Stepping from the glare of those gleaming parlor lights into the gloom of that narrow passage, blinded me for the instant, yet a moment later, I became aware of the distant glimmer of a candle, the faint reflection revealing the girl's face.

"Please do not talk; do not ask anything—yet," she urged hurriedly, noiselessly closing the door at my back, and as instantly gripping my sleeve. Her breath came quickly; her voice trembled from suppressed excitement. "Come with me, beyond the light yonder."

I followed her guidance, bewildered, yet having every confidence the reason for this mysterious occurrence must be fully justified. The passage curved slightly, terminating at a closed door. Scarce a reflection of the candle reached us here, yet my eyes were by now sufficiently accustomed to the gloom so that I could trace the outlines of her face. A vague doubt took possession of me.

"You are causing me to run away from Grant," I protested blindly. "You are making me appear afraid to meet him."

"No, it is not that," swiftly. "He was not coming to you personally at all—you were to be arrested."

"What! He knew me then?"

"I am not sure—some one did, and mentioned his suspicions. Captain Grant was glad enough of an excuse, no doubt, but he," the soft voice faltering, "he made a mistake in twitting me for being friendly toward you."

"And you came to warn, to save me!" I exclaimed, pressing her hand.

"That was nothing; I could do no less. I am only glad I knew the way."

"You mean how you might reach me first?"

"Yes; it came to me in a flash when he first left me alone, only I was not certain in which parlor you would be waiting. I ran through the kitchen and down the back stairs; I helped the officers plan their decorations, and in that way learned of this private passage beneath the stairs. It was easy, but—oh, listen! they are in there now!"

We could hear voices through the intervening wall clearly enough to even distinguish words, as the speakers exercised little restraint. I felt the girl's slender figure press against me in the narrow space where we stood, and I clung to her hand, both remaining motionless and silent.

"The fellow has run, Grant," boomed some one hoarsely, "either afraid, or else what you say he is. See here, boy, did you see any one in here lately in scarlet jacket?"

"I don' just 'member, sah," answered a negro, hesitatingly. "I was busy over dar' cleanin' de side-boa'd."

"Well, he's not here now, that's certain," broke in Grant impatiently, "and we've been in all the parlors? What next, MacHugh?"

"Try to head him off before he can get out of the city, of course. That's his game, probably. Osborne, have Carter come here at once. Why didn't you nab the fellow upstairs, Captain? Fool play that, sending him down here."

"I didn't wish to create a row in the ball-room; he was with Claire Mortimer—"

"Oh, I see," laughing coarsely. "Something besides military duty involved, eh?"

"I'll trouble you to be a trifle more careful, MacHugh," Grant said stiffly. "The fellow did her a small service in the afternoon, and she couldn't refuse dancing with him, as he was in uniform, and apparently all right. I advise you to drop that part of the affair. Here's Carter now."

I could hear the click of the newcomer's spurs as he crossed the room. MacHugh chuckled.

"Touchy about it just the same, I see; however we'll pass up the lady. Carter, there has been a spy in here to-night, calling himself Lieutenant Fortesque, of the 42nd Regiment. He came through the lines this morning with despatches for Howe, I understand. Did you meet him?"

"No, sir, but one of my men was riding about with him all day—Watts; I heard him telling about it an hour ago."

"Is that so? Where'd they go?"

"Covered everything, I judge, from Callowhill to the Lower Battery. Watts said he asked questions of everybody they met, but he didn't take any notes. He liked the fellow, but thought he was mighty inquisitive. Where is he now, sir?"

"The devil knows, I don't, and you'll have to find out. He'll head northwest likely; he'll never try to cross the river here. How many men have you?"

"Twenty."

"Scatter them to every north post. The fellow had no horse, and your troopers can easily get ahead of him. Hurry up now." Carter departed with click of steel, and MacHugh evidently turned to his companion.

"We'll catch the lad all right, Grant. Some of those outposts will nab him before daylight. No use our waiting around here; let's go back upstairs."

The girl's nervous grasp on my arm tightened, her lips pressed close to my ear.

"I—I must get back to my place at the table," she whispered. "Surely you know what to do; this is a rear door; there are stables a hundred feet away; you must get a horse, and ride fast—you—you will do this!"

"Yes, of course—but how can I thank you?"

"Don't try; don't ever even think of it again. I hardly know what mad impulse sent me here. Now I have but one thought—to hurry you away, and get safely back myself—you will go?"

"Yes—but—"

"Not now! there is no time for explanation, promises, anything. You heard what they said; every avenue of escape will be blocked within an hour. If you go at once you can outride them—please, please go!"

She held out her hand, and I grasped it warmly, unable longer to war against the pitiful appeal in her voice.

"Yes, I'll go, at once. But I take away with me a memory which will never permit me to be satisfied until we meet again. We have been together so short a time—"

"Had it been longer," she interrupted, "you would know me better, and care less, perhaps. I am a sham; a cheat," a trifle of bitterness in the tone. "You will learn all that some day, and laugh at yourself. Oh, I know you will; so not another word, sir. I am going; then, perhaps, you will."

