"To the porte-cochère, and knock upon the door," she said, as she vanished behind the summer-house.

Evidently the persuasive Solonika had been at work and won her expected victory, for the grim, old butler smiled graciously and bade me enter.

"Would Monsieur the physician desire to see the Prince?" he asked.

Somewhere in the castle the Princess was waiting, expecting my coming. Why not first see the Prince and then call upon her? Thus might I satisfy my great desire without arousing suspicion.

"Yes, I would see the Prince," I answered.

The old man bent his back in a half bow and smilingly led me with all the dignity and speed of a turtle to the Prince's quarters, which fortunately were but a short distance from the reception hall. If the ways of those who love the darkness are evil, the Red Fox's ways must certainly be evil, for the interior of his castle was very dark. The windows were screened with heavy curtains, permitting little daylight to enter. My eyes, fresh from the sunlight, had to become accustomed to the lack of light before I could see my way about. I hung close upon the heels of my slow guide until he paused in a doorway and announced in a stately manner:

"Monsieur le doctaire for the Prince."

There was the sound of a chair being moved back as if some one arose. I bowed upon the threshold, looking swiftly about. The Duke and the Prince were before me, but Solonika was nowhere to be seen. The Duke was standing beside a table acknowledging my bow. He was dressed in the same quaint manner as when I had seen him two days before.

His son, the Prince, remained seated on the opposite side of the table. His back was toward me, and he did not turn. He was attired in a long, full-skirted coat of black, black knee breeches with buckles at the knee, black silk stockings and silver-buckled, low black shoes. Leaning against the arm of his high-backed carved chair was his sword. It had evidently been uncomfortable, and was laid aside belt and all. The Prince's right arm was in a sling.

The two had been interested in a game of cards when I interrupted them. Judging from the formation of the pasteboards upon the green cloth, they were playing "double solitaire," that paradoxical game for one which two or three can play. It is also one of the few games of cards which can be played with one hand.
