Henry Arlanc had let it be known that if Daniel ever summoned the will to leave, for an hour or a day, he, Henry Arlanc, could arrange a sedan chair or a carriage. This was nothing more than simple common sense. The streets of London were a good bit more dangerous now than when Daniel had last walked them, and Daniel much more vulnerable. But on a morning like this, with the streets so crowded with well-to-do persons on the move, murderers and footpads were less likely to be encountered than pickpockets. And these would reap only the meagrest of harvests from Daniel.

An odd notion had come in to Daniel’s mind: perhaps the intended victim of the Infernal Device had been, not Daniel or Mr. Threader, but Henry Arlanc.

Now in his years of toil for the Royal Society, Daniel had become a stern judge of odd notions. There were abundant reasons to discard this one straightaway. Its most obvious defect was simply that Daniel had not the faintest idea why anyone would want to blow up the Royal Society’s porter. Moreover, the fog that had descended over Daniel’s mind since the explosion had made him susceptible to hypotheses of an extremely dark and frightening cast, and this seemed like one of those.

But the Natural Philosopher in him had to admit that it was at least theoretically possible. And until it had been ruled out, Daniel liked to preserve, from Arlanc, some independence-he did not wish to get in the habit of relying on the Huguenot every time he stirred from Crane Court-and some privacy. ’Twas neither necessary nor desirable for Arlanc to know everything about his movements around London.

His knees were still recovering from too long spent in bed, but they had become unlimbered by the time he reached the end of Crane Court and flung himself on the mercy of Fleet Street. He turned to the right, therefore moving in the general direction of Charing Cross, and worked his way cautiously upstream, prudently facing on-coming traffic, and with his right hand dabbing at the fronts of houses and shops in case he should be forced to save himself by diving into a door-way. Soon he had left St. Dunstan-in-the-West behind. The Inner and Middle Temple would be to his left, on the opposite side of Fleet, lurking behind a screen of newer buildings. These were largely occupied by pubs and coffee-houses that were continual targets of arch but confusing references, and cruel but murky satire, in newspapers.

Soon he had passed through Temple Bar. The way-now called the Strand-forked into a main channel on the left and an inferior one to the right, creating a long central island with a couple of churches in it. Daniel took the narrower way-really a series of disjoint street-fragments crudely plumbed together-and grew convinced that he was lost. The buildings were held apart by splints of air, too narrow to deserve the name “alley,” that jogged crazily to the right and left, and did not run in straight lines even when they could have. The fire had stopped short of this part of the city, probably because the Rolls and the Temple, with their generous lawns, had acted as fire-breaks. Hooke, in his capacity as City Surveyor, had not been empowered to bring it out of the Dark Ages. These ancient rights-of-way were as sacred, or at least as unassailable, as the precepts of the Common Law. Somewhere among them was an old, therefore low-ceilinged room that had been acquired by a printer, Mr. Christopher Cat, and made into a thing called the Kit-Cat Clubb.

I have spoken to Mr. Cat about you, Roger had let Daniel know, in a note slipped under his door. When you venture out, stop by our Clubb for refreshment. There had been a sketchy map, which Daniel now withdrew from his pocket, and tried to interpret. It was useless. But presently he was able to find his way to the Kit-Cat Clubb simply by following the carriages of Whig M.P.s.

The building had clearly been thrown up in an epoch of English history short on food and building materials, because Daniel, who was of average height, could barely stand up without being bludgeoned by a joist. Accordingly, the paintings that Mr. Cat had commissioned to adorn the walls were all bizarrely wide and short. This ruled out portraits, unless they were portraits of very large groups as seen from tremendous distances. Of these, the largest and most prominently displayed was of the distinguished membership of the Kit-Cat Clubb. Roger was front and center in his best wig, which was captured as a horseshoe-shaped swipe of an overloaded paint-brush.

“LET’S DO SOMETHING about Longitude!”

He was the same Roger in a much older body. Only his teeth looked young, because they were; they could not have been carved more than a few months ago. He had deteriorated in every way save the Mental and the Dental. He made up for it with clothing.

Daniel blew on his chocolate for a few moments, trying to get it to cool without forming a wrinkled hide on the top. He could not hear himself think for all the Whigs in wigs shouting at each other. “The Queen opened Parliament only two hours ago,” he reminded Roger, “or so I’ve been told, and she forgot, entirely, to mention the trifling detail of who would succeed her, after her demise. And you wish to have a chat about Longitude.”

The Marquis of Ravenscar rolled his eyes. “ ’Twas settled ?ons ago. Sophie or Caroline will succeed her-”

“You mean, Sophie or George Louis.”

“Don’t be a fool. Ladies run Europe. The War of the Spanish Succession was all women. In Versailles, Madame de Maintenon. In Madrid, her best friend, the Princesse des Ursins, Camarera Mayor of the Bourbon Court of Spain. She runs the place. Those two on the one side, fought it out against Queen Anne and Sophie on the other.”

“I thought Queen Anne and Sophie hated each other.”

“What’s that got to do with anything?”

“Touche, Roger.”

“Now if you insist on being pedantic, yes, George Louis is next in the queue after Sophie. Do you know what he did with his wife?”

“Something horrible, I heard.”

“Locked her up in a Schlo? for the rest of her life, for bed-swerving.”

“So clearly he has the upper hand, at least-”

“ ’Tis the exception that proves the rule, Daniel. By taking such a measure, he confesses his helplessness to the world. She made him a cuckold. Cuckolds cannot be unmade.”

“Still, she’s locked in a Schlo?, and he isn’t.”

“He is locked up in the Schlo? of his own mind, which, by all accounts, has walls so thick, as to leave very little room within. The leading lady of England will be the Princess of Wales-raised personally by Sophie and by the late lamented, by all accounts dazzling, Queen of Prussia; and tutored by your friend.” This Roger stressed ominously.

“Er, getting back to the actual topic of conversation, don’t you think your time were better spent making sure the Hanoverians actually do succeed to the throne? Longitude can wait.”

Roger waved his hand as if trying for the eleventh time to knock a particular horse-fly out of the air. “God damn it, Daniel do you really think we are so feckless, as not to have thought of that?”

“I beg your pardon.”

“We’re not letting the Pretender in! You were there at his so-called birth-you saw the sleight-of-

hand involving the warming-pan-surely a man of your discrimination was not so easily deceived!”

“To me it looked like a babe’s head coming out of the Queen’s vagina.”

“And you call yourself a man of science!”

“Roger, if you would set aside this quaint notion that countries must be ruled by kings who are the sons of other kings, then it would not matter whether the Pretender entered St. James’s Palace through a vagina, or a warming-pan; either way, to hell with him.”

“Are you suggesting I become a Republican?”

“I’m suggesting you already are one.”

“Hmmph…from there, ’tis only a short step to Puritanism.”
