Langerac, the States' Ambassador in Paris, was the very reverse of his predecessor, the wily, unscrupulous, and accomplished Francis Aerssens. The envoys of the Republic were rarely dull, but Langerac was a simpleton. They were renowned for political experience, skill, familiarity with foreign languages, knowledge of literature, history, and public law; but he was ignorant, spoke French very imperfectly, at a court where not a human being could address him in his own tongue, had never been employed in diplomacy or in high office of any kind, and could carry but small personal weight at a post where of all others the representative of the great republic should have commanded deference both for his own qualities and for the majesty of his government. At a period when France was left without a master or a guide the Dutch ambassador, under a becoming show of profound respect, might really have governed the country so far as regarded at least the all important relations which bound the two nations together. But Langerac was a mere picker-up of trifles, a newsmonger who wrote a despatch to-day with information which a despatch was written on the morrow to contradict, while in itself conveying additional intelligence absolutely certain to be falsified soon afterwards. The Emperor of Germany had gone mad; Prince Maurice had been assassinated in the Hague, a fact which his correspondents, the States-General, might be supposed already to know, if it were one; there had been a revolution in the royal bed-chamber; the Spanish cook of the young queen had arrived from Madrid; the Duke of Nevers was behaving very oddly at Vienna; such communications, and others equally startling, were the staple of his correspondence.

Still he was honest enough, very mild, perfectly docile to Barneveld, dependent upon his guidance, and fervently attached to that statesman so long as his wheel was going up the hill. Moreover, his industry in obtaining information and his passion for imparting it made it probable that nothing very momentous would be neglected should it be laid before him, but that his masters, and especially the Advocate, would be enabled to judge for themselves as to the attention due to it.

"With this you will be apprised of some very high and weighty matters," he wrote privately and in cipher to Barneveld, "which you will make use of according to your great wisdom and forethought for the country's service."

He requested that the matter might also be confided to M. van der Myle, that he might assist his father-in-law, so overburdened with business, in the task of deciphering the communication. He then stated that he had been "very earnestly informed three days before by M. du Agean"—member of the privy council of France—"that it had recently come to the King's ears, and his Majesty knew it to be authentic, that there was a secret and very dangerous conspiracy in Holland of persons belonging to the Reformed religion in which others were also mixed. This party held very earnest and very secret correspondence with the factious portion of the Contra-Remonstrants both in the Netherlands and France, seeking under pretext of the religious dissensions or by means of them to confer the sovereignty upon Prince Maurice by general consent of the Contra-Remonstrants. Their object was also to strengthen and augment the force of the same religious party in France, to which end the Duc de Bouillon and M. de Chatillon were very earnestly co-operating. Langerac had already been informed by Chatillon that the Contra-Remonstrants had determined to make a public declaration against the Remonstrants, and come to an open separation from them.

"Others propose however," said the Ambassador, "that the King himself should use the occasion to seize the sovereignty of the United Provinces for himself and to appoint Prince Maurice viceroy, giving him in marriage Madame Henriette of France." The object of this movement would be to frustrate the plots of the Contra-Remonstrants, who were known to be passionately hostile to the King and to France, and who had been constantly traversing the negotiations of M. du Maurier. There was a disposition to send a special and solemn embassy to the States, but it was feared that the British king would at once do the same, to the immense disadvantage of the Remonstrants. "M. de Barneveld," said the envoy, "is deeply sympathized with here and commiserated. The Chancellor has repeatedly requested me to present to you his very sincere and very hearty respects, exhorting you to continue in your manly steadfastness and courage." He also assured the Advocate that the French ambassador, M. du Maurier, enjoyed the entire confidence of his government, and of the principal members of the council, and that the King, although contemplating, as we have seen, the seizure of the sovereignty of the country, was most amicably disposed towards it, and so soon as the peace of Savoy was settled "had something very good for it in his mind." Whether the something very good was this very design to deprive it of independence, the Ambassador did not state. He however recommended the use of sundry small presents at the French court—especially to Madame de Luynes, wife of the new favourite of Lewis since the death of Concini, in which he had aided, now rising rapidly to consideration, and to Madame du Agean—and asked to be supplied with funds accordingly. By these means he thought it probable that at least the payment to the States of the long arrears of the French subsidy might be secured.

Three weeks later, returning to the subject, the Ambassador reported another conversation with M. du Agean. That politician assured him, "with high protestations," as a perfectly certain fact that a Frenchman duly qualified had arrived in Paris from Holland who had been in communication not only with him but with several of the most confidential members of the privy council of France. This duly qualified gentleman had been secretly commissioned to say that in opinion of the conspirators already indicated the occasion was exactly offered by these religious dissensions in the Netherlands for bringing the whole country under the obedience of the King. This would be done with perfect ease if he would only be willing to favour a little the one party, that of the Contra-Remonstrants, and promise his Excellency "perfect and perpetual authority in the government with other compensations."

The proposition, said du Agean, had been rejected by the privy councillors with a declaration that they would not mix themselves up with any factions, nor assist any party, but that they would gladly work with the government for the accommodation of these difficulties and differences in the Provinces.

"I send you all this nakedly," concluded Langerac, "exactly as it has been communicated to me, having always answered according to my duty and with a view by negotiating with these persons to discover the intentions as well of one side as the other."

The Advocate was not profoundly impressed by these revelations. He was too experienced a statesman to doubt that in times when civil and religious passion was running high there was never lack of fishers in troubled waters, and that if a body of conspirators could secure a handsome compensation by selling their country to a foreign prince, they would always be ready to do it.

But although believed by Maurice to be himself a stipendiary of Spain, he was above suspecting the Prince of any share in the low and stupid intrigue which du Agean had imagined or disclosed. That the Stadholder was ambitious of greater power, he hardly doubted, but that he was seeking to acquire it by such corrupt and circuitous means, he did not dream. He confidentially communicated the plot as in duty bound to some members of the States, and had the Prince been accused in any conversation or statement of being privy to the scheme, he would have thought himself bound to mention it to him. The story came to the ears of Maurice however, and helped to feed his wrath against the Advocate, as if he were responsible for a plot, if plot it were, which had been concocted by his own deadliest enemies. The Prince wrote a letter alluding to this communication of Langerac and giving much alarm to that functionary. He thought his despatches must have been intercepted and proposed in future to write always by special courier. Barneveld thought that unnecessary except when there were more important matters than those appeared to him to be and requiring more haste.
