"You suspected him before our conversation. You, yourself, heard it from his own lips in the garden."

"Yes, I did. But the note!"

"What note?"

"The note you gave me to read."

"Peggy's letter which I found at her house?"

"The same. Have I never told you?"

"Never!" was the slow response. "You know you returned it to me without comment."

He was puzzled. For he wondered how he had failed to acquaint her with so important an item.

"When you allowed me to take that letter you furnished me with my first clew."

She aroused herself and looked seriously at him.

"I?... Why.... I never read it. What did it contain? I had supposed it to be a personal letter."

"And so it was,--apparently. It proved to be a letter from one of Peggy's New York friends."

"A Mischienza friend, undoubtedly."

"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.

"The night I played the spy in the park my theory was confirmed."

"Yes, you told me of that incident. It was not far from here."

She turned to search the distance behind her.

"No. Just down the sh.o.r.e behind his great house." He pointed with his finger in the direction of Mount Pleasant.

"And Peggy was a party to the conspiracy!" she exclaimed with an audible sigh.

"She exercised her influence over Arnold from the start. She and Anderson were in perfect accord."

"I am sorry. She has disappointed me greatly."

"She has a very pretty manner and a most winsome expression; but she is extremely subtle and fully accomplished in all manner of artifice. She was far too clever for your frank simplicity."

"I never suspected her for an instant."

"It was she who set the trap for Arnold; it was she who made it possible for Anderson to rise to the heights of favor and influence; it was she who encouraged her husband in his misuse of authority; and I venture to say, it was she who rendered effective the degree of friendship which began to exist between yourself and this gentleman."

Marjorie blushed at the irony.

They were drifting above the cove in the slowest manner. Only occasionally did he dip the paddle into the water to change the course of the little craft, or to push it ahead a little into the more shaded places. Marjorie did not a.s.sist in this, for he desired her to sit in the bow facing him, while he, himself, essayed the task of paddler.

There was little of exertion, however, for the two had no other object in view than the company of their own selves. And so they drifted aimlessly about the stream.

"Yes, I think that I ought to leave tomorrow for White Plains to confer with His Excellency."

"I should be the last to hinder you in the performance of duty. By all means, go."

"Of course it may be no more than a suspicion, but if you are sure of what Anderson said, then I think that the matter should be brought to the attention of the Commander-in-chief."

"Of course, you understand that Mr. Anderson told me nothing definite.

But he did hint that General Arnold should be placed in command of a more responsible post in the American army; and that steps should be taken to have him promoted to the Second in Command."

Stephen thought for a minute.

"That sounds innocent enough. But you must remember that events have come to light in the past fortnight which for months had lain concealed in the minds of these two men. Who knows but what this was included in their nefarious scheme. I am uneasy about it all, and must see the chief."

"But you will come back?"

"At once unless prevented by a detail to a new field. I am subject at all times to the will of my leader."

Her face fell.

II

The solemn stillness, the almost noiseless motion of the boat, the livid shades surrounding the place, all contributed to the mood of pensiveness and meditation which was rapidly stealing upon them. The very silence of the cove was infectious. Marjorie felt it almost immediately, and relaxed without a murmur.

A stream of thoughts began to course in continuous procession through her mind, awakening there whatever latent images lay buried in her memory, and fashioning new ideas and seemingly possible situations from her experiences of the past year. Now she suddenly discovered her former interest quickened to a violent degree. She was living over again the memories of the happy hours of other days.

Certainly Stephen was as constant as ever. To her discerning eye his manner of action conveyed no other impression. But he was the same enigma, however, as far as the communication of thought was concerned, and she knew no more of his pleasures and desires than she did of the inspirations of his soul.

It was the first time in months she had seen and taken delight in his own old self. Never had he been so attentive quite as John Anderson, nor so profuse in his protestations, nor so ready with his apologies. And what was more she did not expect him to be. But he was more sincere when it came to a question of unfolding one's own convictions, more engaging where will-power, propriety, performance of duty, were concerned. He alone possessed the rule to which all, in her own mind, were obliged to conform. And so she was compelled to admire him.

These fond memories suffered an interruption by a vision of the extreme disquietude produced upon Stephen by her unfortunate acquaintanceship with Mr. Anderson. And yet she had been profoundly sincere with herself.
