"He's one of a few that drew a lucky number, I'm thinking, sir," remarked the man who stood next to him. "Fair slave-driven, that's what we were. But that's all over now, thank God."

The rest of the passengers passed muster. They were Danish subjects—merchants and farmers, brought over at the instance of the British Government to assist in certain transactions between Great Britain and Denmark.

"A clean bill of health," reported Billy as the destroyer's sub rejoined him.

"And all serene down below," rejoined the latter. "We'll shove off. Thanks, captain, for your assistance; sorry we had to hold you up, but we're at war, you know."

"Yes," added the Dane, "and you have our moral support. I wish that we were a bigger nation. We, too, have old scores to wipe off—my family lived at Flensburg for years until '66. Flensburg is in Germany now, but some day—who knows?"

"A good sort," announced the sub, as the boat made her way back to the "Antipas." "These Danes remember Schleswig-Holstein almost if not quite as much as the French do Alsace Lorraine. I shouldn't be surprised if they chip in just before the end, if only to get their lost provinces back. How about Denmark extending frontiers to the Kiel Canal, and making that artificial waterway an international concern, eh?"

The sight of the destroyer dipping her ensign caused both officers to turn their heads and look at the "Trone." The latter was again under way and had just rehoisted her ensign after saluting the British warship.

"I feel downright sorry for those ten Britishers," thought Billy. "Their experiences have put years on to their lives."

But, had he known, he might have made an exception; for, holding aloof from his companions, Mr. William McDonald was thanking his lucky stars that he had again bluffed the inspecting officer. Within the next twelve hours William hoped to reassume the name of Andrew Norton, trusting to his natural cunning to explain satisfactorily the reason why he left the neighbourhood of Barborough so suddenly on the night of the raid.

Evidently Siegfried von Eitelwurmer, alias Andrew Norton, otherwise McDonald, had strong reasons for leaving his Fatherland in order to risk his life in the British Isles.
