She decided to keep her temper.

"I might be clever enough to read minds," she said mildly, "and still be dense about divining shoulders; I confess I miss the point that you're trying to make with yours."

He was silent.

She glanced sideways at him and was thoroughly startled at the black humor displayed in his countenance.

"What is really the matter?" she asked, anxiously.

"Nothing."

She gave him another quick look, and saw that he saw her look and avoided it. Then she was angry at such poor taste displayed in the first hour of a new acquaintance, and almost thought of turning from him and insisting on being left to return to the Schweizerhof alone. But something kept her impulse in check.

"He is a genius," she thought, "and they are entirely different from other men," so she waited a moment and then spoke with the utmost earnestness.

"Please tell me what it all means, monsieur; why are you like this?"

"Because,"--he cried with a sudden pa.s.sionate outburst of feeling,--"because you have lied to me!"

"Monsieur!" she exclaimed, in a shocked voice.

"You have done that," he cried; "you have lift your eyes to heaven and swear that you were not interested in him, and then--" he stopped, and put his hands to either side of his collar as if it strangled him.

She grew pale at the sight of his emotion.

"Is it that man still?" she asked.

"But naturally it is that man still! _Je ne me fache jamais sans raison._"

"But what is there new to worry about him?"

She dared not contemplate smiling, instead she felt that the Englishman was rapidly becoming the centre of a prospective tragedy.

Von Ibn scowled until his black brows formed a terrible V just over his eyes.

"You do expect to see him in Zurich," he declared.

"But I told you that I didn't."

He laughed harshly.

"I know; but you betrayed yourself so nicely."

"How?"

"Just now, when I say where do you go from Constance, you quite forget your part, and you say, 'I do not know where _we_ shall go next.' Yes, that is what you say, 'We--_we_!'"

"And if I did."

"But of a surety you did; and I must laugh in my interior when I hear your words."

"Oh," she exclaimed quickly, "you must not say that you laughed in your interior, it isn't good English."

"Where must I laugh within myself?"

"We say, 'I laughed _to_ myself.'"

He gave another shrug, as if her correction was too petty a matter to rightfully command attention at that crisis.

"This all does seem so foolish," she said, "the idea of again having an explanation."

"I do not care for you to explain," he interrupted.

"Don't you want to know what I meant?"

"I know quite well what you meant."

"I meant my maid, she always travels with me."

He looked his thorough disbelief.

"Very pretty!" he commented.

She glanced at him and wondered why she was not disgusted, but instead her heart swelled with a pity for the unhappiness that overlaid the doubt in his face.

"Just think," she said softly, "our friendship is so very young, and you are already so very angry."

"I am not angry; what I feel is justified."

"Because I call my maid and myself 'we'!"

He stopped short, and held out his hand.

"Will you say that it is only the maid?"

Then she felt sure that she should be obliged to scream outright, even while she was summoning all her self-control to the rescue.

They were come to an angle where two streets met steeply and started thence on a joint pitch into the centre of the town. She ran her eyes quickly up and down each vista of cobblestones, and, seeing no one that she knew either near or far, put her hand into his.

"Upon my word and honor," she declared, with all the gravity which the occasion seemed to demand, "I swear that when I leave Constance my maid will be my only--"

"_a.s.sez, a.s.sez!_" he interrupted, hastily dropping her hand, "it is not need that you swear that. I can see your truth, and I have just think that it may very well come about that I shall chance to be in Constance and wish to take the train as you. It would then be most misfortunate if you have swear alone with your maid. It is better that you swear nothing."

This kaleidoscopic turn to the conversation quite took Rosina's breath away, and she remained mute.

"What hotel in Constance do you stop at?" he asked presently.

"The Insel House, of course."
