“I am Isabel Culbridge,” she told him, watching his face.

“Lady Isabel?” Francis repeated incredulously. “But surely—”

“Better not contradict me,” she interrupted. “Look again.”

Francis looked again.

“I am very sorry,” he said. “It is some time, is it not, since we met?”

She stood by his side, and for a few moments neither of them spoke. The little orchestra in the bows had commenced to play softly, but there was none of the merriment amongst the handful of men and women generally associated with a midnight river picnic. The moon was temporarily obscured, and it seemed as though some artist's hand had so dealt with the few electric lights that the men, with their pale faces and white shirt-fronts, and the three or four women, most of them, as it happened, wearing black, were like some ghostly figures in some sombre procession. Only the music kept up the pretence that this was in any way an ordinary excursion. Amongst the human element there was an air of tenseness which seemed rather to increase as they passed into the shadowy reaches of the river.

“You have been ill, I am afraid?” Francis said tentatively.

“If you will,” she answered, “but my illness is of the soul. I have become one of a type,” she went on, “of which you will find many examples here. We started life thinking that it was clever to despise the conventional and the known and to seek always for the daring and the unknown. New experiences were what we craved for. I married a wonderful husband. I broke his heart and still looked for new things. I had a daughter of whom I was fond—she ran away with my chauffeur and left me; a son whom I adored, and he was killed in the war; a lover who told me that he worshipped me, who spent every penny I had and made me the laughing-stock of town. I am still looking for new things.”

“Sir Timothy's parties are generally supposed to provide them,” Francis observed.

The woman shrugged her shoulders.
