Her hand was in mine, my arm already around her waist, when the officer bowed before us. He had been but a dim figure in the afternoon, but now I saw him for a tall, slender man, somewhat swarthy of face, with black hair and moustache, and a keen eye, attired in the green and white of the Queen's Rangers. He smiled, but with a sarcastic curl to the upper lip not altogether pleasant.

"Your pardon, Mistress Claire," he said boldly, sweeping me with a supercilious glance, "but am I mistaken in believing this waltz was pledged to me?"

"By mistake, Captain," her lips smiling, her eyes steady. "It seems I had overlooked a promise made during the afternoon."

"Oh, indeed," he turned toward me, staring insolently. "The hero of the rescue, I presume."

I felt the restraining pressure of her hand upon my sleeve, and her voice replied calmly, before I succeeded in finding words.

"This is the gentleman who protected me from the mob, if that be what you mean. Permit me to present Captain Grant of the Queen's Rangers, Lieutenant—pardon my having already forgotten your name."

"Fortesque," I stammered, intensely hating the necessary deception.

"Ah, yes—Lieutenant Fortesque, of the 42nd British Foot."

We bowed coldly, neither extending a hand, the Captain twisting his moustache as he continued staring at me.

"Fortesque," he repeated slowly. "Fortesque; not of this garrison, I believe."

"No, from New York," coolly. "I regret having interfered with your programme."

"Don't mention it; there are other ladies present, and, no doubt, your gallant act was worthy the reward; a pleasant evening, sir," and he drew aside, stiffly military. Eager to lose as little as possible of the measure I swung my partner forward, catching glimpse again of the man's face as we circled.

"Pleasant disposition," I ventured, without meaning to be uncivil.

"Oh, very," and her eyes met mine frankly. "But you must not quarrel with him; that is his one specialty, you know."

"Is the warning on your account, or my own?"

"Both, perhaps. Captain Grant's family and mine are neighbors—or were before war intervened—and between our fathers exists a life-long friendship. I could never consent to be the cause of his quarrelling with any one, and I have reason to know how quick tempered he is."

"I have little use for any man who swaggers about seeking trouble," I returned, as she hesitated. "It has been my experience that there is usually cowardice back of such a disposition."

"Not in this case," earnestly. "Captain Grant's courage has been sufficiently tested already. I warn you not to presume on your theory so far as he is concerned. I advise the safer course."

"What is that?"

Her eyes met mine, smiling slightly, and yet grave enough in their depths.

"To let this one dance prove sufficient reward for your act of rescue."

"You request this?"

"Oh, you must not place the entire burden of decision on me, sir. I can only suggest."

"Has Captain Grant any authority to dictate who shall be your partner?"

Her lashes lifted, and then fell before my gaze.

"He at least assumes the power, and generally with fair success. I must ask to be excused from discussing this matter further now, but—but," her voice trembled to a whisper, "I—I am sure your safety depends upon your leaving me."

Astonished by these words, suddenly wondering if she suspected me, scarcely comprehending what she meant, I stared into her face, as we circled the room. Grant stood stiffly against the wall where we left him, his eyes fastened moodily on the crowd; I realized his presence, yet my whole thought was concentrated on the girl, the strands of her hair brushing my lips, her steps lightly following the music, her eyes downcast. Into the cheeks there came a flush of pink, and she glanced up to read the surprise in my face.

"Do I need to say more?"

"Yes, you must," I insisted, "you can never believe I would leave you because of personal fear."

"I did not know—at first. Now I realize it will require a higher motive to influence you; not love of life, but love of country."

I felt the closer clasp of her fingers on my guiding hand, and knew I took a deep breath of surprise.

"Lean your head just a little closer," she whispered. "I—I know you, Major Lawrence, and—and I wish you well."

How I kept to the measure I cannot now imagine, for, in an instant, all my house of cards crumbled into nothingness. She knew me, this blue-eyed girl; knew me, and sought to aid my mission, this daughter of a loyalist, this lady of the Blended Rose. It was inconceivable, and yet a fact—my name had been whispered by her lips.

Suddenly she looked up laughing, as though to make others feel that we conversed lightly. We passed Grant, even as I held my breath, almost afraid to venture with words. Yet they would not be restrained.

"You certainly startled me; how do you know this? Surely we have never met before?"

"I refuse to be questioned, sir; it means nothing how I know—the fact that I do should be sufficient."

"But Mistress Claire—"

"Rather Mistress Mortimer."

"Yet the Captain called you Claire."

"And we were children together—you can scarcely claim such familiarity."

"I warrant you can name me."

"Allen, is it not, sir?"

What was it the witch did not know! This was no guess-work, surely, and yet how could her strange knowledge be accounted for? Sweet as the face was, greatly as it had attracted me, there was nothing to awaken a throb of memory. Surely I could never have seen her before, and forgotten; that would have been impossible. The music ceased, leaving us at the farther extremity of the hall.

"And now you will go?" she questioned eagerly.

"Do you mean, leave here?"

"Yes; you said once to-night, that but for me you would be riding yonder. I realized all you meant, and you must not remain. The guard-lines are slack to-night, and you can get through, but if you wait until to-morrow it may be too late. Believe me, I am your friend, a friend of your cause."

