‘Come along, then,’ said I. ‘I can see nothing in this rat hole.’

Suddenly, from in front of us, a cry rang out; it was some distance off. We started towards it, for it was Kortes’s voice that cried.

‘Be careful, be careful,’ urged Phroso. ‘We’re near the bridge now.’

It was true. As she spoke the walls of rock on either side receded. We had come to the opening. The dark water was below us, and before us the isolated bridge of rock that spanned the pool. We were where the Lord of the island had been wont to hurl his enemies headlong from his side to death.

What happened on the bridge, on the narrow bridge of rock which ran in front of us, we could not see; but from it came strange sounds, low oaths and mutterings, the scraping of men’s limbs and the rasping of cloth on the rock, the hard breathings of struggling combatants; now a fierce low cry of triumph, a disappointed curse, a desperate groan, the silence that marked a culminating effort. Now, straining my eyes to the uttermost, and having grown a little more accustomed to the darkness, I discerned, beyond the centre of the bridge, a coiling writhing mass that seemed some one many-limbed animal, but was, in truth, two men, twisted and turned round about one another in an embrace which could have no end save death. Which was Kortes, which Constantine, I could not tell. How they came there I could not tell. I dared not fire. Phroso hung about me in a paroxysm of fear, her hands holding me motionless; I myself was awed and fascinated by the dim spectacle and the confused sounds of that mortal strife.

Backward and forward, to and fro, up and down they writhed and rolled. Now they hung, a protrusion of deeper blackness, over the black gulf on this side, now on that. Now the mass separated a little as one pressed the other downward and seemed about to hurl his enemy over and himself remain triumphant; now that one, in his turn, tottered on the edge as if to fall and leave the other panting on the bridge; again they were mixed together, so that I could not tell which was which, and the strange appearance of a single, writhing, crawling shape returned. Then suddenly, from both at once, rang out cries: there was dread and surprise in one, fierce, uncalculating, self-forgetful triumph in the other. Not even for Phroso’s sake, or the band of her encircling arms, could I rest longer. Roughly I fear, at least with suddenness, I disengaged myself from her grasp. She cried out in protest and in fear, ‘Don’t go, don’t leave me!’ I could not rest. Recollecting the peril, I yet rushed quickly on to the bridge, and moved warily along its narrow perilous way. But even as I came near the two who fought in the middle, there was a deep groan, a second wild triumphant cry, a great lurch of the mass, a moment—a short short moment—when it hung poised over the yawning vault; and then an instant of utter stillness. I waited as a boy waits to hear the stone he has thrown strike the water at the bottom of the well. The stone struck the water: there was a great resounding splash, the water moved beneath the blow; I saw its dark gleam agitated. Then all was still again; and the passage of the bridge was clear.

I walked to the spot where the struggle had been, and whence the two had fallen together. I knelt down and gazed into the chasm. Three times I called Kortes’s name. No answer came up. I could discern no movement of the dark waters. They had sunk, the two together, and neither rose. Perhaps both were wounded to death, perhaps only their fatal embrace prevented all effort for life. I could see nothing and hear nothing. My heart was heavy for Kortes, a brave true man and our only friend. In the death of Constantine I saw less than his fitting punishment; yet I was glad that he was gone, and the long line of his villainies closed. This last attempt had been a bold one. Mouraki, no doubt, had forced him to it; even a craven will be bold where the penalty of cowardice is death. Yet he had not dared to stand when discovered. He had fled, and must have been flying when Kortes came up and grappled with him. For a snapshot at an unwary man he had found courage, but not for a fair fight. He was an utter coward after all. He was well dead, and his wife well avenged.

But it was fatal to linger here. Mouraki would be expecting the return of his emissary. I saw now clearly that the Pasha had prepared the way for Constantine’s attempt. If no news came, he would not wait long. I put my reflections behind me and walked briskly back to where I had left Phroso. I found her lying on the ground; she seemed to be in a faint. Setting my face close to hers, I saw that her eyes were shut and her lips parted. I sat down by her in the narrow passage and supported her head on my arm. Then I took out a flask, and pouring some of the brandy-and-water it contained into the cup forced a little between her lips. With a heavy sigh she opened her eyes and shuddered.

‘It is over,’ I said. ‘There’s no need to be afraid; all is over now.’

‘Constantine?’
