IV
THE MAN ON HORSEBACK

Gavan of the Greenwood Keep was a prosperous man according to the standard of these latter days, and his estate was reckoned to be the largest and finest holding in all the western country-side. A man might walk from break of day until darkness and yet not complete the periphery of its boundary-lines, but the palisaded portion included only the arable land and home paddocks and was of comparatively limited extent. Viewed from a bird's-eye elevation, this stockaded enclosure appeared to be laid out in the shape of a pear, the house being situated near the small end. The greatest length of the area thus enclosed was a mile and a half, and it was three-quarters of a mile wide at the big or southern side, tapering down to a couple of hundred yards at the northern entrance or barrier.

A quarter of a mile back from the north gate stood the keep, not one distinct building, but rather several, built in the form of a hollow square and consolidated for mutual protection. The principal entrance, the one at the northern end, was called the water gate, for it should be explained that the keep stood on the bank of the Ochre brook and access was only possible by means of a drawbridge. Some day Sir Gavan intended to turn the course of the stream so as to carry it around the keep and thereby secure the protection of a continuous moat. But hitherto other duties had seemed more pressing, and the plan was still in abeyance.

Entering through the covered way of the water gate, with guard-room and bailiff's office to the right and left, one found himself in the court-yard, some fifty yards in the square. On the right were the cow-barns, horse-stalls, granaries, tool-houses, and store-buildings, while the dwelling proper, known as the Great House, occupied the entire left of the square, the kitchens and other offices adjoining the retainers' quarters on the south. An enormous hall, running clear to the roof, took up the central portion of the house, staircases and galleries affording access to the store and sleeping-rooms on the second and attic stories. The roof proper was surmounted by a para-petted and loop-holed structure called the fighting platform, and it was thither that Constans had repaired upon receiving the startling intelligence of his sister's disappearance. Let us rejoin him there.

In the leisurely moving figure glimpsed through the birches, Constans had instantly recognized Issa. Plainly she had been out flower-hunting; with the aid of his binoculars he could determine that she carried a bunch of the delicate pink-and-white blossoms that we call May-bloom. She was directing her steps straight for the house, but either she was unaccountably deaf to the continuous clanging of the alarm-bell or, still more strangely, unaware of its significance; she walked as though in a reverie, slowly and with her head bent forward. Thunder of God! it was a trap, and the foolish girl would not see. Unquestionably, the Doomsmen had forced the stockade at some distant point and were even now in ambush about the keep. But Constans, for all his keenness of vision and the assistance of his glass, could discover nothing to indicate the presence of any considerable body of men. There was no one in actual sight save he who sat upon his blood-bay steed, girth deep in the Ochre brook under shadow of the alders. Only one, but that one!

Constans found himself in the court-yard; how he scarcely knew. The water gate still stood open with the drawbridge lowered, but both could be easily secured within a few seconds should the enemy venture upon any open demonstration. Sir Gavan stood in the covered way talking anxiously with his eldest son Tennant, who had just returned from an unsuccessful search of the upper orchard.

Constans, in his confusion of mind, did not notice his father and brother; he ran across the court-yard to the horse-boxes. His black mare Night whickered upon recognizing her master, and tried to rub her muzzle against his cheek as he fumbled with the throat-latch of the bridle. An instant longer, to lead out the mare and vault upon her back, and he was clattering through the court-yard and covered way.

Upon reaching the open Constans saw that the situation had developed into a crisis. The cavalier of the ostrich-feather had forced his horse up the steep bank of the Ochre brook and was riding slowly towards the girl, who stood motionless, realizing her perilous position, but unable for the moment to cope with it. She half turned, as though to seek again the shelter of the birchen copse; then, clutching at her impeding skirts, she ran in the direction of the keep. He of the ostrich-plume spurred to the gallop; inevitably their paths must intersect a few yards farther on.
