“Quicksilver,” Daniel said. “Probably discarded from the Royal Society’s laboratories.”

  “Point to it!” Saturn suggested, still staring fixedly at the quicksilver net-work.

  “I beg your pardon?”

  “Point to the Royal Society, and make as if you’re offering up some remark about it.”

  Daniel uncertainly turned round and pointed up the center of Crane Court, though he omitted any feigned remarks. Saturn turned his head to look that way; peered blankly for a few moments; then turned his back on Daniel and shuffled off into Fleet Street.

  Daniel took a few moments to catch up in traffic. The church-bells had struck six P.M. a few minutes ago. Fleet was deadly crowded.

  “I phant’sied you’d have a hackney,” Daniel said, hoping to rein Saturn in by starting a conversation with him. “I did mention that all expenses would be reimbursed…”

  “No need,” Saturn returned, sowing the words back over his shoulder, “the place is all of two hundred paces from here.” He was walking east on Fleet, glancing over his shoulder for openings between riders and coaches and wagons, sometimes trespassing in front of them to claim right-of-way. The general plan seemed to be that they would cross over to the south side.

  “You had intimated it might be near by,” Daniel said, “but I find it startling that a house of that type should lie so near to—to—”

  “To a house of the Royal Society’s type? Not at all, Doc. The streets of London are like bookshelves, you can as leave find unlike houses next to each other as find a picaroon-romance shelved alongside a Bible.”

  “Why did you need for me to point at the Royal Society, just now?”

  “So I might look at it.”

  “I did not know one needed leave to look at it.”

  “That is because you are used to the ways of Natural Philosophers, who are forever peering at whatever pleases them. There is a kind of arrogance in that, you are unawares of. In other walks of life, one does need leave. And ’tis well we are having this talk en route to Hanging-Sword-Alley. For the ken we are going to is most certainly the sort where, Doc, you do need leave.”

  “Why, then, I’ll have eyes only for you, Mr. Hoxton.”

  They had come already to where Water Lane broke away to the right, and ran straight down to the river. Saturn made that turn, as if he meant to ramble down to White Friars Dock. The Lane was a straight and broad cleft separating two jumbled, mazy neighborhoods. On the right, the periphery of the Temple. Typical resident: a practitioner at law. On the left, the parish of St. Bride’s. Typical resident: a woman who’d been arrested for prostitution, thievery, or vagrancy and put to work pounding hemp at Bridewell. In his more peevish moments Daniel phant’sied that the only thing preventing those on the right and those on the left from coming together lewdly in the middle of the Lane, was the continual stream of redolent carts booming down it to eliminate their steaming loads upon Dung Wharf, which could be nosed a short distance ahead.

  Water Lane was lined on both sides by post-Fire buildings, kept up in such a way as to give the casual stroller a frank and fair synopsis of the neighborhoods that spread behind them; which was to say that whenever Daniel walked down this way to the river, he hewed strictly to the right, or Temple, side, trailing a hand along shop-fronts as he went. When he was feeling bold, and was surrounded by well-dressed law-clerks and brawny, honest tradesmen, he would gaze across the way and disapprovingly regard the buildings on the left side.

  There, between a certain pawn-shop and a certain tavern, stretched a narrow gap that reminded him of a missing tooth in a rotten jaw. He had always supposed that it was the result of an error by Robert Hooke, the late City Surveyor, who’d done his work sans flaw in the better neighborhoods, but who, when he got to this district, might possibly have been distracted by the charms of a Bridewell girl. Noting the sorts of people who came and went through that gap, Daniel had sometimes speculated as to what would befall him if he ever went in there, somewhat in the spirit of a seven-year-old boy wondering what would happen if he fell through the hole in an out-house.

  When Saturn had entered Water Lane, he had gravitated to (inevitably) the left side, which caused Daniel to lose his bearings, as he’d never seen it from this perspective. The strolling, snuff-taking lawyers across the way looked doltish.

  After just a few paces Saturn veered round a corner into a narrow, gloomy pass, and Daniel, wanting nothing more than to stay close, hurried after him. Not until they had penetrated ten paces into it did he turn round to look at the bright façades on the other side of Water Lane, far far away, and realize that they had gone into that same Gap he had oft wondered about.

