“‘Why?’ I murmured.

“‘Because then I shall be the ugliest woman in Copenhagen,’ she answered gaily.

“Something in that remark sent a thrill down my backbone—­there seemed an infinite pathos and lovableness in her courageous recognition of facts.  It dispensed me from the painful necessity of pretending to be unaware of her ugliness—­nay, gave it almost a cachet—­made it as possible a topic of light conversation as beauty itself.  I pressed her more fervently to come, and at last she consented, stipulating only that I should call for her rather late, after she had quite finished her household duties and the other boarders had gone off to the ball.

“Well, I took her to the ball (it was as brilliant and gay as this without being riotous), and—­will you believe it?—­she made quite a little sensation.  With a black domino covering her impossible face, and a simple evening dress, she looked as distinguee as my best girl would have done.  Her skin was good, and her figure, freed from the distracting companionship of her face, was rather elegant, while the lively humour of her conversation had now fair play.  She danced well, too, with a natural grace.  I believe she enjoyed her incog. almost as much as the ball, and I began to feel quite like a fairy godmother who was giving poor little Cinderella an outing, and to regret that I had not the power to make her beautiful for ever, or at least to make life one eternal fancy ball, at which silk masks might veil the horrors of reality.  I dare say, too, she got a certain kudos through dancing so much with me, for, as I have told you ad nauseam, this lovely costume of mine was the hit of the evening, and the Kronprinds asked for the honour of an introduction to me.  It was rather funny—­the circuitous etiquette.  I had to be first introduced to his aide-de-camp.  This was done through an actress of the Kongelige Theatre, with whom I had been polking (he knew all the soubrettes, that aide-de-camp!).  Then he introduced me to the Kronprinds, and I held out my hand and shook his royal paw heartily.  He was very gracious to me, learning I was an American, and complimented me on my dress and my dancing, and I answered him affably; and the natives, gathered round at a respectful distance, eyed me with reverent curiosity.  But at last, when the music struck up again, I said, ‘Excuse me, I am engaged for this waltz!’ and hurried off to dance with my Cinderella, much to the amazement of the Danes, who wondered audibly what mighty foreign potentate His Royal Highness had been making himself agreeable to.”

“It was plain enough,” I broke in.  “His Satanic Majesty, of course.”

“I am glad you interrupted me,” he said, “for you give me an opening to state that the Kronprinds has nothing to do with the story.  You, of course, would have left him out; but I am only an amateur, and I get my threads mixed.”

“Shut up!” I cried.  “I mean—­go on.”