There was a slight pressure of her fingers, and she had vanished so quickly I could only stare blindly along the deserted passage. Yet, an instant later, the peril of my predicament flashed back upon my mind, and I faced the immediate necessity for action. What her strange words might mean could not be interpreted; I made no attempt to comprehend. Now I must find means of escape, and learn the truth later. I opened the door cautiously, and stepped without, every nerve taut, every muscle braced for action. It was a star-lit night, and the numerous rear windows of the mansion cast a glare of light for some distance. The dark shadow of a high fence alone promised concealment, and, holding my sword tightly, I crept in that direction, breathing again more freely as I reached its protection unobserved. There was a guard stationed before the stable door—a Grenadier, from the outline of his hat—and others, a little group, were sitting on the grass a dozen feet away. If they had not been already warned I might gain a horse by boldness, but the probability was that here was where Carter had mounted his squad, and I would merely walk forward into a trap. I had better chance the possibility that some visitor had left a horse tied in front, or to one of the stands. With this possibility in mind I turned, and skirted the house, making myself as inconspicuous as possible. There were soldiers on the outside steps; I heard their voices without seeing them, and was thus driven to run swiftly across an open space, memory guiding me toward the opposite pavilion. Breathless, with heart beating fast, I crouched low in the shadow, endeavoring to make out my more immediate surroundings. There were no horses there, but I could clearly distinguish the stomping of restless hoofs somewhere to the right. As I straightened up, determined upon discovering an empty saddle if possible, the figure of a man suddenly loomed directly in front, advancing toward me. In startled surprise I took one step backward, but was too late. Already the eyes of the newcomer had perceived my presence, and he sprang forward, tugging at his sword.

"Hold on there! hold on!" he commanded shortly. "Who are you? What the devil are you skulking about out here for?"

It was Grant beyond a doubt; I would recognize the peculiar snarl of that voice in a thousand. He had not gone upstairs then; had not rejoined the lady in the dining-room. What would she think of his absence? What would she do when she realized its probable meaning? Someway I was not frightened, at thus meeting him, but glad—if those others would only keep away, and let us settle the affair between us. Here was his test—a coward would cry out an alarm, summon the guard to his assistance, but, if the fellow's nerve only held, or if he hated me badly enough, he'd fight it out alone. All this came to me in a flash, and the words of challenge spoken before he even grasped the thought of who I was.

"So I have discovered you, have I? Why did you fail to keep our appointment within?"

He drew up sharply, with an oath, peering at me through the dark, bewildered by my speech.

"The spy! Ye gods, what luck! Do you mean to insinuate I ran away, sir?"

"How else could I interpret it?" I questioned coolly, determined to taunt him to action. "I waited where you told me till I was tired. Perhaps you will oblige me by explaining your purpose."

He muttered something, but without comprehending its purport I went on threateningly:

"And I think you made use of the word spy just now. Did you mistake me for another?"

"Mistake you? No; I'd know you in hell," he burst forth, anger making his voice tremble. "I called you a spy, and you are one, you sneaking night rat. You never waited for me in the parlor; if you had you'd now be under arrest."

"Oh, so that was the plan?"

"Yes, that was it, Mister Lieutenant Fortesque."

"Well, Grant," I said sternly, "I've got just one answer to make you. You can call your guard, or you can fight it out with me here. Whichever you choose will depend upon whether you are a man, or a cur." I took a step nearer, watching him as best I could in the dark. "You are an unmitigated liar, sir," and with sudden sweep of the arm I struck him with open hand. "Probably you will realize what that means."

For an instant he remained so still I doubted him, even held him cheap; then the breath surged through his clinched teeth in a mad oath. He surged toward me, but my sword was out, the steel blocking his advance.

"You—you actually mean fight?"

"Why not? Isn't that cause enough? If not I will furnish more."

"I do not fight spies—"

"Stop! That silly charge is merely an excuse. You do not believe it yourself. You wanted a quarrel yonder in the ball-room. The expression of your eyes was an insult. Don't evade now. I am here, wearing the uniform of the British army. I have every right of a gentleman, and you will cross swords, or I'll brand you coward wherever there is an English garrison."

The fellow was certainly not afraid, yet he hesitated, not quite clear in his own mind what he had better do. I might be a spy, and I might not; he possessed no doubt a moment before, yet the very boldness of my words had already half convinced him there might be some mistake. Should he call to the men on the steps yonder, denounce me, and turn me over to the guard? That was the easiest way for him, the greater disgrace to me. Yet if, by any chance, I proved later innocent of the charge, then he would become the laughingstock of the army. I heard his teeth grate savagely as he realized his dilemma, and laughed outright.

"You do not seem altogether pleased, my friend; what are you, a toy soldier?"

"Hell's acre! I'll show you what I am."

I saw the sudden flash of his drawn blade, and flung up my own in guard.

"Wait; not here, Captain," I insisted quickly. "We're far too near your watchful friends yonder; besides the light is poor. Let's try our fortunes beyond the pavilion, where it can be simply man to man."

He turned without a word, and I followed, eager enough to have done with the business. The stars gleamed on the naked weapons held in our hands, but we exchanged no words until we had rounded the corner, and come forth into the open space beyond.
