Zarka smiled indulgently. “You are a young man, Herr Lieutenant, and your natural chivalry makes you incredulous. But if you lived a thousand years in the world you would still have much to learn of women’s ways.”

“Possibly,” Von Tressen returned; “but in this instance I am concerned only with one woman. And I say you have no right without proof to associate Fräulein Harlberg with this escapade.”

Zarka’s face began to darken. “The Fräulein has a zealous champion,” he sneered. “Perhaps, if it were worth while, I might challenge our Lieutenant’s right to that office.”

“You may,” Von Tressen cried; “and I——”

Zarka waved his arm. “For the moment we talk of proof,” he interrupted haughtily. “For that I must refer you to the lady herself.”

Galabin interposed. “This is waste of time. Von Tressen, is it worth while——?”

Zarka stopped him. “One moment, gentlemen. My suggestion is not quite so useless as you imagine. The Lieutenant has asked for proof. I will tell him where to get it. If I am wrong then I will accept the consequences.”

“Where am I to find this proof?” Von Tressen demanded.

Zarka was very calm now. “Where I told you,” he answered. “From Fräulein Harlberg herself.”

“I shall not insult her by suggesting such a thing,” Von Tressen returned indignantly.