  It were just to describe his movements now as scurrying. He drew abreast of Saturn and tried to emulate his manner of not gazing directly at anything. If this maze of alleys were as horrible as he’d always supposed, why, he did not see its horrors; and considering how briskly they were moving, it hardly seemed as if there would be time for any of them to catch up. He foresaw a long train of stranglers and footpads stretched out in their wake, huffing and puffing and bent over from side-aches.

  “I presume this is some sort of a lay?” said Peter Hoxton.

  “Meaning…a plan…scheme…or trap,” Daniel gasped. “I am as mystified as you are.”

  “Does anyone else know where we are going, and when?” Saturn tried.

  “I let the name of the place, and the time of the meeting, be known.”

  “Then it’s a lay.” Saturn darted sideways and punched his way through a door without knocking. Daniel, after a clutching, febrile moment of being by himself in the center of Hanging-Sword-Alley, scrambled after him, and did not leave off from scrambling until he was seated next to Peter Hoxton before the hearth of a house.

  Saturn spooned coal onto the evidence of a late fire. The room was already stuffy; these were the last chairs anyone wanted.

  “This is really not so very dreadful after all,” Daniel ventured.

  Saturn rummaged up a bellows, got its two handles in his hands, and held it up for a mechanical inspection. A brisk squeeze slapped lanky black locks away from his face. He aimed it at the pile of coal and began crushing the handles back and forth as if the bellows were a flying-machine, and he trying to raise himself off the floor.

  Following Saturn’s warnings, Daniel had religiously avoided looking at anything. But the close, and now smoky, air of this parlour was leavened by female voices. He could not stop himself turning to look at an outburst of feminine laughter from the far end of the room. He got an impression of rather a lot of mismatched and broken-down furniture arranged in no particular way, but swept back and forth across the room by ebbing and flowing tides of visitors. There might have been a score of persons in the room, about evenly divided between the sexes, and clumped together in twos, threes, and fours. At the far end was a large window looking out onto a bright outdoor space, perhaps Salisbury Square in the heart of St. Bride’s. Daniel could not tell, because the windows were screened with curtains, made of rather good lace, but too large for these windows, and tarred brown as naval hemp by pipe-smoke. They were, he realized with a mild thrill, curtains that had been stolen—probably snatched right from someone’s open window in broad daylight. Silhouetted against that ochre scrim were three women, two gaunt and young, the other plump and a bit older, and smoking a clay-pipe.

  He forced himself to turn his attention back to Saturn. But as he did so he scanned the room and got an impression of many different kinds of people: a gentleman who would not have looked out of place promenading round St. James’s Square, as well as several who belonged more to Hockley-in-the-

  Hole.

  By his exertions Saturn had evoked light, but no perceptible heat, from the rubble of coals and ashes on the hearth. That was enough—no heat was wanted. It seemed he’d only wanted something to occupy his nervous hands.

  “A lot of females!” Daniel remarked.

  “We call them women,”
Saturn snapped. “I hope you haven’t been peering about like some damned Natural Philosopher at a bug collection.”

  “We call them insects,” Daniel shot back. This elicited a gentlemanly nod from Saturn.

  “Without peering,” Daniel continued, “I can see well enough that, though it’s untidy, it’s far from loathsome.”

  “To a point, criminals love order even more than Judges,” Saturn said.

  At that moment, a boy entered the room, breathing hard, and scanned the faces. He picked out Saturn instantly, and moved toward him with a joyous expression, reaching significantly into his pocket; but Peter Hoxton must have given him a glare or a gesture, because suddenly his face fell and he spun away on his heel.

  “A boy who snatches your watch in the street, and runs off with it, does not do so out of a perverse longing to cause you grief. He is moved by a reasonable expectation of profit. Where you see sheep being sheared, you may assume there are spinning-wheels nearby; where you have your pocket picked, you know that there is a house such as this one within sprinting-distance.”

  “In its ambience ’tis rather like a coffee-house.”

  “Aye. But mind, the sort who’re disposed to abhor such kens as this would say its hellishness inheres in its very congeniality.”

