The other instance in which Charles was recalcitrant was my Lady Castlemaine's fondness for the "invincible Jermyn," with his big head and little legs and forced wit. As the records of the period quite fail to convey the charm this vain, shallow dandy exercised on all the women of the Court, we are inclined to agree with the King that he was a creature to be despised. But Lady Castlemaine, like the rest of her sex, thought differently. This was one of the rare occasions when the termagant was strangely chary about giving offence. To cover up one's tracks at Whitehall was very difficult, and Lady Castlemaine was only partially successful. The arrival of Frances Stuart at Court gave her an opportunity to practise her powers of dissimulation. Lady Castlemaine professed a great friendship for the beauty and had her to sleep in the same bed, not so much as a compliment on the part of my lady as a ruse to throw Charles off the scent. For when the King came, as was his habit, every morning and nearly every night, to visit Lady Castlemaine he found La Belle Stuart in bed beside her ladyship. But while this friendship tended to extinguish Charles's jealousy of Jermyn, it finished by firing my Lady Castlemaine's of Miss Stuart. It is not here that we shall relate in full the amusing particulars of the game of cross-purposes, of which the prize was sexual emotion, that to the ribald delight of the town and the more decorous gratification of Mr. Pepys now took place. The shrew had to fight the prude for her position, her plunder, and her royal paramour. From being friends the rival beauties became deadly enemies. The quarrel was taken up by their servants; the nurses of the mistress's bastards assaulted the maids of the prude; once the King had to leave the Council of State to make peace!

All her powers of coarse vituperation, all her powers of intrigue, all her knowledge of the King's character were brought into play by Lady Castlemaine. She dished her rival, but it is a marvel, with the strange means she employed, that she was not utterly ruined. The secret of her success is to be found, we think, in that she was fighting not for possession of the King's affections, she cared nothing about them, but for the possession of his influence.

It is to be borne in mind that this Stuart-Castlemaine-Jermyn affair continued for nearly five years. Once during this time, on some slighting words from the King, Lady Castlemaine packed her boxes and trunks and, swearing she had shaken the dust of the Court from her feet, quitted the palace for Richmond. But in spite of Miss Stuart, or perhaps on account of her prudery, Charles, after a couple of days, missed the termagant, and went a-hunting in her neighbourhood, to the amusement of the Court. The next day my Lady Castlemaine was back at Whitehall, but before she came she made the King implore her on his knees! The reconciliation was, however, of short duration. The talk of the town was of nothing but the wrangling that went on in the royal palace between the mistresses. Pepys's diary is for the time a thermometer registering the rise and fall of the temperature of a mercurial royal favour and its effect on my Lady Castlemaine's looks and moods.

Had her beautiful prudish rival possessed less virtue and more wit Lady Castlemaine's star would have set long before it did. But she finally ruined La Belle Stuart in the same contemptible, unprincipled fashion as Buckingham later ruined herself. Warned by the pimps of the back-stairs, whom she took care to secure to her interest, she was able to notify Charles in time for him to surprise Miss Stuart in a situation which deprived her of his regard. With the prude's elopement from Whitehall the day after this adventure, Lady Castlemaine's position was more secure than ever, and her reign continued as before, punctuated with infidelities and Billingsgate quarrels.

In the morning of the Restoration decency was not wholly flung to the winds. Then when my Lady Castlemaine presented her lord with a son, the new-born babe was smuggled out of her bed secretly, and "carried off by a coachman under his cloak," to be publicly acknowledged by the King years later when the sun of the Restoration was at its zenith. It is said that several dukes came into the world in this mysterious fashion. But as time passed the coming of a bastard was noised about the Court and the coffee-houses long before he arrived. During the Great Plague, when the Court was at Oxford, Pepys states that "every boy in the streets openly cries, 'The King can't go away till my Lady Castlemaine be ready to come along with him.'" On this occasion the poor Queen, who, under the mask of friendship which she wore even in private, studied revenge for the insults she received from this brazen courtezan, called upon her lady of the bedchamber to fulfil her duties, and my Lady Castlemaine, scarcely able to leave her bed, had to mount and ride in Catherine's suite.

Another time she contented herself with laughing at Lady Castlemaine's jealousy of La Belle Stuart. Yet another, the King himself revenged her. Overhearing his mistress one day making a slighting remark of the Queen, Charles burst into one of his rare fits of anger and ordered the woman to leave Whitehall forthwith. Lady Castlemaine went off imperiously enough, but took the precaution to leave her baggage behind her. At the end of three days, hearing nothing from him, she became alarmed and wrote him submissively to ask for permission to send for her things. He told her she might come in person and fetch them if she wished them, and the quarrel ended as usual in a reconciliation. Her hold over him seemed magical—a hold the secret of which, one would say, was the fearlessness of her abuse. Under that terrible lash Charles cowered to the end like a whipped dog.

During her struggle for supremacy with the Stuart, when even the most witless of frailties would have cunningly manœuvred the whole artillery of flattery, kisses, smiles, sighs, and tears, Lady Castlemaine exploded her vituperative bombs in the royal presence, and taunted the King like a poissarde. Nor, what is perhaps more remarkable, in the duel of these Restoration Brunhildas and Fredregondes for Charles's heart, did either one or the other subject her private inclinations to interest.

When the Queen was supposed to be dying and the gamesters of the Court were backing Miss Stuart for her place, Lady Castlemaine continued her intrigue half-openly, half-secretly with Jermyn. On the authority of a Mr. Cooling, from whom Pepys was in the habit of pumping the gossip of the Court when that gentleman was primed with wine, history learns that Charles, venturing a little cynical raillery on the subject of Jermyn, whom he considered more despicable a rival than Goodman or Hall, remarked that though always willing to oblige the ladies, he could hardly be expected to father all the babes about to be born at Whitehall. To which Lady Castlemaine, who saw an allusion to herself in the remark, "made a slight puh at him with her mouth." In this instance, however, Charles proved very inconsiderate of my Lady Castlemaine's state of health. Whereupon with curses and tears of rage she rushed from the palace to a friend's house in Pall Mall, swearing that "she will have it christened in the Chapel at Whitehall and owned for the King's; or she will bring it into Whitehall gallery and dash the brains of it out before the King's face!"

But whether it was because he was afraid that this woman, unique in the annals of palace prostitution, was capable of putting her Medea-like vengeance into effect, or from the more likely fear of her threat to publish his letters, Charles followed her and prayed her on his knees to return. From one of his Povys, or Fenns, or Coolings the prurient Mr. Pepys learns that my Lady Castlemaine allowed herself to be persuaded to yield, but "not as a mistress, for she scorned him, but as a tyrant to command him! And so she is come to-day, when one would think his mind should be full of some other cares, having this morning broken up such a Parliament with so much discontent, and so many wants upon him, and but yesterday heard such a sermon against adultery."
