The old doctor looked pained at the question. "But you forget," he said, "that it is the power of your secret and not my confession that has restored Marguerite. The confession is only a matter of form, to satisfy the wagging tongues of Royal Society." "Do you mean," I asked, "that she will not be well received there because she was born out of wedlock?" "Not at all," replied Zimmern; "it was the failure to confess the father, not the fact of her unwedded motherhood, that brought the punishment. There are many love-children born on the Royal Level and they suffer only a failure of inheritance of wealth from the father. But if they be girls of charm and beauty, and if, as Marguerite now stands credited, they be of rich Royal blood, they are very popular and much sought after. But without the record of the father they cannot be admitted into Royal Society, for the record of the blood lines would be lost, and that, you see, is essential. Social precedent, the value in the matrimonial market, all rest upon it. Marguerite is indeed fortunate; with His Majesty's signature attesting my confession, she has nothing more to fear. But I daresay they shall try their best to win her from you for some shallow-minded prince." "But when," I asked, "is she to go? His Majesty seemed very gracious, but do you realize that I still possess my secret of the protium formulas?" "And do you still hesitate to give them up?" asked Marguerite. "For your freedom, dear, I shall reveal them gladly." "But," cried Marguerite, "you must not give them up just for me,--if there is any way you can use them for our great plan." "Nothing," spoke up Zimmern, "could be gained now by further secrecy but trouble for us all; and by acceding, both you and Marguerite win your places on the Royal Level, where you can better serve our cause. That is, if you are still with us. It may be harder for you, now that you have won the richest privileges that Germany has to offer, to remember those who struggle in the darkness." "But I shall remember," I said, giving him my hand. "I believe you will," said Zimmern feelingly, "and I know I can count on Marguerite. You will both have opportunities to see much of the officers of the Submarine Service. The German race may yet be freed from this sunless prison, if you can find one among them who can be won to our cause." ~2~ I reported the next morning to the Chemical Staff, by whom I was treated with deferential respect. I was immediately installed in my new office, as Director of the Protium Works. While I set about supervising the manufacture of apparatus for the new process, other members of the staff, now furnished with the correct formulas repeated the demonstration without my assistance.
