"Very well. And you will return it to me?"

"I promise."

And so it was agreed that Stephen should take the letter with him, which he promised to return together with the earliest news of the result of his court-martial.

He stood up.

Stephen came out the little white gate closing it very deliberately behind him and immediately set off at a brisk pace down the street.

Every fiber within him thrilled with energy. The road was dusty and hot, and his pace grew very strenuous and fervent. There was no breeze; there was no sound of wheels; all was quiet as the bells tolled out the hour of six. Nevertheless he trudged along with great haste without once stopping until he had reached the door of his lodgings.

He turned the key and entered, closing the door behind him and taking the greatest of care to see that it was properly bolted. Flinging his hat into a chair as he pa.s.sed, he went immediately to the table which served as his desk. While he pulled himself close to it, he reached into his pocket for the letter. He opened it before him and read it. Then he sat back and read it again; this time aloud:

Co. 13

Headquarters, New York.

15 July, 1778.

Madame:--I am happy to have this opportunity to once again express my humble respects to you and to a.s.sure you that yourself together with your generous and hospitable friends are causing us much concern separated as we are by the duress of a merciless war. We lead a monotonous life, for outside of the regularities of army life, there is little to entertain us. Our hearts are torn with pangs of regret as we recall the golden days of the Mischienza.

I would I could be of some service to you here, that you may understand that my protestations of zeal made on former occasions were not without some degree of sincerity. Let me add, too, that your many friends here present unite with me in these same sentiments of unaffected and genuine devotion.

I beg you to present my best respects to your sisters, to the Misses Chew, and to Mrs. Shippen and Mrs. Chew.

I have the honor to be with the greatest regard, Madame, your most obedient and most humble servant.

W. CATHCART.

Miss Peggy Shippen, Philadelphia.

His face was working oddly, as if with mingled perplexity and pleasure; and he caught his lip in his teeth, as his manner was. What was this innocent note? Could it be so simple as it appeared? Vague possibilities pa.s.sed through his mind.

The longer he gazed at it the more simple it became, so that he was on the point of folding it and replacing it in his pocket, sadly disconcerted at its insignificance. He had hoped that he might have stumbled across something of real value, not only some secret information concerning the designs of the enemy, but also some evidence of an incriminating nature against his own acquaintances in the city.

Suddenly he thought he saw certain letters dotted over, not entirely perceptible, yet quite discernible. He turned the paper over. The reverse was perfectly clear. He held it to the light but nothing appeared through.

"By Jove!" he exclaimed softly.

He looked closely again. Sure enough there were faint markings on several of the letters. The "H" was marked. So with the "V" in "have,"

and the "A" and the "L." s.n.a.t.c.hing a pencil and a sheet of paper he made a list of the letters so marked.

HVANLADERIIGAERODIRCUTN

This meant nothing. That was apparent; nor could he make sense out of any combination of letters. He knew that there were certain codes whereby the two progressions, arithmetical and geometric were employed in their composition, but this seemingly answered to none of them. He went over the list again, comparing them with the marked letters as found in the note. Yes, they were identical. He had copied them faithfully.

He sighed and ran his fingers through his hair.

"So this was sent to Peggy from New York," he muttered to himself. "I strongly suspected that she was in communication with her British friends, although I never came in contact with the slightest evidence.

This certainly proves it."

He held the letter at a distance from him, attentively surveying it.

"And General Arnold has been interested, too. Very likely, Marjorie's hypothesis is the true one. They had been reading the note when the newcomers arrived on the scene and the General stuck it in his belt until their greetings had been ended. Neither of them now know of its whereabouts; that much is certain."

He stood up suddenly and strode about the room, his hands clasped behind him. Going to the window, he peered out through the small panes of gla.s.s of the uncurtained upper half. There burned the light across the dusk--a patch of jeweled color in the far off western sky. Yet it awakened no emotion at all.

His mind was engaged in the most intricate process of thought. He deduced a hundred conclusions and rejected them with equal prompt.i.tude.

He greatly admired General Arnold as the bravest leader in the line, whose courage, whose heroism, whose fearlessness had brought him signal successes. There was no more popular soldier in the army, nor one more capable of more effective service. To have his career clogged or goaded by a woman, who when she either loves or hates will dare anything, would be a dreadful calamity. Yet it seemed as if he had surrendered his better self.

This man Anderson puzzled him. Personally he was disposed to dislike him, that being the logical effect of his relations with him. At the Coffee House, where he had met him, and where he had suffered his better judgment to become dormant, it was this man who had brought him to the pitch of irritation by means of a religious argument, while at the trial it was the same Anderson who appeared as an excellent witness and who by his clever, deliberate and self-possessed manner, made a strong point for the Colonel in the minds of the court.

What was his origin? That he might never know, for of all subjects, this was the most artfully avoided. In the capacity of a civilian he was engaged in no fixed occupation so far as could be learned, and it was commonly known that he was a frequent visitor at the Governor's mansion.

That he did not belong to the service, he knew very well, unless the man was affecting a disguise; this, however, he thought highly improbable.

The French Alliance had been further confirmed by the arrival of the fleet, which brought many strangers to the city. Now as he thought of it, he had a certain manner about him somewhat characteristic of the French people, and it was entirely possible that he might have disembarked with the French visitors. He was a mystery anyhow.

"Strange I should stumble across this chap," he mumbled to himself.

He awoke with a start.

Just what the hour was, he could not know, for it was intensely dark. He reckoned that it could not be long after midnight, for it seemed as if he had scarcely fallen asleep. But there was a wonderful burst of light to his mind, a complete clarity of thought into which often those do awake who have fallen asleep in a state of great mental conflict. He opened his eyes and, as it were, beheld all that he was about to do; there was also a very vivid memory of his experience of the evening.

He arose hurriedly and struck a light. He seized the letter in search of the momentous something that had dawned upon him with wonderful intensity.

"Company Thirteen," he remarked with deliberate emphasis. "That must be the key."

And seizing a paper he wrote the order of letters which he had copied from the note a few hours before.

HVANLADERIIG

He stopped at the thirteenth, and began a second line immediately under the line he had just written.

AERODIRCUTN

It inserted perfectly when read up and down beginning with the letter "H". He completed the sentence.
