“Nay, there is no need of haste, for you cannot start until we are two miles upon our way. And above all I pray you, Nigel, none of your knight-errant ways. It is this roan that I want, him and the news that he can bring me. Think little of your own advancement and much of the needs of the army. When you get him, ride westwards upon the sun, and you cannot fail to find the road.”

Nigel waited with Pommers under the shadow of the nunnery wall, horse and man chafing with impatience, whilst above them six round-eyed innocent nun-faces looked down on this strange and disturbing vision from the outer world. At last the long column wound itself out of sight round a curve of the road, and the white dot was gone from the bare green flank of the hill. Nigel bowed his steel head to the nuns, gave his bridle a shake, and bounded off upon his welcome mission. The round-eyed sisters saw yellow horse and twinkling man sweep round the skirt of the wood, caught a last glimmer of him through the tree-trunks, and paced slowly back to their pruning and their planting, their minds filled with the beauty and the terror of that outer world beyond the high gray lichen-mottled wall.

Everything fell out even as Knolles had planned. As Nigel rounded the oak forest, there upon the farther side of it, with only good greensward between, was the rider upon the white horse. Already he was so near that Nigel could see him clearly, a young cavalier, proud in his bearing, clad in purple silk tunic with a red curling feather in his low black cap. He wore no armor, but his sword gleamed at his side. He rode easily and carelessly, as one who cares for no man, and his eyes were forever fixed upon the English soldiers on the road. So intent was he upon them that he gave no thought to his own safety, and it was only when the low thunder of the great horse’s hoofs broke upon his ears that he turned in his saddle, looked very coolly and steadily at Nigel, then gave his own bridle a shake and darted off, swift as a hawk, toward the hills upon the left.

Pommers had met his match that day. The white horse, two parts Arab, bore the lighter weight, since Nigel was clad in full armor. For five miles over the open neither gained a hundred yards upon the other. They had topped the hill and flew down the farther side, the stranger continually turning in his saddle to have a look at his pursuer. There was no panic in his flight, but rather the amused rivalry with which a good horseman who is proud of his mount contends with one who has challenged him. Below the hill was a marshy plain, studded with great Druidic stones, some prostrate, some erect, some bearing others across their tops like the huge doors of some vanished building. A path ran through the marsh with green rushes as a danger signal on either side of it. Across this path many of the huge stones were lying, but the white horse cleared them in its stride and Pommers followed close upon his heels. Then came a mile of soft ground where the lighter weight again drew to the front, but it ended in a dry upland and once again Nigel gained. A sunken road crossed it, but the white cleared it with a mighty spring, and again the yellow followed. Two small hills lay before them with a narrow gorge of deep bushes between. Nigel saw the white horse bounding chest-deep amid the underwood.

Next instant its hind legs were high in the air, and the rider had been shot from its back. A howl of triumph rose from amidst the bushes, and a dozen wild figures armed with club and with spear, rushed upon the prostrate man.

À moi, Anglais, à moi!” cried a voice, and Nigel saw the young rider stagger to his feet, strike round him with his sword, and then fall once more before the rush of his assailants.

There was a comradeship among men of gentle blood and bearing which banded them together against all ruffianly or unchivalrous attack. These rude fellows were no soldiers. Their dress and arms, their uncouth cries and wild assault, marked them as banditti—such men as had slain the Englishman upon the road. Waiting in narrow gorges with a hidden rope across the path, they watched for the lonely horseman as a fowler waits by his bird-trap, trusting that they could overthrow the steed and then slay the rider ere he had recovered from his fall.

Such would have been the fate of the stranger, as of so many cavaliers before him, had Nigel not chanced to be close upon his heels. In an instant Pommers had burst through the group who struck at the prostrate man, and in another two of the robbers had fallen before Nigel’s sword. A spear rang on his breastplate, but one blow shore off its head, and a second that of him who held it. In vain they thrust at the steel-girt man. His sword played round them like lightning, and the fierce horse ramped and swooped above them with pawing iron-shod hoofs and eyes of fire. With cries and shrieks they flew off to right and left amidst the bushes, springing over boulders and darting under branches where no horseman could follow them. The foul crew had gone as swiftly and suddenly as it had come, and save for four ragged figures littered amongst the trampled bushes, no sign remaining of their passing.

Nigel tethered Pommers to a thorn-bush and then turned his attention to the injured man. The white horse had regained his feet and stood whinnying gently as he looked down on his prostrate master. A heavy blow, half broken by his sword, had beaten him down and left a great raw bruise upon his forehead. But a stream gurgled through the gorge, and a capful of water dashed over his face brought the senses back to the injured man. He was a mere stripling, with the delicate features of a woman, and a pair of great violet-blue eyes which looked up presently with a puzzled stare into Nigel’s face.

“Who are you?” he asked. “Ah yes! I call you to mind. You are the young Englishman who chased me on the great yellow horse. By our Lady of Rocamadour whose vernicle is round my neck! I could not have believed that any horse could have kept at the heels of Charlemagne so long. But I will wager you a hundred crowns, Englishman, that I lead you over a five-mile course.”