  “I must admit, it smells less of coffee than of the cheap perfume of geneber.”

  “Gin, we call it in places like this. My downfall,” Saturn explained laconically, peering over his shoulder at the boy, who was now in negotiations with a fat, solitary man at a corner table. Saturn went on to give the room a thorough scan.

  “You dishonor your own rules! What are you looking at?”

  “I am reminding myself of the exits. If this turns out to be a lay, I shall not bother excusing myself.”

  “Did you perchance see our buyer?” Daniel inquired.

  “Save my fellow horologist in the corner there, and this gager next to us, who is trying to wash away his pox with gin and mercury, everyone here has come in groups,” Saturn said, “and I told the buyer that he must come alone.”

  “Gager is what you call an elderly man.”

  “Yes.”

  Daniel hazarded a look at said gager, who was curled up on the floor in the corner by the hearth, no more than a sword-length from them—for the room was small, the tables close, and the separation between groups was preserved only through a kind of etiquette. The gager looked like a whorl of blankets and worn-out clothes, with pale hands and a face projecting from one end. Resting on the hearth-stones directly before him were a clay bottle of Dutch geneber and a thumb-sized flask of mercury. This was the first clue that he was syphilitic, for mercury was the only known remedy for that disease. But confirmation could be had by looking at his face, which was disfigured by lumpy tumors, called gummas, rimming his mouth and his eyes.

  “Every snatch of conversation you overhear in this room shall be riddled with such flash cant as ‘gager,’ ‘lay,’ et cetera, for here, as in the legal and medical professions, the more impenetrable a man’s speech, the higher the esteem in which he is held. Nothing would be more injurious to our reputation in this house, than for us to speak intelligibly. Yet we may have to wait for a long time. And I fear I may fall into drinking gin, and end up like yon gager. So, let us have an unintelligible conversation about our religion.”

  “I beg your pardon?”

  “Remember, Doc, you are my Father Confessor, I your disciple, and your portion of our bargain is that you shall help me draw nigher to Truths Æternal through the sacrament of Technology. This—” and he scanned the room lightly, without letting his eye catch on anything, “is not what I signed on for. We were to be in Clerkenwell, building things.”

  “And we shall be,” Daniel assured him, “once the masons, carpenters, and plasterers have finished their work round the old Temple there.”

  “That should not be long. I’ve never seen stones piled up in such haste,” Saturn said. “What is it you mean to make there, then?”

  “Read the newspapers,” Daniel returned.

  “What’s that s’posed to mean?”

  “What’s the matter, you’re the one who wanted to speak in cyphers.”

  “I do read the newspapers,” said Saturn, wounded.

  “Have you attended to what goes on in Parliament?”

  “A lot of screeching and howling as to whether our next King’s son* ought to be given a hero’s welcome in the House of Lords, or barred from the Realm.”

  Daniel chuckled. “You must be a Whig, to refer so confidently to George Louis as our next King.”

  “What do I look like to you?” said Saturn, suddenly lowering his voice, and looking about uneasily.

  “A Jacobite Tory, dyed in the wool!”

  Daniel’s chuckling at his own jest was, for a few moments, the only sound in the room. Then:

  “There’ll be no such talk in this house!”

  The speaker was a short, stout Welshman with a large jaw. He was wrapped in a bulky and bulging black cloak, as if he’d just come in from outside, and was making a sweep through the parlour on his way back to the kitchen. A brace of empty gin-bottles dangled by their necks between the fingers of his right hand, and a full one was gripped in his left. Daniel assumed the fellow was being wry, and chuckled some more; but the Welshman very deliberately swiveled his head around and gave Daniel a glare that shut him up. Most of the people in the room were now looking their way.

  “Your usual, Saturn?” the Welshman said, though he continued to stare fixedly at Daniel.

  “Have her bring us coffee, Angus. Gin disagrees with me these days, and as you have perceived, my friend has already drunk one bottle too many.”

  Angus turned around and stalked out of the room.

  “I am sorry!” Daniel exclaimed. Until moments ago he had felt strangely at home here. Now, he felt more agitated than he had out in the alley.

