There his thoughts checked on a sudden. As in a flash of revelation, he saw the meaning of Lady Carlisle’s oddly contradictory behaviour. The jade had fooled him. It was she who had stolen the riband. He sat down again, his head in his hands, and swiftly, link by link, he pieced together a complete chain. Almost as swiftly he decided upon the course of action which he must adopt so as to protect the Queen of France’s honour. He was virtually the ruler of England, master in these islands of an almost boundless power. That power he would exert to the full this very night to thwart those enemies of his own and of the Queen’s, who worked so subtly in concert. Many would be wronged, much harm would be done, the liberties of some thousands of freeborn Englishmen would be trampled underfoot. What did it matter? It was necessary that his Grace of Buckingham should cover up an indiscretion. “Set ink and paper yonder,” he bade his gaping valet. “Then go call M. Gerbier. Rouse Lacy and Thom, and send them to me at once, and leave word that I shall require a score of couriers to be in the saddle and ready to set out in half an hour.” Bewildered, the valet went off upon his errand. The Duke sat down to write. And next morning English merchants learnt that the ports of England were closed by the King’s express command—delivered by his minister, the Duke of Buckingham—that measures were being taken—were already taken in all southern ports—so that no vessel of any kind should leave the island until the King’s further pleasure were made known. Startled, the people wondered was this enactment the forerunner of war. Had they known the truth, they might have been more startled still, though in a different manner. As swiftly as couriers could travel—and certainly well ahead of any messenger seeking escape overseas—did this blockade spread, until the gates of England were tight locked against the outgoing of those diamond studs which meant the honour of the Queen of France. And meanwhile a diamond-cutter was replacing the purloined stones by others, matching them so closely that no man should be able to say which were the originals and which the copies. Buckingham and Gerbier between them guided the work. Soon it was accomplished, and a vessel slipped down the Thames, allowed to pass by those who kept close watch to enforce the royal decree, and made sail for Calais, which was beginning to manifest surprise at this entire cessation of traffic from England. From that vessel landed Gerbier, and rode straight to Paris, carrying the Queen of France the duplicate studs, which were to replace those which she had sent to Buckingham. Twenty-four hours later the ports of England were unsealed, and commerce was free and unhampered once more. But it was twenty-four hours too late for Richelieu and his agent, the Countess of Carlisle. His Eminence deplored a fine chance lost through the excessive power that was wielded in England by the parvenu.
