“I recall having passed you,” replied the Frenchman readily.

“That was Mr. Pembroke with whom we were talking.”

“Was it?” inquired the Frenchman politely, as he raised his eyebrows. “Then perhaps I was in error. I felt that I had seen the man before, but at that time his name was Rogers.”

“May I inquire, sir, if you know this man Rogers?”

Commander Bertrand shrugged his shoulders slightly as he asked:

“Is he a friend of yours, Monsieur Darrin?”

“No; but he had presented himself to Mr. Dalzell and me, and then had offered to do us a service.”

“I do not believe that I would trust him,” replied the Frenchman. “I cannot say, positively, that Monsieur Rogers and Monsieur Pembroke are one and the same man, but this I can assure you—that Monsieur Rogers is far from being an honest man.”

Further than that the French officer seemed disinclined to discuss the subject. After a brief chat on other topics Dave thanked the French Commander courteously and moved away. In less than two minutes, however, Dave found a chance to impart this information briefly to Danny Grin.

“Pembroke looks like a good one to dodge,” declared Ensign Dalzell.
