"I have made no mistake, Karl," he answered.

"I am not so sure," I replied. "The girl you placed in my arms seemed
taller by half a head than Yolanda. I noticed her while she was
standing. She seemed rounder and much heavier in form; but I, too,
thought she was Yolanda, and, after all, you may be right."

"I caught but a glimpse of her face, and that poorly," said Max. "It is
difficult to see anything looking downward out of a helmet; one must
look straight ahead. But the glimpse I had of her face satisfied me."

"Do not be too sure, Max. I once took another man for myself." Max
laughed. "I am sure no one could have told us apart. He was the Pope,
and I his cousin. Yolanda herself once told me--I believe she has also
told you--that she has the honor to resemble the princess."

I did not wish to lie to Max, and you will note that I did not say the
princess was not Yolanda. Still, I wished him to remain ignorant upon
the important question until Yolanda should see fit to enlighten him. I
was not sure of her motive in maintaining the alias, though I was
certain it was more than a mere whim. How great it was I could not know.
Should she persist in it I would help her up to the point of telling Max
a downright falsehood. There I would stop.

We spent two evenings at Castleman's, but did not see Yolanda. On the
first evening, after an hour of listlessness, Max hesitatingly asked:--

"Where is Yo--that is, the princess has not been here this evening."
