Jack had been playing the recluse since he had been condemned. In the first days, crowds had gathered in Holborn from time to time, apparently drawn by rumors that Jack Shaftoe was going to get out of bed and stand in his window to be viewed, like a King taking the air in St. James’s. All of them had been driven away, disappointed, by constables. But tonight was a special occasion, for how many times in his life would Jack be half-hanged, drawn, and quartered? Jack busied himself for a minute or two, lighting tapers. For sources of illumination were another luxury that was famously in short supply at Newgate, and those sycophants who lacked the Yellow Boys (that is to say, Guineas) to buy Jack bottles of Oporto might at least scratch together thrums (that is to say, three pence) to buy him a taper, so that he might take good aim at his chamber-pot later. He had not been burning many of these, but at this point there was little reason to hoard them, and so he went round and set every one of them alight. The room immediately filled with lambent smoke, and the fragrance of rancid tallow, which took him right back to his boyhood on the Isle of Dogs. There was a small ironbound hatch in one of his windows, which might be opened to admit air. He did so now, to spill out the smoke, and was spotted by the crowd down in Holborn, who phant’sied that Jack Shaftoe had nothing better to do on this, his last night, than to banter with them. That damned bell started up, quieting a surge of excitement from the crowd, and the Bell-Man roared out his stanza.

Jack was ready for him. He put his face to the open grate and shouted back,

O tedious Man, who with thy Bell

Dost ring me down the road to Hell,

Tomorrow eve, at half past seven,

I’ll hock a spit on you from Heaven.

For if, as preachers say, the afterlife

Smells sweet, sounds pleasant, is free of strife,

And is, in sum, a Kingdom of Felicity,

It must be any place that does not harbor Thee.

The performance was extremely well-received by all hearers save the Bell-Man himself, who slinked away in the direction of St. Sepulchre, stepping a bit lively as turds and expired vegetables began to pelt him in the back.

Now that he’d been sent away in disgrace, the only people remaining were members in good standing of the Mobility, a.k.a. the Mobb, a class of people divided by their tendency to rape, murder, and steal from one another, but united in their admiration for Jack. They were expecting something from him, without a doubt. A few groups were trying to sing songs to him, in different keys and meters, but no one tune had taken hold yet. Jack-who must be nothing more, to them, than a silhouette against a smoky candle-lit chamber, half-obscured by the reticule of massive iron bars-waved his arms a bit to quiet them down, then put his face to the grate again, and shouted:

“The curfew-bell has sounded, and the gentleman from St. Sepulchre has given me his stanzas, and I am retiring! As should you all! For we have a long and busy day ahead of us tomorrow! I have an appointment at Tyburn in the morning, to which you are all invited! And then another at the College of Physicians in the afternoon. For even though my body is to be quartered, my head is expected to come through the ceremony more or less intact, and those Natural Philosophers around the corner there-straight up Newgate Street, take a right on Warwick Lane just across from Grey Fryars, there, then down to the first entry on your right, the large building with the golden pill on the top-they’re going to cut open my skull tomorrow and peer inside, to see if they can ascertain why I am such a bad fellow.”

He was answered by a general scream of rage, so disturbing to the peace and quiet of his gentlemanly abode, that he shut the hatch immediately. And a good thing, too, for moments later, a hailstorm struck. The noise of small objects assaulting the windowpanes grew until it was louder than the screaming was. Jack approached the window again, out of curiosity, and saw that farthings and pennies, and even a few shillings, were piling up on the stone windowsill outside, so thick that they were forming up into drifts. The people were throwing money at him, money to pay for a Christian burial, to keep him out of the hands of the College of Physicians. And the ones who couldn’t afford to fling coins, were charging up Newgate Street in a torchlight stampede, looking for that first right turn that Jack just told them about. It promised to be a long and eventful night at the College of Physicians; but at least Jack Shaftoe would get some privacy, and some sleep.

“MR. THREADER,” the butler announced.

Daniel looked up, and turned around.

Mr. Threader stood in the laboratory doorway, hat in hand, decidedly cringing, looking about the room as if expecting Sir Isaac Newton to spring out from behind a glowing furnace and turn him into a newt.

“He is not here,” Daniel said gently. “He is at his niece’s house.”

“Recuperating-or so ’tis rumored-from an attaque of some sort-?” Mr. Threader, emboldened, stepped over the threshold. The butler closed the door behind him and walked away.

“We shall help him recuperate, you and I. Please, please, come in!” Daniel beckoned with one, then both hands. Mr. Threader obeyed with extreme reluctance. He was not accustomed to Alchemical laboratories. The glowing furnaces, the smells, the open flames, the jars and retorts with their cryptic labels, were all vaguely threatening to him. Seeing as much, Daniel felt, for a moment, what a second-rate Alchemist must feel when a gullible person ventures into his shop: a smug self-satisfaction in the bamboozlement and bewilderment of one’s fellow-man, and a perverse urge to milk the wretch for all he is worth.

But alas, he had other errands, and must needs put Mr. Threader at ease.

“It must all seem quite foreign to you. I was fortunate: I was chumming with Isaac during the years that he turned our domicile into one great smoking Lab. So, all the stuff you see around you here was moved in to our house one bit at a time, and I could ask Isaac what it was, and how to use it.” Daniel laughed. “I am more at home here than I should care to admit!”

Mr. Threader permitted himself a dry chuckle. “I must say that you look quite at home here, which is quite amusing after all of the unkind remarks you have made about Alchemy.”

Daniel wondered what Mr. Threader would make of it if Daniel were to let him know that tomorrow he, Daniel, might be the most eminent Alchemist since King Solomon went in to the East. But he shook it off as being too uncanny to speak of just now.

“Is Sir Isaac expected to be in any condition to attend the Trial?”

“He would not miss it for anything.”

“It is good to know his condition improves.”

Daniel said nothing. Isaac’s condition was not improving; he suspected that the gaol-fever was creating a lesion on Isaac’s heart. As a boy Isaac had tried to make perpetual motion machines, seeing in them a model of the heart. But Isaac’s heart, Daniel suspected, was about to give out. Men had not been able to fashion perpetual motion machines because men were mechanics who only knew how to work with inert matter. Hearts pumped longer than any machine could, because the matter of which they were made-or so Alchemists supposed-was suffused with the vegetative spirit.

“Let’s make some money!” Daniel said. “Did you bring the molds?”

What Daniel had mentioned was so perilous that Mr. Threader, by way of an answer, could only flinch. “Do you have a bit of gold?” he returned.

Daniel flourished his right hand, then pulled off the gold ring and tossed it without ceremony into a small crucible. Picking this up with a pair of tongs, he made to thrust it into a small, keening, and radiating furnace. “Is it fine gold?” Mr. Threader wanted to know.
