"Why didn't you come with your story then?"

"I waited," said Joan. "What I had to tell wasn't yet helpful. I thought that another night the mask might slip lower still. Besides, I--it is difficult to describe just what I felt. I felt it important just to keep that photograph in my mind, not to think about it, not to talk about it, not even to look at it too often lest I should begin to imagine the rest of the face and find something familiar in the man's carriage and shape when there was nothing really familiar to me at all. Do you understand that?" she asked, with her eyes fixed in appeal on Hanaud's face.

"Yes," replied Hanaud. "I follow your thought."

"I thought there was a chance now--the strangest chance--that the truth might be reached. I did not wish to spoil it," and she turned eagerly to Ricardo, as if, having persuaded Hanaud, she would now turn her batteries on his companion. "My whole point of view was changed. I was no longer afraid of falling asleep lest I should dream. I wished to dream, but----"

"But you could not," suggested Hanaud.

"No, that is the truth," replied Joan Carew. "Whereas before I was anxious to keep awake and yet must sleep from sheer fatigue, now that I tried consciously to put myself to sleep I remained awake all through the night, and only towards morning, when the light was coming through the blinds, dropped off into a heavy, dreamless slumber."

Hanaud nodded.

"It is a very perverse world, Miss Carew, and things go by contraries."

Ricardo listened for some note of irony in Hanaud's voice, some look of disbelief in his face. But there was neither the one nor the other. Hanaud was listening patiently.

"Then came my rehearsals," Joan Carew continued, "and that wonderful opera drove everything else out of my head. I had such a chance, if only I could make use of it! When I went to bed now, I went with that haunting music in my ears--the call of Paris--oh, you must remember it. But can you realise what it must mean to a girl who is going to sing it for the first time in Covent Garden?"
