He soon realized that the remaining distance was all too short. As he came to the place where the forest abruptly terminated, he saw that day had broken. The gray light showed him to be still thirty yards or so behind.

They had reached the broken lands he remembered so well. Before him stretched the plateau leading to the convergence of the river and the cliff. It was the sight of this which gave him an inspiration. He remembered the branching trail to the bridge, also the wide sweep it took, as compared with the way he had first come. To leap the river would gain him fifty yards. But in that light it was a risk—a grave risk. He hesitated. Annoyed at his own indecision, he determined to risk everything on one throw. The other horse was distinctly lagging. He reached down and patted his mare’s neck. And that simple action restored his confidence; he felt that she was still on top of her work. The river would have no terrors for her.

He saw the masked man turn off for the bridge, but he held straight on. He gave another anxious look at the sky. The dull gray was still unbroken by any flush of sunrise, but it was lighter, certainly. The mask of clouds was breaking, though it still contrived to keep daylight in abeyance. He had no option but to settle himself in the saddle for the great effort. Light or no light, he could not turn back now.

And for the while he forgot the fugitive. His mind centred on the river ahead, and the moment when his hand must lend the mare that aid, without which he could not hope, after her great journey, to win the far bank. His nerve was steady, and his eyes never more alert. Everything was distinct enough about him. The bushes flying by were clearly outlined now, and he fancied he could already see the river’s line of demarkation. On they raced, he leaning well forward, she with her ears pricked, attentive to the murmurs of the water already so near. Unconsciously his knees gripped the leggaderos of his saddle with all the power he could put into the pressure, and his body was bent crouching, as though he were about to make the spring himself.

And the moment came. He spurred and lifted; and the game beast shot forward like a rocket. A moment, and she landed. But the half lights must have deceived her. She had jumped further than before, and, crashing into a boulder with her two fore feet, she turned a complete somersault, and fell headlong to the ground, hurling her rider yards out of the saddle into the soft loose sand of the trail beyond.

Quite unhurt, Tresler was on his feet in an instant. But the mare lay still where she had fallen. A hopeless feeling of regret swept over the man as he turned and beheld her. He saw the masked rider dash at the hillside on his weary horse, not twenty yards from him, but he gave him no heed.

It needed no look into the mare’s glazing eyes to tell him what he had done. He had killed her. The first really honest act of her life had led to the unfortunate creature’s own undoing. Her lean ewe neck was broken, as were both her forelegs.

The moment he had ascertained the truth he left her, and, looking up at the hill, saw that it was high time. The rider had vanished, but his jaded horse was standing half-way up the hillside in the mire of loose sand. It was either too frightened or too weary to move, and stood there knee-deep, a picture of dejection.

The task of mounting to the ledge was no light one, but Tresler faced it without a second thought. The other had only something less than a minute’s start of him, and as there was only one other exit to the place—and that, he remembered, of a very unpromising nature—he had few fears of the man’s ultimate escape. No, there was no escape for him; and besides—a smile lit up the hard set of his features at the thought—daylight had really come. The clouds had at last given way before the rosy herald of sunrise.
