Carford insisted that he could take the Duke alone; I would not budge.

My lord grew offensive, hinting of busybodies who came between the Duke and his friends. Pushed hard, I asked the Duke himself if I should leave him. He bade me stay, swearing that I was an honest fellow and no Papist, as were some he knew. I saw Carford start; his Grace saw nothing save the entrance of his chamber, and that not over-plainly. But we got him in, and into a seat, and the door shut. Then he called for more wine, and Carford at once brought it to him and pledged him once and again, Monmouth drinking deep.

"He's had more than he can carry already," I whispered. Carford turned straight to the Duke, crying, "Mr Dale here says that your Grace is drunk." He made nothing by the move, for the Duke answered good-humouredly,

"Truly I am drunk, but in the legs only, my good Simon. My head is clear, clear as daylight, or the----" He looked round cunningly, and caught each of us by the arm. "We're good Protestants here?" he asked with a would-be shrewd, wine-muddled glance.

"Sound and true, your Grace," said Carford. Then he whispered to me, "Indeed I think he's ill. Pray run for the King's physician, Mr Dale."

"Nay, he'd do well enough if he were alone with me. If you desire the physician's presence, my lord, he's easy to find."

I cared not a jot for Carford's anger, and was determined not to give ground. But we had no more time for quarrelling.

"I am as loyal--as loyal to my father as any man in the kingdom," said the Duke in maudlin confidence. "But you know what's afoot?"

"A new war with the Dutch, I'm told, sir," said I.

"A fig for the Dutch! Hush, we must speak low, there may be Papists about. There are some in the Castle, Carford. Hush, hush! Some say my uncle's one, some say the Secretary's one. Gentlemen, I--I say no more.

Traitors have said that my father is----"

Carford interrupted him.

"Don't trouble your mind with these slanders, sir," he urged.

"I won't believe it. I'll stand by my father. But if the Duke of York--But I'll say no more." His head fell on his breast. But in a moment he sprang to his feet, crying, "But I'm a Protestant. Yes, and I'm the King's son." He caught Carford by the arm, whispering, "Not a word of it. I'm ready. We know what's afoot. We're loyal to the King; we must save him. But if we can't--if we can't, isn't there one who--who----?"

He lost his tongue for an instant. We stood looking at him, till he spoke again. "One who would be a Protestant King?"

He spoke the last words loud and fiercely; it was the final effort, and he sank back in his chair in a stupor. Carford gave a hasty glance at his face.

"I'll go for the physician," he cried. "His Grace may need blood-letting."

I stepped between him and the door as he advanced.

"His Grace needs nothing," said I, "except the discretion of his friends. We've heard foolish words that we should not have heard to-night, my lord."

"I am sure they're safe with you," he answered.

"And with you?" I retorted quickly.

He drew himself up haughtily.

"Stand aside, sir, and let me pa.s.s."

"Where are you going?"

"To fetch the physician. I'll answer none of your questions."

I could not stop him without an open brawl, and that I would not encounter, for it could lead only to my own expulsion. Yet I was sure that he would go straight to Arlington, and that every word the Duke had spoken would be carried to York, and perhaps to the King, before next morning. The King would be informed, if it were thought possible to prejudice him against his son; York, at least, would be warned of the mad scheme which was in the young Duke's head. I drew aside and with a surly bow let Carford pa.s.s. He returned my salutation with an equal economy of politeness, and left me alone with Monmouth, who had now sunk into a heavy and uneasy sleep. I roused him and got him to bed, glad to think that his unwary tongue would be silent for a few hours at least.

Yet what he had said brought me nearer to the secret and the mystery.

There was indeed more afoot than the war with the Dutch. There was, if I mistook not, a matter that touched the religion of the King. Monmouth, whose wits were sharp enough, had gained scent of it; the wits went out as the wine went in, and he blurted out what he suspected, robbing his knowledge of all value by betraying its possession. Our best knowledge lies in what we are not known to know.

I repaired, thoughtful and disturbed, to my own small chamber, next the Duke's; but the night was fine and I had no mind for sleep. I turned back again and made my way on to the wall, where it faces towards the sea. The wind was blowing fresh and the sound of the waves filled my ears. No doubt the same sound hid the noise of my feet, for when I came to the wall, I pa.s.sed unheeded by three persons who stood in a group together. I knew all and made haste to pa.s.s by; the man was the King himself, the lady on his right was Mistress Barbara; in the third I recognised Madame's lady, Louise de Querouaille. I proceeded some distance farther till I was at the end of the wall nearest the sea.

