Fortunately for everyone's peace of mind, the Congreves, being unable to leave London until late on Christmas Eve, were also unable to play the part of kill-joys at Baba's Christmas-tree, and the little party which assembled in the big hall of the Castle, was composed of congenial and friendly folk, who were ready to become little children again, to play with a little child.

The hall, oak-panelled, and hung with suits of armour, and weapons handed down from war-like Redesdale ancestors, had long since been converted into a luxurious lounge, where, if comfortably upholstered chairs, big palms, masses of flowers, and tables strewn with the latest books, were incongruities, the incongruity at least made the hall a most pleasant and sociable sitting-room. And so Fergusson thought it, when from the sharpness of the grey winter day, he passed through an outer vestibule, into the well-warmed, well-lighted place. Only he himself knew with what an unaccountable sinking of the heart he had driven up the beech avenue leading to the Castle, and realised what an imposing place it was, to which he had been bidden. Involuntarily, and in sharp contrast, the thought of his own modest house rose before his mental vision, and the usually cheery doctor, for perhaps the first time in his disciplined and philosophical existence, felt disposed to curse the Fates, for dividing rich and poor by gulfs of such appalling dimensions. But that sinking of the heart, and all the other unwonted sentiments stirred in him by the sight of the great pile of Bramwell, its stately park and lordly surroundings, were swept away by the cordial greeting bestowed upon him, by the little lady of the house, and by Baba's enthusiastic welcome.

"Baba's doctor man," the child cried, with a small shriek of delight when he appeared, and Baba monopolised her doctor man during the whole two hours he was able to spend with them. But if to the larger number of the party assembled in the hall, Fergusson seemed to have neither eyes nor ears for anyone but the child-queen of the occasion, Christina's observant eyes told her that his glance often rested upon Cicely's fair head, and that whenever it did so, a great tenderness crept into that glance. As she had told Lady Cicely, the rough school in which her life had lately been spent, had taught her to study and understand her fellow beings, and the doctor's secret, unknown to himself, was shared by Christina, on that happy Christmas Eve. She was a very safe and discreet guardian of secrets, this girl with the sweet eyes, but she gave a quick little sigh when she understood the meaning of Fergusson's glance, for to her, as to himself, there seemed an unbridgeable gulf, between the hard-working doctor, and the dainty châtelaine of Bramwell Castle. Before he left, Fergusson contrived to make his way to Christina's side, and to say in an undertone:—

"I think you will be sorry to know that your beautiful lady of the lonely valley is in great trouble."

"Oh!" Christina exclaimed softly, her eyes darkening; "has the end come for him?"

"Yes, five days ago. She is wonderful, but the heart-break in her eyes is pitiful to see. I sometimes doubt whether her strength will hold out; she is very fragile, and all the strain has told on her more than I like."

"Was he buried at——" Christina was beginning, when Fergusson finished the sentence quickly.

"No, not at Graystone. I don't know where she took him, but it was away from that part of the country altogether. She and her faithful Elizabeth went with him, and now she is back in that lonely house again. I have tried to persuade her to leave it—to go to London—to go anywhere away—but she answers me she is happier there, and I cannot oppose her. But it is all a tragedy, an inexplicable tragedy."

He could say no more, but what he had told Christina, filled the girl's heart with sadness; her beautiful lady had made a profound impression upon her, and the thought of the sorrowful woman in that lonely house in the valley, hurt the girl's tender soul.

"I am glad we asked Dr. Fergusson," Cicely said to her, when later on in the evening the two were alone together in Baba's day nursery; "there is something so cheering about him, something," she added, with a wistful look into Christina's face, "that makes me think of my husband."
