"I--I think I do understand," she said, in a low voice.

Yes, from the very beginning, as a small child, this passion of protection, of loyalty, had been hers. Strange legacy from an unknown father! He smiled content.

"Glad to hear it. You're not a bit like your mother--you're like me, and your brothers--half-brothers, I mean. So I had to go. It was just after the break up of Europe and Napoleon, when half the political refugees came to their own again--and he did amongst others. So I had to go." Again he paused, and for the first time Marrion felt the touch of kinship between them. He had to go; that was just it! She had had to be loyal to Duke. "You are not in the least like your mother," he said again suddenly, "you are like us." Yet again he paused. "Have you anything you can give me to drink?" he asked. "I have something to say to you, and I feel--limp."

She gave him a restorative and he brisked up. Time was passing, but she had learnt many things during the last month and knew that physical rest would be impossible until the mental rest was assured.

"Don't talk too much," she said. "I think I shall understand--what is it?"

"This box," he said. "It holds--my credentials. There is a false top--see, you press this spring--so."

As he spoke the lid appeared to part in two, disclosing a folded piece of paper.

"Don't read it now--but it will tell you everything. I was on secret service and it was of importance no one should know. It is of importance still. If I hadn't met you I should have said nothing. But now--you'll do me this good turn, I expect--for, after all, I am your father."

A cynical smile curved his lips, his blue eyes met hers in a challenge.

Almost staggered by the strangeness of what was happening, Marrion was yet aware of something deep down in her which gave instant response to this claim upon her.
