Suddenly Ross Trefusis recognized the man. He almost felt inclined to laugh at his suspicions. It was Dr. Ramblethorne, the medical practitioner at St. Bedal—a town of considerable importance about seven miles from Killigwent Hall. The doctor was a frequent guest of Admiral Trefusis, and was generally considered a good, all-round sportsman. He was about thirty years of age, over six feet in height, of sinewy frame and of great muscular power. He was the wildest motorist in that part of Cornwall, as the endorsements on his driver's licence testified. A keen golfer, good shot, and fisherman, he was also a botanist; and that, perhaps, thought Ross, might account for his presence on St. Mena's Island, although it was difficult to reconcile the fact that Ramblethorne had an appointment with a stranger at this desolate spot. If a joint botanic expedition had been fixed up, why had not the two men met on the mainland?

The unknown made no attempt to advance to meet the doctor. Instead, he remained within the ruins until Ramblethorne entered.

Their greeting was a surprise even to the lads, for the doctor, holding out his hand, exclaimed in German:

"Well met, von Ruhle! Let us hope that your arrangements will prove satisfactory."

CHAPTER II

The Tables Turned

Both Ross Trefusis and Vernon Haye understood and could speak German. Ross was especially good in his knowledge of the language of the modern Hun, for in his early youth he had been inflicted with a German governess. Since German is one of the subjects for Sandhurst—for which both lads were preparing—their knowledge had been considerably improved under the cast-iron rule of a native professor.

"Eminently satisfactory," replied von Ruhle. "We will go into details later. You had no difficulty in coming here, I hope?"

"None whatever."
