FORCED TO BECOME a criminal investigator, Isaac Newton committed himself to doing the job well. In August and September 1696, he devoted as many as half his working days to the case of the missing dies. Once he got through the initial round of interrogations, he paused to consider just how a proper investigation should be run.
He soon established his basic strategy. He knew that coining was of necessity an organized crime. And if he could not work that out from first principles, Cooke's and White's testimony taught him the facts of the counterfeiter's life: it was impossible to coin on any scale without confederates—which meant that there were always at least three or four people who could bear witness against each other, even before a single dud guinea reached the street.
That was where the greater vulnerability lay, of course; the problem of making an illegal sale has plagued aspiring crime lords throughout recorded history. Then as now, master counterfeiters did everything they could to avoid direct contact with the street-level trade, selling off coins in large lots to buyers who would then recruit others to pass the money into daily use. But there was still a chain of contact that could trace a single false piece back up the line. Worse, given the ratio of risk to reward at the bottom of the food chain, street-level traders in bad coin had every reason to talk when caught. In theory, and sometimes in practice, even a trivial quantity of bad money could doom someone to a coiner's death. And always, while captured suspects waited to see what clemency might be theirs, the evils of Newgate remained an effective way to loosen tongues.
All this dictated Newton's approach. To break the threat of counterfeiting, he would need to capture and convict major players. To do so, he had to have witnesses and physical evidence that would link those players directly to the crime, to the making and disseminating of coin—a strong enough link so that even the most soft-hearted jury would convict. To find that evidence and to connect it to the men he wanted, he needed to roll up the networks no counterfeiter could do without, starting at the bottom, trading precisely measured grains of mercy for the knowledge he needed. Like any street cop in history—and unlike any other fellow of the Royal Society or Cambridge don—he would have to wade hip-deep into London's underworld.
He began to do so no later than September 1696. While pursuing the implications of Cooke's and White's confessions, he recruited his first agents to develop other cases, men he sent out in an unprecedented sweep of undercover operations. On September 11, 1696, his accounts record five pounds "paid Humphrey Hall to buy him a suit to qualify him for conversing with a gang of coiners of note." That was some suit: five pounds was a month's pay for a clerk at the Mint. Newton was clearly aiming high here, sending Hall to mix with a flash crew, notable crooks who dressed to match their success.
Over the next several months, Newton ranged further in the hunt. To solve any problems of jurisdiction, he got himself appointed a justice of the peace for seven counties surrounding London's metropolitan sprawl. Thus armed, he dispatched men in pursuit of coining rings wherever the evidence led. An agent who lived in the London suburb of Islington traveled back to Newton's recent home, Cambridgeshire. There, posing as a coiner on the lam from the capital, he wormed his way into a fully equipped coining operation, complete with furnace, flattening mill, and a version of the Mint's "secret" milling machines.
These investigations were expensive. The brothers Benjamin and Charles Maris, who traveled through Worcestershire and Shropshire in late 1696, billed Newton £44 2s. for wages, expenses, and tongue looseners. Bodenham Rewse, also known as Benjamin Reuss, listed in court documents as an embroiderer living in Bow Street, actually made his living as a thief-taker. Between 1693 and 1695, he and a partner brought charges against twenty-two prostitutes and more than a dozen owners of brothels. But his career really took off when he entered the Warden's service. Newton clearly trusted him, giving him several arrest warrants to execute, and then paying him £34 to pursue coiners operating to the west of the city. Both men benefited. Newton was able to prosecute several coiners based on his man's investigations, and by 1701 Rewse had picked up enough spare change in bounties and rewards to be able to buy the post of head turnkey at Newgate—thus reaching the top of the system of more or less legal plunder that could turn jailers into rich men. In all, when Newton accounted for his out-of-pocket expenses incurred in the pursuit of coiners from 1696 to 1699, he came up with a total of £626 5s. 9d., or well over a year of his own salary as Warden. That was more than enough to support a serious private force, answering only to Newton, to be aimed at whomever he chose.
Inevitably, some agents turned bad. By 1697, both the Maris brothers ended up on the wrong side of the locks at Newgate, one for smuggling, the other for coining. Others the Warden employed were worse. Hopton Haynes, usually almost worship-fully loyal to his patron, acknowledged that the agents Newton recruited "lay under violent suspicion of being scandalously mercenary." There was Samuel Wilson, who confessed to Newton that he had sold "a pair of Dyes for making mill'd Shilings" for five pounds. Newton gave his informant a Warden's warrant to arrest the buyer—and Wilson seized on the document as a gift, "as good a Sham as could be to get money." He used the warrant to blackmail victims for a year and a half before he was betrayed in turn.
