“Yes. The only nobility who suffer the likes of you, or of me, to come within a mile of them, are those exceedingly peculiar few who (God help them!) have taken an interest in Natural Philosophy. They used to be more numerous, but now I can count them on the fingers of a hand: Eliza, Sophie, and Sophie Charlotte. Those are the only ones we get to talk to. They are desirous of exposing their young ones to Natural Philosophy. Given a choice between the likes of you or me, Daniel, versus some available-which is to say idle-retainer, uncle, stooge, or priest who would be inclined to ignore, molest, corrupt, or convert the child en route, such a woman will unfailingly choose the Natural Philosopher; for the worst we will do is bore them.”
“I believe I did just that with little Johann,” said Daniel. “He would respond better, I do believe, to a curriculum centered wholly on Weaponry and its uses. In the absence of weapons, he prefers unarmed combat. I do believe I learned more wrestling-holds from him than he Philosophy from me.”
“That should serve you well when you get to Massachusetts,” said Leibniz gravely, “for the Indians are said to be brave wrestlers all.”
“After he has fenced with Jean Bart on the deck of a warship, to be shut up in a carriage with the likes of me for several days was a miserable fate.”
“Pfui! A slow and excruciating death by lockjaw is the miserable fate of those who play too much with edged weapons,” said Leibniz. “Eliza knows this. You served her well, even if Johann is too young to appreciate it! Tell me, did he really show no curiosity at all?”
“The foolish boy gave me an opening, by discoursing too much of mortars and cannons,” Daniel admitted. “We got into parabolas. I halted the carriage in a field between Munster and Osnabruck and we scattered some peasants by conducting a systematic trial, first with archery, later moving on to firearms.”
“You see? He’ll never forget that! Every time Johann sees a Projectile Weapon-which in this benighted world means every five minutes-he’ll know that they are useless without mathematicks.”
“How far are we from this Pretzsch?”
“You are deceived by the understated style of the place,” said Leibniz. “Behold, we are in Pretzsch, and have been for some minutes.” He slid his window open, laid a hand atop his wig to prevent its ending up under a wheel-rim, and thrust his head out. “The Dower-house is dead ahead.”
“What will you discourse of with the orphan,” Daniel asked, “assuming she does not share Johann’s curiosity about weapons?”
“Whatever she likes,” Leibniz said. “She is after all a Princess, and almost certain to be a Queen one day.” He regarded Daniel skeptically.
“All right,” said Daniel, moving. “I’ll sit up straight.”
THE TRAIN WAS THREE CARRIAGES, a baggage-wain, and several mounted dragoons. The latter had been sent down from Berlin, which was to say they were Brandenburgish/Prussian. Leibniz had met up with these Berliners in Leipzig. This had occurred only an hour after Daniel-who’d only just dropped off Johann, and cashed his Bill of Exchange, at the House of the Golden Mercury-had tracked down Leibniz. The union of these three separate parties was under the command of a Brandenburger noble who was also a captain of dragoons. He was adamant that they must press on across the Elbe and get into Brandenburg territory before nightfall, lest some Saxons give in to the temptation to make things complicated. Daniel found this a little ridiculous, but Leibniz saw wisdom in it. For Caroline might be an impoverished orphan living out in the middle of nowhere, but she was still a Princess, and to have a Princess in one’s custody, voluntary or in-, was to have power. And though Augustus the Strong, Elector of Saxony, was a much better man than his late brother, yet there was no end to his crafty scheming; who knew if he might snatch Caroline up on a pretext and marry her off to some Tsarevich. So the collection of Caroline and her one item of baggage from the Dower-house of Pretzsch was carried through with a brusqueness normally reserved for kidnappings and elopements. This didn’t make it easier for the orphan Princess, but nothing could have done so, and a lingering farewell might have made it harder. By her choice she shared Leibniz’s coffee-brown, flower-painted carriage with him and Daniel. Tears and smiles passed alternately across her face like squalls and sunbeams on a gusty March day. She was thirteen.
