“The rooms are so hot,” answered Barbara shortly. “How do you do, Dr. Tarbot?”

The man held out his hand, which Barbara just touched with her long, slim fingers. His was a somewhat striking personality, and yet he was not the least good-looking. He was of medium height, thin in build: his brow was broad and lofty, his eyebrows well marked, and his deep gray eyes were full of light.

That strange light was never absent from the eyes, which in themselves were somewhat pale in color, but with their black irises and black surroundings made an important addition to a decidedly remarkable face. The man’s mouth was firm and cut in a straight line.

He made the most of his height, holding himself very erect, and now he looked full and boldly into Barbara’s eyes. The balcony was softly lit, and the girl could be seen quite distinctly. The electric light, which was covered with glass globes formed in the shape of lilies, gave her an unreal appearance.

“I am glad I have found you,” repeated Tarbot. He spoke in a hurry, and as though he were slightly out of breath. “I rushed off here in great haste. I must see a patient again before midnight. The man will probably die when the new day dawns, and he has a longing to have me with him when he breathes his last.”

Barbara was silent, but her eyes, as if mesmerized, fixed themselves on Tarbot.

“It is a relief to see you, Miss Evershed: you look so bright—as if you had never known sorrow or illness. The contrast between that dying man’s agony and your grace and beauty is enough to stagger one. Yes, I can stay but for a quarter of an hour. I promised Mr. Harlington to be with him when he died.”

“Why did you leave him?” said Barbara in her slow voice. She always spoke in a slow, reflective sort of way.

“Does not the contrast make you ill?” she continued. “The frivolity of life one moment, a death-bed the next. I do not know how you doctors can live; you must get terribly hard as the years go on. Well, I must go back to our guests; mother will want me to help her. There are a great many people here to-night.”

“The rooms are packed and the heat is stifling. Why should you join that overheated throng? As to your mother wanting you, she told me where I should find you, and said nothing about asking you to go to her. Please stay——”
