Peter stopped when he saw her, and looked at her a little anxiously. 'You should not be standing, should you?' he said, in his kindly way; 'you look tired.'

Mrs. Ogilvie gave one of her enigmatic smiles. 'Who would not be tired?' she said. 'Was there ever such an extraordinary way of amusing oneself as to stand in a draughty doorway in the middle of the night, shaking hands with some hundreds of people whom one doesn't want to see!'

She sat down on a sofa and watched the two figures as they passed down the long corridor. The mechanical smile of welcome with which she had greeted half the county this evening had not died away from her face; she sat upright on the satin-covered sofa. There was about her an air of strength, of eminence almost, which seemed to place her genuine ugliness above criticism. Her dress was of some heavy purple stuff which few women would have had the courage to wear, and the diamonds in her hair, with their sharp points of radiating light, accentuated something that was magnificent and almost defiant about Mrs. Ogilvie to-night. Her short-sighted eyes contracted in their usual fashion as she watched the couple disappear down the vista of the corridor. 'If only it could be soon! If only their marriage could be soon!' she murmured to herself, her lips moving in an inward cry that in another woman might have been a prayer.

'How do you think she is looking?' said Peter, as, without conscious intention, he and Jane drifted away from the dancers into a more distant part of the house. 'Surely she gets tired too easily? I wish she would see a doctor; but she hates being fussed over, and one can never persuade her to take care of herself.'

'What is one to do with so wilful a woman?' said Jane.

They paused and looked at the dim crowd of dancers through one of the entrances to the ballroom, and passed down the corridor where misty figures sat on sofas and chairs enjoying the cool. Every one looked to them misty and far away to-night, almost as though they had not sufficiently materialized to be perfectly distinct.

With definite intention Peter led his partner towards a little room, hung with miniatures and plaques, at the farther end of the long corridor. Here they found Nigel Christopherson in conversation with Miss Sherard. Kitty was talking as lightly as usual, deliberately misunderstanding everything that was said to her, and being as provoking as she ever was; and Toffy was so much in earnest that he did not see Peter and Jane, but continued to talk to the girl beside him. So the two intruders never entered the room at all; but, as they pursued their way still farther, Peter was thinking about Mrs. Avory, and wishing to goodness that Toffy had never met her.

The big house seemed too full of people for his taste to-night. Every room and corridor was occupied, and Peter said, 'Let's go to my mother's sitting-room. Do you mind, Jane? We can get cool on the bridge.'

Bowshott is a very old house, so old that, if it had not been for archaeologists, who came there sometimes and read the grey stones as though they had been printed paper, no one would ever have known when the earliest part of it was built. Antiquaries agreed that it dated from Norman days; but the only portion of the building of that period which was standing now was a tower at the eastward end of the house. It had been almost in ruins at one time, but Colonel Ogilvie's father had restored it, and, with a considerable amount of skill, had connected it with the more modern part of the house by a stone bridge on a single arch. The whole thing was excellently contrived; the archway lent a frame to one of the most beautiful parts of the garden; and the tower, which was entered by a strong oak door from the bridge, now contained three curious, romantic-looking rooms, with quaint, uneven walls six feet thick, deep, narrow windows, and heavy oak ceilings. The largest of the rooms to which admittance was gained by the oak door was Mrs. Ogilvie's sitting-room. She had a curious love of being alone for hours at a time, and she enjoyed the sense of isolation which was afforded her by being cut off from the rest of the building by the stone bridge on its high arch. Here she would spend whole days by herself, reading or writing. Above this room, which was full of her own particular possessions, was a smaller apartment containing a valuable library of philosophical works. Here were muniment-chests, and the large writing-table where she wrote all the business letters relating to the estate; and here it was that she was wont to see her steward and her agent from time to time. No one but Mrs. Ogilvie and her son ever entered the room without some special reason, and it was too far away from the rest of the house for casual visitors to intrude themselves. The short passage, within the more modern house, which led to the bridge was reached by a door hung with a leather curtain securely arranged to prevent draughts, and no one ever lifted this curtain except those who had a right to the rooms beyond.

To-night, however, the house was open to all comers, and it afforded no surprise to Captain Ogilvie and his companion, when they had quitted the corridor and the reception-rooms, and had left the guests and servants behind them, to find a man's figure before them in the short passage leading to the leather-covered door.
