A few days later, Henri IV, in celebration of his bloodless victory over the Duc de Bouillon, made a sort of triumphal entry into Paris, where he was received with salvoes of artillery and loud acclamations from the populace. The effect of this ceremony, however, appears to have been somewhat spoiled by the extraordinary attitude assumed by the rebellious vassal whom he had just brought to heel, and who rode along bowing and smiling to the people who thronged the streets and the windows and roofs of the houses, for all the world as if he himself were the hero of the day and the object of all the acclamations.

“He [the King],” writes Bassompierre, “desired M. de Bouillon to march immediately before him, and this he did, but with such assurance and audacity, that it was impossible to decide whether it was the King who was leading him in triumph or he the King.”

Henri IV only remained a few days in Paris, and then went to Fontainebleau; but Bassompierre did not accompany him, being desirous of enjoying the society of Marie d’Entragues, of whom, since their reconciliation, he was more enamoured than ever.

Bassompierre’s conquest of Mlle. d’Entragues had naturally aroused a good deal of jealousy amongst the less fortunate admirers of that young lady, who were numerous and distinguished, and included both the King and the Duc de Guise. As yet, however, they had no actual proof of his bonne fortune, as the intrigue was conducted with unusual discretion. It was his habit, he tells us, to enter the house in the Rue de la Coutellière, where Marie lived with her mother, late at night, by a back entrance, “whereby I ascended to the third floor, which Madame d’Entragues had not furnished, and her daughter, by a secret staircase leading from her wardrobe, came to join me there, when her mother had fallen asleep.”

Henri IV, piqued by the assurances of several of Bassompierre’s rivals, and principally by Guise, that Marie d’Entragues made game of them all and preferred the handsome Lorrainer, gave orders, just before his departure for Fontainebleau, to have the house watched.

“As he was in love with Antragues, M. de Guise and several others also, who were all jealous of me, because they believed me to be on better terms with her than themselves, plotted together to have me spied upon, in order to discover if I entered her house, and if I saw her privately; and the King commanded those whom he had charged to watch it, to take their orders from M. de Guise and to report to him if they saw anything.”

The sequel was a most amusing comedy of errors.

A day or two later, Bassompierre, who had an assignation with his inamorata that night, happened to sup with the Grand Equerry, the Duc de Bellegarde. During the meal it came on to rain heavily, and, as he had come unprovided with a cloak, he borrowed one from his host, and, wrapped in this, made his way, at about eleven o’clock, to the Rue de la Coutellière, without noticing that the Cross of the Ordre du Saint-Esprit, of which none but Princes of the Blood, very great nobles, and Ministers of State, were members, was attached to the cloak. The spies posted around Madame d’Entragues’s house were more observant, and one of them at once hurried off to inform the Duc de Guise that they had just seen a young Knight of the Ordre du Saint-Esprit enter the house by a back door. Guise immediately sent two of his valets de chambre to identify the gentleman when he left, which did not happen until four o’clock in the morning. But Bassompierre caught sight of them before they saw him, and, recognising them as the duke’s servants, pulled his cloak over his face, though he had little hope of escaping detection, since he was well known to them both. The valets, however, deceived by the Cross of the Saint-Esprit, reported to their master that Mlle. d’Entragues’ midnight visitor was the Grand Equerry, since they were aware that there was no other Knight of the Order in Paris at the time in the least likely to have such a bonne fortune.

In the morning, Bassompierre wrote to Mlle. d’Entragues to inform her of the espionage of which he had been the object, and to urge her to be on her guard. On his side, the Duc de Guise went between nine and ten o’clock to the Grand Equerry’s house, but was told that Bellegarde had given directions that he could see no one until the evening, as he had been kept awake all night by violent toothache. This seemed to confirm his suspicions in regard to the Grand Equerry, since a man who had not returned from an assignation until four o’clock in the morning would naturally desire to sleep until late in the day; and chuckling at the thought of Bassompierre’s mortification when he learned that he had a successful rival, he made his way to that gentleman’s lodging.

Bassompierre, like Bellegarde, was still in bed when the duke arrived, but, having told the servants that he had come to see their master on a matter of urgency, he was conducted to his room.
