"Well, then, if you obtain the reprieve?"

"The middle window at the Cafe Rospoli will be hung with white damask, bearing a red cross."

"And if you fail?"

"Then all three windows will have yellow draperies."

"And then?"

"And then, my good fellow, use your daggers in any way you please, and I further promise you to be there as a spectator of your prowess."

"We understand each other perfectly, then. Adieu, your excellency; depend upon me as firmly as I do upon you."

Saying these words, the Transteverin disappeared down the staircase, while his companion, muffling his features more closely than before in the folds of his mantle, passed almost close to Franz, and descended to the arena by an outward flight of steps. The next minute Franz heard himself called by Albert, who made the lofty building re-echo with the sound of his friend's name. Franz, however, did not obey the summons till he had satisfied himself that the two men whose conversation he had overheard were at a sufficient distance to prevent his encountering them in his descent. In ten minutes after the strangers had departed, Franz was on the road to the Piazza de Spagni, listening with studied indifference to the learned dissertation delivered by Albert, after the manner of Pliny and Calpurnius, touching the iron-pointed nets used to prevent the ferocious beasts from springing on the spectators. Franz let him proceed without interruption, and, in fact, did not hear what was said; he longed to be alone, and free to ponder over all that had occurred. One of the two men, whose mysterious meeting in the Colosseum he had so unintentionally unintentionally witnessed, was an entire stranger to him, but not so the other; and though Franz had been unable to distinguish his features, from his being either wrapped in his mantle or obscured by the shadow, the tones of his voice had made too powerful an impression on him the first time he had heard them for him ever again to forget them, hear them when or where he might. It was more especially when this man was speaking in a manner half jesting, half bitter, that Franz's ear recalled most vividly the deep sonorous, yet well-pitched voice that had addressed him in the grotto of Monte Cristo, and which he heard for the second time amid the darkness and ruined grandeur of the Colosseum. And the more he thought, the more entire was his conviction, that the person who wore the mantle was no other than his former host and entertainer, "Sinbad the Sailor."

Under any other circumstances, Franz would have found it impossible to resist his extreme curiosity to know more of so singular a personage, and with that intent have sought to renew their short acquaintance; but in the present instance, the confidential nature of the conversation he had overheard made him, with propriety, judge that his appearance at such a time would be anything but agreeable. As we have seen, therefore, he permitted his former host to retire without attempting a recognition, but fully promising himself a rich indemnity for his present forbearance should chance afford him another opportunity. In vain did Franz endeavor to forget the many perplexing thoughts which assailed him; in vain did he court the refreshment of sleep. Slumber refused to visit his eyelids and the night was passed in feverish contemplation of the chain of circumstances tending to prove the identity of the mysterious visitant to the Colosseum with the inhabitant of the grotto of Monte Cristo; and the more he thought, the firmer grew his opinion on the subject. Worn out at length, he fell asleep at daybreak, and did not awake till late. Like a genuine Frenchman, Albert had employed his time in arranging for the evening's diversion; he had sent to engage a box at the Teatro Argentino; and Franz, having a number of letters to write, relinquished the carriage to Albert for the whole of the day. At five o'clock Albert returned, delighted with his day's work; he had been occupied in leaving his letters of introduction, and had received in return more invitations to balls and routs than it would be possible for him to accept; besides this, he had seen (as he called it) all the remarkable sights at Rome. Yes, in a single day he had accomplished what his more serious-minded companion would have taken weeks to effect. Neither had he neglected to ascertain the name of the piece to be played that night at the Teatro Argentino, and also what performers appeared in it.

“There was her statement, Watson, and to me, as you can imagine, it was like a light on a dark night. Everything which had been disconnected before began at once to assume its true place, and I had a shadowy presentiment of the whole sequence of events. My next step obviously was to find the man who had produced such a remarkable impression upon Mrs. Barclay. If he were still in Aldershot it should not be a very difficult matter. There are not such a very great number of civilians, and a deformed man was sure to have attracted attention. I spent a day in the search, and by evening — this very evening, Watson — I had run him down. The man’s name is Henry Wood, and he lives in lodgings in this same street in which the ladies met him. He has only been five days in the place. In the character of a registration-agent I had a most interesting gossip with his landlady. The man is by trade a conjurer and performer, going round the canteens after nightfall, and giving a little entertainment at each. He carries some creature about with him in that box, about which the landlady seemed to be in considerable trepidation, for she had never seen an animal like it. He uses it in some of his tricks according to her account. So much the woman was able to tell me, and also that it was a wonder the man lived, seeing how twisted he was, and that he spoke in a strange tongue sometimes, and that for the last two nights she had heard him groaning and weeping in his bedroom. He was all right, as far as money went, but in his deposit he had given her what looked like a bad florin. She showed it to me, Watson, and it was an Indian rupee.

“So now, my dear fellow, you see exactly how we stand and why it is I want you. It is perfectly plain that after the ladies parted from this man he followed them at a distance, that he saw the quarrel between husband and wife through the window, that he rushed in, and that the creature which he carried in his box got loose. That is all very certain. But he is the only person in this world who can tell us exactly what happened in that room.”

“And you intend to ask him?”

“Most certainly — but in the presence of a witness.”

“And I am the witness?”

“If you will be so good. If he can clear the matter up, well and good. If he refuses, we have no alternative but to apply for a warrant.”

“But how do you know he’ll be there when we return?”

“You may be sure that I took some precautions. I have one of my Baker Street boys mounting guard over him who would stick to him like a burr, go where he might. We shall find him in Hudson Street to-morrow, Watson, and meanwhile I should be the criminal myself if I kept you out of bed any longer.”

It was midday when we found ourselves at the scene of the tragedy, and, under my companion’s guidance, we made our way at once to Hudson Street. In spite of his capacity for concealing his emotions, I could easily see that Holmes was in a state of suppressed excitement, while I was myself tingling with that half-sporting, half-intellectual pleasure which I invariably experienced when I associated myself with him in his investigations.
