It was plain that something had gone wrong, but Jack Cole was not about to abandon a good rope, and so they hauled in what they could, drawing themselves upstream. Somewhere along the flank of the galjoot, they found a noose in the rope, with a cold pale ankle lodged in it, and out came poor Dick. The anchor cable was knotted to that same noose. While Jack and Bob tried to slap Dick back into life, the mudlarks tried to pull in the anchor. Both failed, for the anchor was as heavy as Dick was dead. Presently, choleric Dutchmen up on the galjoot began to fire blunderbusses into the fog. It was time to leave.

Bob and Jack, who’d been acting as journeyman and apprentice, respectively, to Dick, were left without a Master Rope-Climber to emulate, and with a tendency to have extraordinarily bad dreams. For it was clear to them-if not right away, then eventually-that they had probably caused their own brother’s death by drawing the rope taut, thereby pulling Dick down below the surface of the river. They were out of the mudlark trade for good. John Cole found a replacement for Dick, and (rumor had it) gave him slightly different instructions: take your ankle out of the noose before you cut the anchor cable.

Scarcely a fortnight later, John Cole and his fellows were caught in the longboat in broad daylight. One of their schemes had succeeded, they’d gotten drunk on stolen grog, and slept right through sunrise. The mudlarks were packed off to Newgate.

Certain of them-newcomers to the judicial system, if not to crime-shared their ill-gotten gains with a starving parson, who came to Newgate and met with them in the Gigger. This was a chamber on the lower floor where prisoners could thrust their faces up to an iron grate and be heard, if they shouted loudly enough, by visitors a few inches away. There, the parson set up a sort of impromptu Bible study class, the purpose of which was to get the mudlarks to memorize the 51st Psalm. Or, failing that, at least the first bit:

Have mercie upon me, o God, according to they loving kindenes: according to the multitude of thy compassions put awaie mine iniquities.

Wash me throughly from mine iniquities, and clense me from my sin. For I knowe mine iniquities, amp; my sinne is ever before me.

Against thee, against thee onely have I sinned, amp; done evil in thy sight, that thou maiest be just when thou speakest, and pure when thou judgest.

Behold, I was borne in iniquitie, and in sinne hath my mother conceived me.

Quite a mouthful, that, for mudlarks, but these were more diligent pupils than any Clerke of Oxenford. For on the day that they were marched down the straight and narrow passage to the Old Bailey and brought below the magistrate’s balcony, an open Bible was laid in front of them, and they recited these lines. Which, by the evidentiary standards then prevailing in English courts, proved that they could read. Which proved that they were clergymen. Which rendered them beyond the reach of the criminal courts; for clergymen were, by long-hallowed tradition, subject only to the justice of the ecclesiastical courts. Since these no longer existed, the mudlarks were sent free.

It was a different story for John Cole, the oldest of the group. He had been to Newgate before. He had stood in the holding-pen of the Old Bailey before. And in that yard, below that balcony, in the sight of the very same magistrate, his hand had been clamped in a vise and a red-hot iron in the shape of a T had been plunged into the brawn of his thumb, marking him forever as Thief. Which by the evidentiary standards then prevailing, et cetera, made it most awkward for him to claim that he was a clergyman. He was sentenced, of course, to hang by the neck until dead at Tyburn.

Bob and Jack did not actually see any of this. They heard the narration from those who had mumbled a few words of Psalm 51 and been released and made their way back to the Isle of Dogs. To this point it was nothing they had not heard a hundred times before from friends and casual acquaintances in the neighborhood. But this time there was a new twist at the end of the story: John Cole had asked for the two surviving Shaftoe boys to meet him at the Triple Tree on the morning of his execution.

They went out of curiosity more than anything. Arriving at Tyburn and burrowing their way through an immense crowd by artful shin-kicking, instep-stomping, and groin-elbowing, they found John Cole and the others on a cart beneath the Fateful Nevergreen, elbows tied behind their backs, and nooses pre-knotted around their throats, with long rope-ends trailing behind them. A preacher-the Ordinary of Newgate-was there, urgently trying to make them aware of certain very important technicalities in the Rules of Eternity. But the condemnees, who were so drunk they could barely stand up, were saying all manner of rude and funny things back to him, faster than he could talk back.

Cole, more solemn than the others, explained to Jack and Bob that when the executioner “turned him off,” which was to say, body-checked him off the cart and left him to hang by his neck, Cole would very much appreciate it if Jack could grab his left leg and Bob his right, or the other way round if they preferred, and hang there, pulling him down with their combined weight, so that he’d die faster. In exchange for this service, he told them of a loose board in the floor of a certain shack on the Isle of Dogs beneath which they could find hidden treasure. He laid out the terms of this transaction with admirable coolness, as if he were hanged by the neck until dead every Friday.

They accepted the commission. Jack Ketch was now the man to watch. His office, the gallows, was of admirably simple and spare design: three tall pilings supporting a triangle of heavy beams, each beam long enough that half a dozen men could be hanged from it at once, or more if a bit of crowding could be overlooked.

Jack Ketch’s work, then, consisted of maneuvering the cart below a clear space on one of the beams; selecting a loose rope-end; tossing it over the beam; making it fast with a bit of knot-work; and turning off the bloke at the opposing end of the rope. The cart, now one body lighter, could then be moved again, and the procedure repeated.

John Cole was the eighth of nine men to be hanged on that particular day, which meant that Jack and Bob had the opportunity to watch seven men be hanged before the time came for them to discharge their responsibilities. During the first two or three of these hangings, all they really noticed was the obvious. But after they grew familiar with the general outlines of the rite, they began to notice subtle differences from one hanging to the next. In other words, they started to become connoisseurs of the art, like the ten thousand or so spectators who had gathered around them to watch.

Jack noticed very early that men in good clothes died faster. Watching Jack Ketch shrewdly, he soon saw why: when Jack Ketch was getting ready to turn a well-dressed man off, he would arrange the noose-knot behind the client’s left ear, and leave some slack in the rope, so that he’d fall, and gather speed, for a moment before being brought up short with an audible crack. Whereas men in ragged clothing were given a noose that was loose around the neck (at first, anyway) and very little room to fall.

Now, John Cole-who’d looked a bit of a wretch to begin with, and who’d not grown any snappier, in his appearance and toilette, during the months he’d languished in the Stone Hold of Newgate-was the shabbiest bloke on the cart, and obviously destined for the long slow kicking style of hanging. Which explained why he’d had the foresight to call in the Shaftoe boys. But it did not explain something else.

“See here,” Jack said, elbowing the Ordinary out of the way. He was on the ground below the cart, neck craned to look far up at Jack Ketch, who was slinging John Cole’s neck-rope over the beam with a graceful straight-armed hooking movement. “If you’ve got hidden treasure, why didn’t you give it to him?” And he nodded at Jack Ketch, who was now peering down curiously at Jack Shaftoe through the slits in his hood.
