They were eyes not easy to forget, especially as they blazed defiance into those of the men who sprang forward to lay hands upon him. "There stands the murderer, gentlemen, as you see," he had said, making a gesture towards his young companion, a boy of eighteen or nineteen, who seemed too astonished and horrified to move. Despite the evidence of the fallen knife, however, not one among the men who witnessed the end of the scene believed that the youth was guilty. Murder was in the eyes of the other, and must have betrayed him, even if the last words of the dead man had not accused him.

California was somewhat wilder in those days than it is at present, and men were more ready to act upon impulse. So it was that, as two of us gripped the fierce, red-haired fellow, another of the party flung some whispered word to the boy, who had only spoken to murmur brokenly, "God knows I'm innocent!"

What that whispered word was no one knew save he who spoke it and he to whom it was addressed. But whatever it might have been, it seemed to rouse the young man to life and a realisation of his position. With a leap he was at the long window and had sprung out on to a verandah, which ran round three sides and three stories of the house. The room was on the first floor, and it was easy enough for an active young fellow to let himself down by one of the twisted pillars which supported the verandah of the lower storey.

It could not have been so easy to escape those who half-heartedly followed; but the boy must have found some safe sanctuary near by, for not only did he evade his pursuers, but was never found or brought to trial.

The other, an Australian, calling himself Willis Collins, known as a gambler, suspected as a card "sharper," was less fortunate. But for the cry of the dying man he might have cleared himself; but his reputation was against him to begin with; it was proved that the other was a young Englishman who had lost his money through Collins, and been duped by him, and altogether matters went hardly with the elder of the two confederates. He was tried and condemned (not for murder, as it happened, but manslaughter), and sentenced to imprisonment for twenty years.

The incident had passed out my mind until, on a visit to America six years later (four years previous to my present one), a man who had been of our bear-shooting party in the Rocky Mountains had chanced to mention that the fellow had very cleverly succeeded in making his escape from the prison where he had been confined.

I had had no personal interest in the affair, and though it had made considerable impression upon me at that time, through being called up at the trial as a witness, I do not suppose I had summoned it to my recollection for many a long day until now, at the mention of the Santa Anna Hotel.

It was no wonder, I told myself, that I had not been able to decide where and how I had seen Carson Wildred previous to the night when Farnham had introduced us to each other at the theatre. Unless I could collect proofs not at present in my possession, it would even now be useless to instill my conviction into the mind of anyone else.

Carson Wildred had a peculiarly flat nose; Willis Collins had had a particularly high one. Carson Wildred's hair was inky black; Willis Collins's had been a bright auburn. Wildred's face was smooth; Collins's mouth and chin had been concealed by a heavy though close-cropped red beard. So far as I knew there was but one man living who could have effected so radical a change, not only in the appearance, but in the actual conformation of features, in the countenance of any human being, and that was an old fellow in Paris, who had gained a reputation and a fortune among men who had reason to cut loose from the moorings of their past. I had met this famous (or infamous) person in a curious way, and had heard some strange stories from his lips. If I had made his acquaintance, why should not Collins or Wildred have done so and profited by the friendship, as fortunately I had neither the desire nor need to do? I determined that, unless my present researches were more successful than I now dared expect them to be, I would, on my return to the other side, run across to France, and endeavour to piece together the bits of this old but newly-discovered puzzle.

Meanwhile, however, I had other work, and work closer at hand.
