So much for mail from persons he actually knew. He worked his way deeper into the basket. Metallic clanking and scraping noises issued from its depths as he stirred through it. There were a few letters from Londoners who, starting as of a month ago, had become his fellows on the Court of Directors of the Proprietors of the Engine for Raising Water by Fire. There were two from chaps whose names he did not recognize at all, but who had orderly minds-or so he guessed from their handwriting. These two were the only letters he actually bothered to open and read, simply because they were the only ones whose contents were not wholly predictable. As it turned out, both were from men who had come up with inventions for determining longitude, and sought Daniel’s help in bringing their ideas before the Royal Society. Daniel threw them away.

There were no letters from his wife, or from little Godfrey, which was in no way surprising, given the season of the year and the rough weather. Groping to the very bottom of the basket, he scraped his hand on something jagged, and jerked back. He was not too old to die of tetanus. His fingers emerged sooty, rather than bloody. Pulling all the mail out of the basket and then tilting it towards the window he observed several twisted and blackened shreds of wood and of metal in the bottom. The largest bit was a miniature cask, no more than gallon-sized, such as might be used to transport distilled spirits. One end of it was intact-badly damaged to be sure, but still recognizable as having once been a keg. The staves were bound together by an iron band at the end, and spread out, like lines of longitude from the pole, until they reached the equator. But none of them continued very far into the opposite hemisphere. Some were snapped off clean, some bent outwards, some smashed into splintery brooms. That end of the keg, and its metal band, were gone entirely, though they might be accounted for by some of the loose fragments in the bottom of the basket. Other things were in there, too: gears, springs, levers of wrought brass.

Part of Daniel wanted to overturn this basket on a well-illuminated table and piece the device back together. But instead he buried it again under his unread mail. He had spent a fortnight immobilized by melancholy, and tormented by unreasonable fears. Today his humours had gone back into balance. The Daniel Waterhouse who had cowered in that bed for two weeks was a different chap from the one who was standing by the door, dressed and periwigged. But they could easily change places if he dwelled too long on the dark relics in that basket. They had grown cold, waiting for his attention; let them grow colder still.

THE ROYAL SOCIETY’S HEADQUARTERS comprised two separate houses and a tiny courtyard separating them. During the fund-raising effort, some had gone so far as to style it a “compound.” One of the houses was the northern terminus of Crane Court. Above its ground floor it had two addtional full storeys, plus a garret in the roof space. This garret, which was where Daniel had been lodged, had two small dormer windows facing the Crane Court side, which would have afforded a clear view all the way down to Fleet Street, and even to the Thames, had they not been partially blocked by a low parapet-wall that had been added to the front of the house to make it seem a few feet higher than it really was. So from his bed, Daniel’s view had been of a sort of lead-lined ditch formed where the steeply sloping roof plunged down to die in the base of the parapet: a bathing-place for birds when it rained, and a raceway for rodents in all weathers. For a few hours in the afternoon the sun would traverse the rectangle of sky that showed above the parapet, if the weather happened to be clear. If Daniel stood up and approached the window he could see over the lip of the parapet, where moss, soot, and birdshit vied for hegemony, down into Crane Court, and scan the jumble of rooftops all around. A view of the dome of St. Paul’s was denied him unless he opened the window, thrust his head out, and craned it to the left. Then it was startlingly close. Yet it seemed inapproachable because of the wide crevasse of Fleet Ditch, which broke the city in twain half-way between. If he turned one hundred eighty degrees and looked west, he was confronted by a church that was much closer, and infinitely older: the Rolls Chapel, which appeared to be sinking or collapsing into a spacious church-yard just across Fetter Lane. This medieval pile, which had been used by Chancery as a records dump for many centuries, had turned black with coal-smoke during Daniel’s lifetime. A bow-shot to the south of it, fronting on Fleet Street, was the Church of St. Dunstan-in-the-

West, a Wren production, duly turning black.

Much less strenuous for an old stiff-necked man was simply to gaze southward down the length of Crane Court and hope to glimpse a bit of open water between the buildings that filled most of the space between Fleet Street and the river. This view, every time he spied it, made Daniel feel as if he had, by some error in navigation, been taken to some city as strange as Manila or Isfahan. For the London in which he had grown up had been a congeries of estates, parks, and compounds, thrown up over centuries by builders who shared a common dream of what a bit of English landscape ought to look like: it should be a generous expanse of open ground with a house planted in it. Or, in a pinch, a house and wall built around the perimeter of a not-so-generous patch of ground. At any rate, there had been, in Daniel’s London, views of sky and of water, and little parks and farmlets scattered everywhere, not by royal decree but by some sort of mute, subliminal consensus. In particular, the stretch of riverbank Daniel could see from this garret had been a chain of estates, great houses, palaces, courts, temples, and churches put up by whatever powerful knights or monks had got there first and defended them longest. During Daniel’s lifetime, every one of these, with the exceptions of the Temple (directly across from the outlet of Crane Court) and Somerset House (far off to his right, towards where Whitehall Palace had stood, before it had burned down), had been demolished. Some had been fuel for the Fire and others had fallen victim to the hardly less destructive energies of Real Estate Developers. Which was to say that with the exception of the large open green of the Temple, every inch of that ground now seemed to be covered by Street or Building.

Turning his back on the window and opening his bedchamber door brought him back to London straightaway-not the London of average Londoners, but the circa-1660, Natural-Philosophic London of John Wilkins and Robert Hooke. For the remainder of the attic was packed to the rafters with material that Daniel recognized and identified under the broad heading of, Science Crapp. All had been brought over from the Royal Society’s creche at Gresham’s College.

Gresham’s College had been precisely the sort of structure that had no place in modern-day London: a compound, rather than a house, built around a court that was spacious enough to house hundreds of Londoners if razed and jammed with town-houses. Gresham’s had been Tudor wattle-and-daub, a style that encouraged builders to make it up as they went along, and generally suffered them to get away with it. Whatever it might have looked like in Sir Thomas Gresham’s mind’s eye, when he had come back from Antwerp, famous from mending Gloriana’s coinage, and rich from speculating in it, by the time Daniel had got there it seemed to have been made not by human architects but by wasps.

At any rate it had been huge: ten times the size of the two Crane Court houses combined. They had not had the whole thing to themselves, but they’d had a lot of it.

Also they’d had Hooke and Wren, who’d built London up from cinders. If there was a cellar, closet, attic, or shed anywhere in London that was sitting vacant, Wren would know of it, and Hooke would have the temerity to use it for something.
