At nine o'clock that night the Crown-Prince, gay in his Hussar uniform, burst into the room wherein I was attending to the correspondence.

"What in the name of Fate does all this mean, Heltzendorff?" he demanded. "Why did the Emperor fail to reply to my message?"

"I delivered it," I said. And then I described what took place in the Emperor's private dining-room. When I mentioned the name of Minckwitz the Crown-Prince started and his cheeks blanched.

"Did he ask you that?" he gasped.

"Yes. I told him the only person I knew of that name was Count von Minckwitz."

"Ah, that little fat, old Master of the Court. Oh! The Emperor knows him well enough. It is somebody else he is referring to."

"Do you know him?" I asked eagerly.

"Me? Why—why, of course not!" was "Willie's" quick reply, in a tone which showed me that he was not telling the truth.

"His Majesty wishes to see you at once," I urged, full of wonder.

I could plainly see that His Imperial Highness had been much upset at mention of the mysterious person called Minckwitz. What could the Emperor know of him? Was there some scandal at the root of it all, some facts which the Crown-Prince feared might be revealed?
