"Yes, Captain Cathcart. But it contained more. There was a cipher message."

"In cipher?" Then after a moment. "Did she know of it?"

"I am inclined to think that she did. Otherwise it would not have been directed to her."

This was news indeed. No longer did she recline against the seat of the canoe, but raised herself upright.

"How did you ever discover it?"

"My first reading of the note filled me with suspicion. Its tone was too impersonal. When I asked for it, I was impelled by the sole desire to study it the more carefully at my own leisure. That night I found certain markings over some of the letters. These I jotted down and rearranged until I had found the hidden message."

She gazed at him in wonder.

"It was directed to her, I presume, because of her friendship with the Military Governor; and carried the suggestion that His Excellency be interested in the proposed formation of the Regiment. From that moment my energies were directed to one sole end. I watched Arnold and those whom he was wont to entertain. Eventually the trail narrowed down to Peggy and Anderson."

She drew a deep breath, but said nothing.