  The wretch on the floor went into a little fit of shuddering, and tried to jerk his unresponsive limbs into a more comfortable lie.

  “I assumed—” Daniel began.

  “That the words you were using were as alien to this place as the Calculus.”

  “Why should the proprietor—I assume that’s what he was—care if I make such a jest—?”

  “Because if word gets round that Angus’s ken is a haunt of such persons—”

  “Meaning—?”

  “Meaning, persons who have secretly vowed that the Hanover shall not be our next King,” Saturn croaked, so quietly that Daniel was forced to read his lips, “and that the Changeling* shall be, why, it shall become self-fulfilling, shall it not? Then such persons—who are always in want of a place to convene, and conspire—will begin to come here.”

  “What does it matter!?” Daniel whispered furiously. “The place is filled with criminals to begin with!”

  “And that is how Angus likes it, for he is a past master among thief-takers,” Saturn said, his patience visibly dwindling. “He knows how it all works with the Watch, the Constables, and the Magistrates. But if the supporters of the Changeling begin to convene here, why, everything’s topsy-turvy, isn’t it, now the house is a heaven for Treason as well as Larceny, and he’s got the Queen’s Messengers to contend with.”

  “I hardly phant’sy the Queen’s Messengers would ever venture into a place like this!” Even Daniel had the wit to mouth the name, rather than speaking it aloud.

  “Be assured they would, if treason were afoot here! And Angus would be half-hanged, drawn, and quartered at the Treble Tree, ’long with some gaggle of poxy Jacobite viscounts. No decent end for a simple thief-taker, that.”

  “You called him that before.”

  “Called him what?”

  “A thief-taker.”

  “Naturally.”

  “But I thought a thief-taker was one who brought thieves to justice, to collect a reward from the Queen. Not a—” But Daniel stopped there, as Peter Hoxton had got a look on his phizz that verged on nausea,
and was shaking his head convulsively.

  “I see you’ve been sending my coal right up the fucking Chimney!” Angus proclaimed, stalking toward them. He had divested himself of the cloak and the gin-bottles and was now being followed, at a prudent distance, by a Bridewellish-looking girl with a mug of coffee in each hand.

  “Rather, providing you with the service of keeping the fire going,” Saturn answered calmly, “at no charge, by the way.”

  “I didn’t want it going to begin with!” Angus returned. “ ’Twas that lappy-cull who mewled and pleaded for a bit of warmth! Now you’ve gone and got it going again! There’ll be a charge for that!”

  “Of course there will be,” Saturn said.

  The coffee was served, and money changed hands, in the form of copper tokens, minutely examined by Angus.

  “Now why do you say I should attend to the doings of Parliament?” Saturn asked, as they were beginning to sip their coffee. “What connexion could I possibly draw between the situation of the Duke of Cambridge* and your hole in the ground in Clerkenwell?”

  “None whatever. Save that Parliament’s more loud and obvious doings may be used as a sort of screen or blind to cover arcane, subtile machinations that might reward your attention.”

  “This is worse than being given no information at all,” Saturn grumbled.

  A man entered solus, and began to look round the place. Daniel knew immediately it was their buyer. But rather than jumping to make their presence known, he settled deeper into his chair so that he could spend a few moments inspecting the newcomer. In silhouette against the glowing screen of curtains, he could easily be confused with an actual gentleman, for he wore a wig, clamped down by a hat with a vast brim folded upwards in the style then mandatory. A sword dangled from one hip. But when he stood, he crouched, and when he walked, he scuttled, and when he noticed things, he flinched. And when this man came over to the hearth, and accepted a chair pulled up by the uncharacteristically hospitable Peter Hoxton, Daniel perceived that his wig was stinking horsehair, his hat was too small, and his sword was more danger to himself, in its sheath, than it would’ve been to others, out of it. He nearly tripped over it twice, because every time he whacked it off a chair- or table-leg it jumped back between his ankles. He put Daniel in mind of a clown at St. Bartholomew’s Fair, got up to mock a gentleman. Yet the mere fact that he was trying so hard earned him a sort of dignity, and probably counted for something in a house of this type.
