She scarcely knew what it was that she raged against as slowly, methodically, she began to undress. The little brilliant or paste brooch, she knew not which, formed of two crossed p's which was the only relic she possessed of her dead father, arrested her for a second. What sort of a man had he been really, she wondered, and what sort of a son would hers be when she had one? She flung the tiny bauble from her impatiently, so stood for a second drawn up to her full height, her bare arms crossed, her shapely hands clasping their smooth roundness; then, with a sudden sob, she realised what had come to her, and, throwing herself face downwards on her bed, lay for a minute or two still as the dead. Then as suddenly she sat up again with a world of puzzled wonder in her strained eyes. "I canna think," she murmured, "what gars' me love him so, but I do, and there's an end o' it." Possibly; but such knowledge as that which had just burst over her like a storm does not make for quiet sleep. She told herself a thousand and one wise things, but the hours slipped by, bringing at last a conviction of hopelessness. She would be better up than pretending to rest, so she went to stand at the window once more. The flush of coming day was clear now in the northeast, the flood-tide of the full moon lay mysterious in the embrace of the rocks. Ere long the rising sun would send battalions on battalions of shining golden ripples to storm the estuary and climb the shadowy cliff on which the castle stood--where he lay drunk! Ah, well! That would not spoil the beauty of it all, which she had so often seen, and the nip of the salt North Sea might check her silly desire for him. The room felt stifling; she would be better outside. So, slipping on her swimming-dress of coarse white flannel blanketing (for ever since those childish days when she and Duke had done everything in common she had been an expert swimmer), she threw a plaid round her, and made her way through the keep gateway to the rocks below. There was no breeze, the tide must be at its height almost, and there was the spent moon, pale with its long night-watch, hanging on the grey sky of dawn. Ah, these were the things worth having--the others could be set aside with joy! Ere five minutes were over, breathless from her fierce driving strokes through the water, she had turned over on her back, and, face to the skies, was trying to imagine she was floating thitherwards. The gulls, wakened by the coming light, skimmed over her in their quest for food. The little pointed wavelets that rose and fell, marking the course of the river stream, made a fine, sobbing, tinkling noise in her ears. Full flood-tide!
