If there was such a plot it is not at all unlikely that Overbury knew of it. If there was need of such a scheme to bolster the nullity petition it would have had to be evolved while the petition was being planned--that is, a month or two before the commission went first into session. At that time Overbury was still Rochester's secretary, still Rochester's confidant; and if such a scheme had been evolved for getting over an obstacle so fatal to the petition's success it was not in Rochester's nature to have concealed it from Overbury, the two men still being fast friends. Indeed, it may have been Overbury who pointed out the need there would be for the Countess to undergo physical examination, and it may have been on the certainty that her ladyship could not do so that Overbury rested so securely--as he most apparently did, beyond the point of safety--in the idea that the suit was bound to fail. It is legitimate enough to suppose, along this hypothesis, that this substitution plot was the very matter on which the two men quarrelled. That Overbury had knowledge of some such essential secret as this is manifest in the enmity towards the man which Lady Essex exhibited, even when he lay, out of the way of doing harm, in the Tower. It is hard to believe that an innocent girl of twenty, conscious of her virgin chastity, in mere fear of scandal which she knew would be baseless, could pursue the life of a man with the venom that, as we shall presently see, Frances Howard used towards Overbury through Mrs Turner. V As a preliminary to his marriage with Frances Howard, Rochester was created Earl of Somerset, and had the barony of Brancepeth bestowed on him by the King. Overbury was three months in his grave when the marriage was celebrated in the midst of the most extravagant show and entertainment. The new Earl's power in the kingdom was never so high as at this time. It was, indeed, at its zenith. Decline was soon to set in. It will not serve here to follow the whole process of decay in the King's favour that Somerset was now to experience. There was poetic justice in his downfall. With hands all about him itching to bring him to the ground, he had not the brain for the giddy heights. If behind him there had been the man whose guidance had made him sure-footed in the climb he might have survived, flourishing. But the man he had consigned to death had been more than half of him, had been, indeed, his substance. Alone, with the power Overbury's talents had brought him, Somerset was bound to fail. The irony of it is that his downfall was contrived by a creature of his own raising.