There I took my stand, looking not at the sea but covertly at the little group. Presently two of them moved away; the third curtseyed low but did not accompany them. When they were gone, she turned and leant on the parapet of the wall with clasped hands. Drawn by some impulse, I moved towards her. She was unconscious of my approach until I came quite near to her; then she turned on me a face stained with tears and pale with agitation and alarm. I stood before her, speechless, and she found no words in which to address me. I was too proud to force my company on her, and made as though to pa.s.s with a bow; but her face arrested me.

"What ails you, Mistress Barbara?" I cried impetuously. She smoothed her face to composure as she answered me:

"Nothing, sir." Then she added carelessly, "Unless it be that sometimes the King's conversation is too free for my liking."

"When you want me, I'm here," I said, answering not her words but the frightened look that there was in her eyes.

For an instant I seemed to see in her an impulse to trust me and to lay bare what troubled her. The feeling pa.s.sed; her face regained its natural hue, and she said petulantly,

"Why, yes, it seems fated that you should always be there, Simon, yet Betty Nasroth said nothing of it."

"It may be well for you that I'm here," I answered hotly; for her scorn stirred me to say what I should have left unsaid.

I do not know how she would have answered, for at the moment we heard a shout from the watchman who stood looking over the sea. He hailed a boat that came prancing over the waves; a light answered his signal. Who came to the Castle? Barbara's eyes and mine sought the ship; we did not know the stranger, but he was expected; for a minute later Darrell ran quickly by us with an eager look on his face; with him was the Count d'Albon, who had come with Madame, and Depuy, the Duke of York's servant. They went by at the top of their speed and in visible excitement. Barbara forgot her anger and haughtiness in fresh girlish interest.

"Who can it be?" she cried, coming so near to me that her sleeve touched mine, and leaning over the wall towards where the ship's black hull was to be seen far below in the moonlight by the jetty.

"Doubtless it's the gentleman whom Madame expects," said I.

Many minutes pa.s.sed, but through them Barbara and I stood silent side by side. Then the party came back through the gate, which had been opened for them. Depuy walked first, carrying a small trunk; two or three servants followed with more luggage; then came Darrell in company with a short man who walked with a bold and confident air. The rest pa.s.sed us, and the last pair approached. Now Darrell saw Mistress Barbara and doffed his hat to her. The new-comer did the like and more; he halted immediately opposite to us and looked curiously at her, sparing a curious glance for me. I bowed; she waited unmoved until the gentleman said to Darrell,

"Pray present me."

"This, madame," said Darrell, in whose voice there was a ring of excitement and tremulous agitation, "is M. de Perrencourt, who has the honour of serving Her Royal Highness the d.u.c.h.ess. This lady, sir, is Mistress Barbara Quinton, maid of honour to the d.u.c.h.ess of York, and now in attendance on Madame."

Barbara made a curtsey, M. de Perrencourt bowed. His eyes were fixed on her face; he studied her openly and fearlessly, yet the regard was difficult to resent, it was so calm, a.s.sured, and dignified. It seemed beyond challenge, if not beyond reproach. I stood by in silence, angry at a scrutiny so prolonged, but without t.i.tle to interfere.

"I trust, madame, that we shall be better acquainted," he said at last, and with a lingering look at her face pa.s.sed on. I turned to her; she was gazing after him with eager eyes. My presence seemed forgotten; I would not remind her of it; I turned away in silence, and hastened after Darrell and his companion. The curve of the wall hid them from my sight, but I quickened my pace; I gained on them, for now I heard their steps ahead; I ran round the next corner, for I was ablaze with curiosity to see more of this man, who came at so strange an hour and yet was expected, who bore himself so loftily, and yet was but a gentleman-in-waiting as I was. Round the next corner I should come in sight of him. Round I went, and I came plump into the arms of my good friend Darrell, who stood there, squarely across the path!

"Whither away, Simon?" said he coldly.

I halted, stood still, looked him in the face. He met my gaze with a calm, self-controlled smile.

"Why," said I, "I'm on my way to bed, Darrell. Let me pa.s.s, I beg you."

"A moment later will serve," said he.

"Not a moment," I replied testily, and caught him by the arm. He was stiff as a rock, but I put out my strength and in another instant should have thrown him aside. But he cried in a loud angry voice,

"By the King's orders, no man is to pa.s.s this way."

Amazed, I fell back. But over his head, some twenty yards from us, I saw two men embracing one another warmly. n.o.body else was near; Darrell's eyes were fixed on me, and his hand detained me in an eager grasp. But I looked hard at the pair there ahead of me; there was a cloud over the moon now, in a second it pa.s.sed. The next moment the two had turned their backs and were walking off together. Darrell, seeing my fixed gaze, turned also. His face was pale, as if with excitement, but he spoke in cool, level tones.

"It's only M. Colbert greeting M. de Perrencourt," said he.

"Ah, of course!" I cried, turning to him with a smile. "But where did M.
