"Oh, you are divorced?"

"I am not."

"Then if you feel that I have offended you I should think your husband would be the proper man to appeal to," he said with the utmost coolness.

He seemed like a trainer, prodding tame animals with sharp prongs out of the lethargy of their caged lives to stir them to viciousness. Turning to Karl he went on:

"However, if you wish it, I am also at your disposal. But do you not see, madam, that it would be an admission on your part?"

He spoke as one who had dared read every secret thought of each. Bewildered, Karl cried out:

"What does all this talk mean? I don't understand anything. You come in here unannounced; I don't know how nor from where. You make us feel quite uncomfortable, just as if you had trapped us in some compromising situation."

"Yes, yes, that is it," Olga cried, relieved at Karl's outburst.

The stranger looked at them amusedly.

"You may be as impolite to me as you wish; I cannot go," he said.
