered to emigrate to England and to wait. I emigrated--I have waited--I wait still. To-morrow I may be called away--ten years hence I may be called away. It is all one to me--I am here, I support myself by teaching, and I wait. I violate no oath (you shall hear why presently) in making my confidence complete by telling you the name of the society to which I belong. All I do is to put my life in your hands. If what I say to you now is ever known by others to have passed my lips, as certainly as we two sit here, I am a dead man."
He whispered the next words in my ear. I keep the secret which he thus communicated. The society to which he belonged will be sufficiently individualised for the purpose of these pages, if I call it "The Brotherhood," on the few occasions when any reference to the subject will be needed in this place.
"The object of the Brotherhood," Pesca went on, "is, briefly, the object of other political societies of the same sort--the destruction of tyranny and the assertion of the rights of the people. The principles of the Brotherhood are two. So long as a man's life is useful, or even harmless only, he has the right to enjoy it. But, if his life inflicts injury on the well-being of his fellow-men, from that moment he forfeits the right, and it is not only no crime, but a positive merit, to deprive him of it. It is not for me to say in what frightful circumstances of oppression and suffering this society took its rise. It is not for you to say--you Englishmen, who have conquered your freedom so long ago, that you have conveniently forgotten what blood you shed, and what extremities you proceeded to in the conquering--it is not for you to say how far the worst of all exasperations may, or may not, carry the maddened men of an enslaved nation. The iron that has entered into our souls has gone too deep for you to find it. Leave the refugee alone! Laugh at him, distrust him, open your eyes in wonder at that secret self which smoulders in him, sometimes under the everyday respectability and tranquillity of a man like me--sometimes under the grinding poverty, the fierce squalor, of men less lucky, less pliable, less patient than I am-- but judge us not! In the time of your first Charles you might have done us justice--the long luxury of your own freedom has made you incapable of doing us justice now."
All the deepest feelings of his nature seemed to force themselves to the surface in those words--all his heart was poured out to me for the first time in our lives--but still his voice never rose, still his dread of the terrible revelation he was making to me never left him.
"So far," he resumed, "you think the society like other societies. Its object (in your English opinion) is anarchy and revolution. It takes the life of a bad king or a bad minister, as if the one and the other were dangerous wild beasts to be shot at the first opportunity. I grant you this. But the laws of the Brotherhood are the laws of no other political society on the face of the earth. The members are not known to one another. There is a president in Italy; there are presidents abroad. Each of these has his secretary. The presidents and the secretaries know the members, but the members, among themselves, are all strangers, until their chiefs see fit, in the political necessity of the time, or in the private necessity of the society, to make them known to each other. With such a safeguard as this there is no oath among us on admittance. We are identified with the Brotherhood by a secret mark, which we all bear, which lasts while our lives last. We are told to go about our ordinary business, and to report ourselves to the president, or the secretary, four times a year, in the event of our services being required. We are warned, if we betray the Brotherhood, or if we injure it by serving other interests, that we die by the principles of the Brotherhood--die by the hand of a stranger who may be sent from the other end of the world to strike the blow--or by the hand of our own bosom-friend, who may have been a member unknown to us through all the years of our intimacy. Sometimes the death is delayed--sometimes it follows close on the treachery. It is our first business to know how to wait--our second business to know how to obey when the word is spoken. Some of us may wait our lives through, and may not be wanted. Some of us may be called to the work, or to the preparation for the work, the very day of our admission. I myself--the little, easy, cheerful man you know, who, of his own accord, would hardly lift up his handkerchief to strike down the fly that buzzes about his face--I, in my younger time, under provocation so dreadful that I will not tell you of it, entered the Brotherhood by an impulse, as I might have killed myself by an impulse. I must remain in it now--it has got me, whatever I may think of it in my better circumstances and my cooler manhood, to my dying day. While I was still in Italy I was chosen secretary, and all the members of that time, who were brought face to face with my president, were brought face to face also with me."
I began to understand him--I saw the end towards which his extraordinary disclosure was now tending. He waited a moment, watching me earnestly--watching till he had evidently guessed what was passing in my mind before he resumed.
"You have drawn your own conclusion already," he said. "I see it in your face. Tell me nothing--keep me out of the secret of your thoughts. Let me make my one last sacrifice of myself, for your sake, and then have done with this subject, never to return to it again."
He signed to me not to answer him--rose--removed his coat--and rolled up the shirt-sleeve on his left arm.
"I promised you that this confidence should be complete," he whispered, speaking close at my ear, with his eyes looking watchfully at the door. "Whatever comes of it you shall not reproach me with having hidden anything from you which it was necessary to your interests to know. I have said that the Brotherhood identifies its members by a mark that lasts for life. See the place, and the mark on it for yourself."
He raised his bare arm, and showed me, high on the upper part of it and in the inner side, a brand deeply burnt in the flesh and stained of a bright blood-red colour. I abstain from describing the device which the brand represented. It will be sufficient to say that it was circular in form, and so small that it would have been completely covered by a shilling coin.
"A man who has this mark, branded in this place," he said, covering his arm again, "is a member of the Brotherhood. A man who has been false to the Brotherhood is discovered sooner or later by the chiefs who know him--presidents or secretaries, as the case may be. And a man discovered by the chiefs is dead. NO HUMAN LAWS CAN PROTECT HIM. Remember what you have seen and heard--draw what conclusions YOU like--act as you please. But, in the name of God, whatever you discover, whatever you do, tell me nothing! Let me remain free from a responsibility which it horrifies me to think of--which I know, in my conscience, is not my responsibility now. For the last time I say it--on my honour as a gentleman, on my oath as a Christian, if the man you pointed out at the Opera knows ME, he is so altered, or so disguised, that I do not know him. I am ignorant of his proceedings or his purposes in England. I never saw him, I never heard the name he goes by, to my knowledge, before to-night. I say no more. Leave me a little, Walter. I am overpowered by what has happened--I am shaken by what I have said. Let me try to be like myself again when we meet next."
He dropped into a chair, and turning away from me, hid his face in his hands. I gently opened the door so as not to disturb him, and spoke my few parting words in low tones, which he might hear or not, as he pleased.
"I will keep the memory of to-night in my heart of hearts," I said. "You shall never repent the trust you have reposed in me. May I come to you to-morrow? May I come as early as nine o'clock?"
"Yes, Walter," he replied, looking up at me kindly, and speaking in English once more, as if his one anxiety now was to get back to our former relations towards each other. "Come to my little bit of breakfast before I go my ways among the pupils that I teach."
"Good-night, my friend."
