How could a Prince of the House of Rohan, and a Grand Almoner of France, ever think that the Queen would sign Marie Antoinette de France?
Everybody knows that queens sign only by their baptismal names.

But, monsieur," pursued the King, handing him a copy of his letter to Baehmer, "have you ever written such a letter as this ?" Having glanced over it, the Cardinal said, "I do not remember having written it." "But what if the original, signed by yourself, were shown to you ?" "If the letter be signed by myself it is genuine." He was extremely confused, and repeated several times, "I have been deceived, Sire; I will pay for the necklace.

I ask pardon of your Majesties." "Then explain to me," resumed the King, "the whole of this enigma.

I do not wish to find you guilty; I had rather you would justify yourself.
Account for all the manoeuvres with Baehmer, these assurances and these letters." The Cardinal then, turning pale, and leaning against the table, said, "Sire, I am too much confused to answer your Majesty in a way--" "Compose yourself, Cardinal, and go into my cabinet; you will there find paper, pens, and ink,--write what you have to say to me." The Cardinal went into the King's cabinet, and returned a quarter of an hour afterwards with a document as confused as his verbal answers had been.

The King then said, "Withdraw, monsieur." The Cardinal left the King's chamber, with the Baron de Breteuil, who gave him in custody to a lieutenant of the Body Guard, with orders to take him to his apartment.
