He one day got up, and without a word of thanks or farewell to doctors, staff, or to the Crown Princess herself, he went out, and from that moment all trace had been lost of him.

Her Highness, when she heard of this, was amazed. It seemed to her as though for some unexplained reason he had no wish to receive her thanks; or else he was intent on concealing his real identity with some mysterious motive or other.

She had given orders for inquiry to be made as to who the gallant Englishman was; but although the secret agents of the Government had made inquiry in London, their efforts had been futile.

It happened over two years ago. The accident had slipped from her memory, though more than once she had wondered who might be the man who had risked his life to save hers, and had then escaped from Treysa rather than be presented to her.

And now at the moment when she was in sore need of a friend he had suddenly recognised her, and come forward to reveal himself!

Naturally she had not recognised in the dark, rather handsome face of the well-dressed Englishman the white, bloodless countenance of the insensible man with a brass-tipped cart-shaft through his chest. And he wanted to speak to her in secret? What had he, a perfect stranger, to tell her?

The small writing-room at the top of the stairs was fortunately empty, and a moment later he followed her into it, and closed the door.

Little Ignatia looked with big, wondering eyes at the stranger. The Princess seated herself in a chair, and invited the Englishman to take one.

“Princess,” he said in a refined voice, “I desire most humbly to apologise for making myself known to you, but it is unfortunately necessary.”

“Unfortunately?” she echoed. “Why unfortunately, Mr Bourne, when you risked your life for mine? At that moment you only saw a woman in grave peril; you were not aware of my station.”
