The children found their grandfather in the oriel room, so called because of the great oriel window, which was a small room in itself, although it looked, as you approached the castle, no bigger than a swallow's nest on the face of the solid masonry, being the only excrescence visible above the trees from that point of view. The castle stood on a hill which descended precipitously from under the oriel, so that the latter almost overhung the valley in which the city lay below, and commanded a magnificent view of the flat country beyond, thridded by a shining winding ribbon of river. The hill was wooded on that side to the top, and the castle crowned it, rising above the trees in irregular outline against the sky imposingly. The old duke sat in the oriel often, looking down at the wonderful prospect, but thinking less of his own vast possessions than of the great cathedral of Morningquest, which he coveted for Holy Church. He had become a convert to Roman Catholicism in his old age, and his bigotry and credulity were as great now as his laxity and scepticism had been before his conversion. He was sitting alone with his confessor and private chaplain, Father Ricardo, a man of middle age, middle height, attenuated form, round head with coarse black hair, piercing dark eyes, aquiline nose somewhat thick, and the loose mouth characteristic of devout Roman Catholics, High Church people, and others who are continually being wound up to worship an unseen Deity by means of sensuous enjoyment; the uncertain lines into which the lips fall in repose indicating fairly the habitual extent of their emotional indulgences. His manners were suave and deferential, his motives sincerely disinterested in the interests of the Church, his method of gaining his ends unhampered by any sense of the need of extreme verbal accuracy. He was reading to the duke when the children were announced, and rose and bowed low to them as they entered, with a smile of respectful and affectionate interest. Diavolo raised his dusty cap to his chest and returned the bow with punctilious gravity. Angelica tossed him a nod as she passed up the room in a business-like way to where her grandfather was sitting facing the window. The old duke looked round as the children approached and his face relaxed; he did not absolutely smile, but his eyes twinkled.
