Iknow not, my dear child, if the adventure of Madame de Valcy is talked of at Fontainbleau, but this is the true story: Last Monday, the 20th of October, Madame de Valcy told her mother she should sup at the Palais royal, and about half past nine, she and the Countess de Germeuil sat out, and did not return till half past Three in the morning. The next day she told her mother she had supped there, and that, at Twelve o'clock they heard, from the room they were in, some delightful music; that Madame de Germeuil would not let her rest, till she consented to go down to the garden, where they staid about a quarter of an hour, and then they both returned home to Madame de Germeuil's house, where they drank tea together, while Madame de Germeuil undressed herself; and that in short they forgot the time till it was Three o'clock. The next evening the Chevalier de Herbain told Madame de Limours, that it was reported her daughter had been seen, with Madame de Germeuil, walking with Mons. de Creny and Mons. de L— from One o'clock till Three. Madame de Limours would not believe it, but the next day one of the servants, who attended Madame de Valcy, being much pressed by Madame de Limours, confessed that his Lady returned from the Palais royal at Eleven o'clock; that they went and undressed at Madame de Germeuil's, and then returned to the Palais royal, where they staid three hours in the garden. This affair has been made public by Mons. B—, who has been in love with Madame de Valcy these six months. He also supped at the Palais royal, and pretends to have heard Madame de Valcy make the appointment with Mons. de Creny. Mons. de B— went into the garden with two of his friends, and there saw the two Gentlemen, after waiting half an hour, joined by Madame de Valcy and Madame de Germeuil, and walk with them till the hour I mentioned.
