"Monsieur, you are Pierre Dubois, a Frenchman in London."

"Miserable fate! Must I be?" complained d'Erquy, to general amusement.

"You must. But you need not sit down yet, for you have not yet made the acquaintance of Signore Punchinello. Instead, you wander about the city like a lost soul, trying to find a decent loaf of bread. Now! Places, everyone!" and she walked back into the Petit Salon, where the Lyon table had been supplied with quills, ink, and paper.

"Monsieur le contrôleur-général, give your silver—which is to say, France's silver—to Lothar the Banker."

"Monsieur, s'il vous plaît," said Pontchartrain, shoving the pile across the table.

"Merci beaucoup, monsieur," said Étienne, a bit uncertainly.

"You must give him more than polite words! Write out the amount, and the word ‘Londres,' and a time, say five minutes in the future."

Étienne dutifully took up his quill and did as he was told, putting down "half past three," as the clock in the corner was currently reading twenty-five minutes past. "To the contrôleur-général give it," said Eliza. "And now you, contrôleur-général, write an address on the back, thus: ‘To Monsieur Pierre Dubois, London.' Meanwhile you, Lothar, must write an avisa addressed to Signore Punchinello in London, containing the same information as is in the Bill."

"The Bill?"

"The document you have given to the contrôleur-général is a Bill of Exchange."

Pontchartrain had finished addressing the Bill, and so Mercury snatched it out of his hand and pranced out of the room and gave it to "Pierre Dubois," who had been watching, bemused, from the doorway. Then she returned to "Lothar," who was writing out the avisa with a good deal more formality than was called for. Mercury jerked it out from under the quill.

"Good heavens, I haven't even finished the Apology yet."

"You must learn better to inhabit the rôle of Lothar. He would not be so discursive," said Mercury, and wafted the avisa out of the room to "Signore Punchinello." "In truth, there would be two or even three copies of the Bill and the avisa both, sent by separate couriers," said Mercury, "but to prevent the masque from becoming tedious we shall only use one. Signore Punchinello! You said earlier you did not know how to play your rôle; but I tell you now that you need only know how to read, and be capable of recognizing Lothar's handwriting. Do you? (The correct answer is ‘Yes, Mercury.')"

"Yes, Mercury."

"Monsieur Dubois, I think you can guess what to do."

Indeed, "Pierre Dubois" now helped himself to a seat at the London table across from "Signore Punchinello," and presented the bill.

"Now, signore," said Eliza to Madame de Bearsul, "you must compare what is written on Monsieur Dubois's Bill to what is in the avisa."

"They are the same," answered "Punchinello."

"Do they appear to have been written in the same hand?"

"Indeed, Mercury, the hands are indistinguishable."

"What time is it?"

"By yonder clock, twenty-eight minutes past the hour of three."

"Then take up yonder quill and write ‘accepted' across the face of the Bill, and sign your name to it."

Madame de Bearsul did so, and then, getting into the spirit of the thing, opened up her backgammon-set and began to count out pieces.

"Not yet!" said Mercury. "That is, it's fine for you to count them out, and make sure you have enough. But good banker that you are, you'll not give them to Monsieur Dubois until the Bill has come due."

But they only had to wait for a few more seconds before the clock bonged twice, signifying half past three; then the backgammon pieces were pushed across the table into the waiting hands of "Pierre Dubois."

"Voilà!" announced Mercury to the audience, which by this point numbered above twenty party-guests. "The first act of our masque draws to a happy ending. Monsieur le contrôleur-général has transferred silver from Lyon to London at no risk, and even converted it to English silver pennies along the way, with practically no effort! All by invoking the supernatural powers of Mercury." And Eliza took a little curtsey, and basked for a few moments in the applause of her guests.

ENTR'ACTE

"I am the contrôleur-général of France, madame; I know what a Bill of Exchange is." This from Pontchartrain, who had maneuvered her into a niche and was muttering out the side of his mouth with uncharacteristic harshness.

"And I know your title and your powers, monsieur," said Eliza.

"Then if you have more to say concerning the Mint, I would fain hear it—"

"In good time, monsieur!"

Madame de Bearsul was pitching a minor scene at "London." Petulance was something she did well. "I have given up my coins to Monsieur Dubois—in exchange for what!?"

"Bills written in the hand of a banker who is Ditta di Borsa—as good as money."

"But they are not money!"

"But Signore Punchinello, you may turn them into money, or other things of value, by taking them to an office of Lothar's concern."

"But he is in Lyon, and I am stuck in London!"

"Actually he is in Leipzig—but never mind, for he maintains an office in London. After the Usurper took the throne, any number of bankers from Amsterdam crossed the sea and established themselves there—"

"Wait! First Lothar was in Lyon—then Leipzig—then Amsterdam—now London?"

"It is all one thing, for Mercury touches all of these places on his rounds." And Eliza thrust an arm into a boozy-smelling phalanx of young men and dragged forth a young Lavardac cousin and bade him sit down near the backgammon table. "This is Lothar's factor in London." She grabbed a second young man who had been snickering at the fate of the first, and stationed him in the short gallery that joined the two salons, calling this Amsterdam.

"I must register an objection! (Pardon me for speaking directly, but I am trying to inhabit the rôle of an uncouth Saxon banker)," said Eliza's husband.

"And you are doing splendidly, my love," said Eliza. "What is your objection?"

"Unless these chaps of mine in Amsterdam and London are titled nobility, which I'm led to believe is generally not the case—"

"Indeed not, Étienne."

"Well, if they are not of independent means, it would seem to suggest that—" and here Étienne colored slightly again, "forgive me, but must I—" and he balked until both Eliza and Pontchartrain had made encouraging faces at him, "well, pay them—" he half-swallowed the dreadful word—"I don't know, so that they could—buy—food and whatnot, presuming that's how they get it? For I don't phant'sy they would have their own farms, living as they do in cities."

"You must pay them!" Eliza said loud and clear.

Étienne winced. "Well, it hardly seems worth all the bother for me to be taking in silver here, and sending Bills to one place, and avisas to another, all so that I can end up handing the silver over to Signore Punchinello in the end." He scanned nearby faces uncertainly, taking a sort of poll—but everyone was nodding profoundly, as if the duc d'Arcachon had made a telling point. All of those faces now turned towards Eliza.

"You get to keep some of the money," Eliza said.

Everyone gasped as if she had jerked the veil from a statue of solid gold.

"Oh, well, that puts it in a whole new light!" exclaimed Étienne.

"The amount collected by Pierre Dubois in London was not quite as large as what I gave to you," said Pontchartrain. He then turned to look at Eliza. "But, madame, I live in Paris."

Eliza went into the opposite corner of the Petit Salon and patted a gilded harpsichord. Pontchartrain excused himself from Lyon and sat before it. Then, to amuse himself and to provide incidental music for the second act of the masque, he began to pick out an air by Rameau.

Eliza beckoned to a middle-aged Count dressed in the uniform of a galley-captain. Until recently, he and a friend had been playing at billiards. "You are Monsieur Samuel Bernard, moneylender to le Roi."
