About this time Lauzun, soon to become cousin-german to the King, solicited the distinguished post of Grand Master of the Artillery. Already he commanded the Dragoons, and was captain of the hundred gentlemen pensioners who guarded the person of the Sovereign; but this was not enough. The King readily promised him the appointment; but time went on, and no warrant came. Lauzun grew uneasy—specially as each time he recalled the subject the King evidently evaded it. What did this mean? Who was his enemy? He spoke to the favourite, Madame de Montespan, although he was well aware he had given her good cause for hating him. Madame de Montespan, with the most winning smiles, promised him her assistance. Still no warrant came. Again Lauzun ventured to recall his promise to the King at his lever, while handing him his feathered hat and cane. Louis turned away his head, addressed the Duc de Roquelaure, and affected not to hear him. There was treachery somewhere! Lauzun shrewdly suspected Madame de Montespan. He would know for certain that very day, and if it were so he would unmask her. He offered a heavy bribe to one of her confidential attendants, well known to him in the days of their _liaison_, and prevailed on her to introduce him into the saloon, where the King would visit Madame de Montespan before supper, that very afternoon. Louis, who told his mistress everything, and consulted her about all important appointments, would be sure to mention Lauzun's renewed application of that morning. At all events Lauzun would chance it. He knew the lady was from home, having seen her start, in company with the Queen and Mademoiselle de Montpensier, for a drive to Saint-Cloud. He had handed his betrothed into the royal coach. No sooner had they started than Lauzun was admitted into Madame de Montespan's apartments by her friendly attendant. She assisted him in his arrangements, and finally concealed him under a large couch covered with fine tapestry, on which Madame de Montespan usually sat. It was an undignified proceeding. He had to divest himself of his periwig and plumed hat, take off his richly embroidered satin coat, tuck up his shirt sleeves, and crouch upon his hands and knees upon the dusty floor. But these are trifles to a man bent upon revenge! Shortly before the hour of supper, which their Majesties eat in public, Lauzun recognised Madame de Montespan's voice within her boudoir. Then he heard steps approaching. He could swear to the King's solemn tread and the sound of his cane tapping on the floor. Almost before he could settle himself in the best position for listening the King was announced. At the same moment Madame de Montespan entered from her boudoir on the other side of the saloon. He heard her advance to the door and receive the King. She kissed his hand; Louis saluted her on both cheeks, and led her to the couch under which Lauzun lay concealed.
