I looked at the picture of her home, the great grim castle towering aloft on the river bank. A few centuries ago the Turks had fallen back beaten from before these giant walls. Then I glanced round Mrs Thistleton’s gentle trim old garden.

“I think you’ve answered my question,” I said.

She closed the book, with a shrug of her thin little shoulders, and sat silent for a moment. The oval of her face was certainly beautiful, and the thick masses of her hair were dark as night, or the inside of a dungeon in her castle of Friedenburg. (I liked to think of her having dungeons, though I really don’t know whether she had.)

“And is it for ever?” I asked.

She leant over towards me and whispered: “They know where I am.” An intense excitement seemed to be fighting against the calm she imposed on herself; but it lasted only a moment. The next instant she fell back in her chair with a sigh of dejection; a listless despair spread over her face; the satirical gleam illuminated no more the depths of her eyes. The veil had fallen over the Princess again. Only Fräulein sat beside me.

Then I made a fool of myself.

“Are there no men in Boravia?” I asked in a low voice.

This at Southam Parva, in the twentieth century, and to the governess! Moreover, from me, who have always been an advanced Liberal in politics, and hold that the Boravians are at entire liberty to change the line of succession, or to set up a republic if they be so disposed! None the less, in the Thistletons’ garden that afternoon, I did ask Fräulein whether there were men in Boravia.

She answered the question in the words she had used before.

“They know where I am,” she said, but now languidly, with half-closed eyes.
