“You promised faithfully to be there,” he said slowly. “I loathe afternoon concerts, and——”

She was really like her sister he thought, impressed for a moment by the soft brilliancy of her smile. Her fingers rested upon his.

“You were really at Moulton House,” she exclaimed penitently. “I am so sorry. I had a perfect shoal of callers. People who would not go. I only arrived when everybody was coming away.”

A little murmur of expectation, an audible silence announced the coming of “Alcide.” Then a burst of applause. She was standing there, smiling at the audience as at her friends. From the first there had always been between her and her listeners that electrical sympathy which only a certain order of genius seems able to create. Then she sang.

Ennison listened, and his eyes glowed. Lady Ferringhall listened, and her cheeks grew pale. Her whole face stiffened with suppressed anger. She forgot Anna’s sacrifices, forgot her own callousness, forgot the burden which she had fastened upon her sister’s shoulders. She was fiercely and bitterly jealous. Anna was singing as she used to sing. She was chic, distinguished, unusual. What right had she to call herself “Alcide”? It was abominable, an imposture. Ennison listened, and he forgot where he was. He forgot Annabel’s idle attempts at love-making, all the cul-de-sac gallantry of the moment. The cultivated indifference, which was part of the armour of his little world fell away from him. He leaned forward, and looked into the eyes of the woman he loved, and it seemed to him that she sang back to him with a sudden note of something like passion breaking here and there through the gay mocking words which flowed with such effortless and seductive music from her lips.

Neither of them joined in the applause which followed upon her exit. They were both conscious, however, that something had intervened between them. Their conversation became stilted. A spot of colour, brighter than any rouge, burned on her cheeks.

“She is marvellously clever,” he said.

“She appears to be very popular here,” she remarked.

“You too sing?” he asked.