Then there was the terrifying John Gibbons, porter of Whitehall and already one of William Chaloner's more valuable contacts. The authorities in London, Newton among them, used Gibbons for years as a thief-taker, charged with performing what would become essential police functions: running informers, searching suspect premises, executing arrest warrants. Gibbons used these powers to operate a lucrative side business. He did arrest those who forced him into such unprofitable inconvenience, and he pocketed whatever bounties he could claim, but his protection racket earned him much more.
Newton eventually recognized that his man had gone too far to the bad. He turned his attention to the problem in the spring of 1698. Witness after witness told him how thoroughly Gibbons had come to terrorize the coining world. One informant told Newton that paying Gibbons "a certain pension quarterly and yearly" was a fact of life, part of any London coiner's overhead. Gibbons's onetime lover Mary Townsend testified that he had been running his protection scheme for at least six years, while a captured coiner named Edward Ivy (aka Ivey) confirmed that the racket was still going strong: "Gibbons corresponds with a great many Clippers and Coyners and used to receive severall summs of money from them as contribution for coniving at ym. [them] and was wont to Solicit for any of ym. when they were in restraint." Gibbons's standard price seemed to be fifty pounds, though he would occasionally suggest alternatives, and he did not always, or only, demand cash. Elizabeth Bond told Newton that she had seen Gibbons lead a Mrs. Jackson into "a little adjouning room with a Bedd" and that when they emerged, "Mrs. Jackson trembled with her hands and Jawes and lookt pale." Jackson could merely have been terrified, but the pointed mention of the bed suggests something more, and the hint of sexual extortion runs through the witnesses' accounts. At the height of his power, Gibbons put the bite on most if not all coiners who came to the attention of the authorities, among them William Chaloner, who, Gibbons boasted, was "sought after for coyning of Gineas and pistols" but was "safe enough for he had secured him."
Newton neither participated in nor tolerated his agents' excesses, but, then as now, corruption was an inevitable byproduct of policing any highly profitable illegal business. The fact that he had to use thieves, extortionists, and coiners themselves to capture those he wanted more did not much matter to him. Partly the problem was self-correcting: the worst of his men tended to overreach to the point where he could deal with them as needed—and in the meantime his thugs got results. By early 1697, Newton's network of informers, undercover agents, and street muscle had turned him into the most effective criminal investigator London had yet seen.
Newton was willing to stick his own oar in too, as needed. In October 1699, he submitted another bill to the Treasury. He asked for £120 to cover "various small expenses in coach-hire & at Taverns & Prisons & other places." He spent that sum on personal forays through London, buying drinks for informers, sweetening the deal for accomplices—all in all, diving as deep as needed into the muck of the capital's criminal landscape.
He did not shy from the more brutal side of the job either. He personally examined those he and his men caught—showing up in the cells at Newgate if necessary, hauling informants into the Mint's narrow, private chambers at the Tower if he could. Typically, Newton would ask the questions and take notes while a clerk wrote a summary of the deponents' confessions, to be signed once the ordeal ended. Most of those documents have disappeared, perhaps suspiciously. John Conduitt, Newton's nephew by marriage and his successor at the Mint, reported that he helped Newton burn "boxefulls of informations in his own handwriting."
Conduitt chose not to explain why Newton wanted to destroy the papers, but one inference is that Newton enjoyed the role of inquisitor too much. In this view, Newton proved willing, perhaps eager, to terrorize his captives in pursuit of the necessary confessions and betrayals with a viciousness that even that strong-stomached time would tolerate. Formally, torture had not been used in England as an investigative tool for about half a century before Newton came to the Mint. Elizabeth I had faced repeated rebellion, often animated by Catholic ambitions on her Protestant throne—and she was England's most prolific torturing monarch, authorizing fifty-three of the eighty-one warrants on record. The rack was the most common tool used to extract confessions, but occasionally Elizabethan inquisitors grew more inventive. On November 17, 1577, Thomas Sherwood was consigned to a dungeon overrun with rats, and on January 10, 1591, four torture commissioners were ordered to confine the dangerous priest George Beesley and a co-conspirator in the tiny cell known as Little Ease. There, Beesley could not sit or stand or move at all.
