It was his last word. The keen long knife had passed from her hands to des Ageaux', from her weak fingers to his practised grip. As the man who held her paused to peer before him--for the ford, shadowed by spreading trees, was dark as pitch--des Ageaux drove the point straight and sure into the throat above the collar-bone. The action was so sudden, so unexpected, that the man he struck had no time to cry out, but with a low gurgling moan fell forward on his burden.
His comrade who rode before the Lieutenant knew little more. Before he could turn, almost before he could give the alarm, the weapon was driven in between his shoulders, and the Lieutenant, availing himself of the purchase which his bound feet gave him, hurled him over the horse's head. Unfortunately the man had time to utter one shriek, and the cry with the splash, and the plunging of the terrified horse, bore the alarm to his comrades on the bank.
"What is it? What is the matter?" a voice asked. And a score of feet could be heard pounding hurriedly along the bank.
The Lieutenant had one moment only in which to make his choice. If he remained on the horse, which he could not restrain, for the reins had fallen, he might escape, but the girl must perish. He did not hesitate. As the frightened horse reared he cut his feet loose, and slid from it. He made one clutch at the floating reins but missed them. Before he could make a second the terrified animal was on the bank.
There remained the girl's horse. But Bonne, drenched by the dying man's blood, had flung herself off--somehow, anyhow, in irrepressible horror. As des Ageaux turned she rose, dripping and panting beside him, her nerve quite gone. "Oh, oh!" she cried. "Save me! Save me!" and she clung to him.
Alas, while she clung to him her horse floundered out of the stream, and trotted after its fellow.
The pursuers were no more than thirty yards away, and but for the deep shadow which lay on the ford must have seen them. The Lieutenant had no time to think. He caught the girl up, and as quickly as he could he waded with her to the bank from which they had entered the water. Once on dry land he set her on her feet, seized her wrist and gripped it firmly.
"Courage!" he said. "We must run! Run for your life, and if we can reach the wind-mill we may escape!"
He spoke harshly, but his words had the effect he intended. She straightened herself, caught up her wet skirt and set off with him across the road and up the bare hill-side. He knew that not far above them stood a wind-mill with a narrow doorway in which one man might make some defence against numbers. The chance was slight, the hope desperate; but he could see no other. Already the pursuers were splashing through the ford and scattering on the trail, some running up the stream, some down, some stooping cunningly to listen. To remain beside the water was to be hunted as otters are hunted.
His plan answered well at first. For a few precious instants their line of retreat escaped detection. They even increased their start, and had put fifty or sixty yards of slippery hill-side between themselves and danger before a man of sharper ears than his fellows caught the sound of a stone rolling down the slope, and drew the hue and cry in the right direction. By that time the dark form of the wind-mill was faintly visible sixty or eighty yards above the fugitives. And the race was not ill set.