"I do believe you; I could not connect you with deceit, but I am bewildered at this sudden exposure. Does Captain Grant also suspect my identity?"

"I think not—not yet, at least, for if he did you would be under arrest. But there are others here who would recognize you just as I have. There is no mystery about it. I was in Philadelphia when the Continental troops were here, and you were pointed out to me then. No, we have never met, yet I was sure I recognized you this afternoon."

"I was pointed out to you by whom?"

"My brother—my twin brother on the staff of General Lee."

"Did you not inform me your family were loyalists?"

"Yes; it is true," earnestly, her foot tapping the floor, as though annoyed at such persistent questioning. "I have a father and brother in the King's service—but one is a renegade, and I—I—"

"You are what?"

"I am merely a woman, sir, unable to determine whether to finally become loyalist or rebel."

I looked gravely into her eyes until they fell, veiling their revelation of truth behind long lashes.

"Mistress Mortimer," I murmured, bending so close to her pink ear, I felt the soft touch of her hair on my lips, "you dissemble so charmingly as to even puzzle me. But if I leave you now, as you request, I must first have promise of welcome again."

"Then you mean to return—a prisoner? I am always merciful to the suffering."

"No; we are coming back to Philadelphia victors, and soon. I am not afraid to tell you. I have learned much to-day, and go back to report to Washington that the exchange of British commanders means the early evacuation of this city. When we meet again you will not be a lady of the Blended Rose, nor will I be wearing this uniform."

Her eyes sparkled brightly into mine, then dropped demurely.

"I—I rather like the colors you are wearing now, and am sure this dress is most becoming. I—I have a passion for masquerade."

"I recognize that, but have already discovered where I can read the truth beyond the masque—what is occurring now?"

She turned to look, attracted as I had been by the change and bustle about us. A few feet from where we stood conversing, large folding doors, previously concealed by draperies, were suddenly flung wide open, revealing a magnificent dining-hall. Before the crowd could recover from its first surprise, and surge that way, my eyes had taken in the full effect of the disclosure. It was a vast saloon, as I have since been informed, measuring two hundred and ten feet by forty, with a height of twenty-two feet, having three large alcoves on each side. The ceiling was the segment of a circle, the sides painted a light straw color, with vine leaves and festoons of flowers, some in bright, others in dark green. More than fifty large pier-glasses extended from floor to ceiling, reflecting the glitter of the tables, while a hundred branches of three lights each, and eighteen clusters of twenty-four, illumined the immense apartment, aided by three hundred wax tapers upon the snowy tables. These were already prepared for service, set with nearly five hundred covers, a large company of black slaves, attired in Oriental fashion, awaiting the coming of the guests. Sir William and his brother already led the way, the others pouring in as rapidly as the wide doors would permit. Dazzled by the magnificent spectacle I turned to my companion, unable to resist temptation. She must have instantly read the purpose in my face, for she grasped my sleeve.

"No; you must not think of remaining a moment longer. There will be a seat reserved for me, and Captain Grant is coming this way now. Something is wrong, I am sure; I have no time to explain, but promise me you will leave here at once—at once."

Her eyes, her words, were so insistent I could not refuse, although as I glanced about I felt convinced there was no danger in this assemblage, not a familiar face meeting mine. At the instant Grant came up, elbowing his way through the press, and staring insolently into my eyes, even as he bowed politely to the lady beside me.

"At least this is my privilege," he insisted, "unless there be another previous engagement of which I am ignorant."

"Oh, no," and she rested her hands on the green sleeve, smiling from his face into mine. "We were waiting for you to come. Good-night, Lieutenant Fortesque."

They had taken a step or two, when Grant halted, holding her arm tightly as he glanced back to where I stood.

"Would Lieutenant Fortesque spare me a moment after I have found the lady a seat?" he questioned politely.

"Gladly, if you do not keep me waiting too long."

"Then there will be no delay. Shall we say the parlor below?"

I bowed, conscious of the mute appeal in the lady's face, yet with no excuse for refusal.

"As well there as anywhere, sir."

Once again we bowed with all the punctilious ceremony of mutual dislike, and he whispered something into her ear as they disappeared in the stream of people. My cheeks burned with indignation at his cool insolence. What could it mean? Was he merely seeking a quarrel? or was there something else concealed behind this request? In either case I knew not how to act, and yet felt no inclination to avoid the meeting. Studying over the situation I pushed my way through the crowd across the floor of the ball-room. There were a few people still lingering on the stairs, but, except for the servants, the parlors below were deserted. I walked the length of one of the great rooms, and halted in front of a fireplace to await Grant's coming. I was eager to have this affair settled, and be off. I comprehended now the risk I had assumed by remaining so long, and began to feel the cords of entanglement drawing about me. There was a door opposite where I stood, and, staring toward it, I saw it open slightly, and, back in the darkness, the beckoning of a hand. Startled, yet realizing that it must mean me, I stepped closer, gripping the hilt of my sword, half suspecting treachery.

"Quick," and I recognized the deep contralto of the voice. "Don't stop to question; there is not a moment to lose."