The last case of legal torture in England came in the spring of 1641, after a riot of about five hundred people at the Archbishop of Canterbury's palace at Lambeth. One man was identified and arrested: John Archer, a young glover or glover's apprentice. He had made one disastrous mistake. In the midst of the tumult, he took up a drum with which to urge the crowd forward. That turned a Monday night's rough party into the crime of sedition, for "marching to the beat of drum was held to be a levying of war against the king."
Archer did not name any ringleaders, so on May 21, King Charles I issued the last English torture warrant. It ordered the lieutenant of the Tower first to show Archer the rack. He looked; he remained mute, refusing to name names. That silence invoked the second part of the warrant: his interrogators were "to cause him to be racked as in their discretions shall be thought fit." At this point, the Tower's men had to place Archer on his back beneath the frame of the rack with his wrists and ankles bound to two rollers. Men at the levers attached to each roller heaved on order. Archer's body rose until it was level with the frame. With the next pull, the rack strained on his limbs, starting his bones from their sockets, threatening his fingers and toes, hands and feet. He may have been stoic beyond imagining, or he may have been just one more rowdy man who got mixed up in a crowd and truly had no one to betray. Either way, Archer did not speak. In the end, his tormentors gave up. He was hanged the next day.
But for all the pain and retributive satisfaction produced by torture—James I famously blessed the torturers who worked on the assassin Guy Fawkes, saying, "God speed your good work"—officially sanctioned torment fell out of favor, at least as a tool with which to acquire evidence fit for a criminal trial. England's use of juries helped dampen enthusiasm for the practice: juries could convict on any evidence they chose, and thus did not need a confession wrung out of an offender's howl of pain. There was even appreciation of the fact that confessions, or any evidence gained under torture, might not be entirely reliable.
But while official torture fell out of favor, interrogators still knew how to put the boot in as needed. Isaac Newton had plenty of ways to extract the information he wanted from reluctant prisoners, and he made use of all of them. Most of them were within the customary bounds of police detection: trading in fear, not pain. He offered brief reprieves for information; he coerced husbands with threats and promised rewards to wives and lovers. But there is one—and only one—reference to his use of more brutal methods in the records he did not burn. In March 1698, Newton received a letter from Newgate written by Thomas Carter, one of Chaloner's closest associates. The letter was one of a flurry of messages Carter had sent to confirm that he was eager to testify against his former co-conspirator, but this one had a postscript. "I shall have Irons put on me tomorrow," he wrote, "if yo[ur] Worship not order to the contrary." In other words: Don't hurt me! Please. I'll talk. I'm ready.
An ugly moment. Shackling in irons is not the same as racking someone, but the capacity to inflict terrifying pain was there. Some historians have simply condemned Newton, viewing what they see as the bloody ruthlessness of his pursuit of counterfeiters as evidence of a damaged mind, a heartless man. Frank Manuel, one of the most influential of Newton's biographers, argued that what he saw as Newton's pleasure in the chase and ultimate execution of coiners was a kind of catharsis of the anger and loss that had driven him mad in 1693. "There was an inexhaustible font of rage in the man," Manuel writes, "but he appears to have found some release from its burden in these tirades in the tower." He added, "At the Mint, [Newton] could hurt and kill without doing damage to his puritan conscience. The blood of coiners and clippers nourished him."
This is almost certainly nonsense. There is no record of Newton's gloating over his victims, or of his being present during any attempt to use physical coercion to extract information. Rather, he was a familiar figure, just doing his job, a bureaucrat using the means that were generally available at the time. Everyone involved in the criminal justice system had recourse to the ordinary miseries of imprisonment, privation, and then, as needed, the back room and all its terrors. The threat alone was probably good enough for most purposes. From the records that do survive, it seems that Newton, like most other English officials, did not torture in the legal sense (for all that, it also seems plausible that at least a few of those in his custody suffered some bodily harm). He did not have to. The same reasons that led sovereigns to discontinue the practice would have held good for Newton too.
Yet the essential fact remains: Newton, only months removed from the life of a Cambridge philosopher, managed incredibly swiftly to master every dirty job required of the seventeenth-century version of a big-city cop. He found in himself the capacity to do what had to be done.
