I have to wind him up
Mr. Mercedes“I have to wind him up” is K. William Hodges’s compact description of a calculated effort to keep Mr. Mercedes engaged in online conversation. The phrase turns an uncertain investigation into a contest of bait and response: with few other avenues open, Hodges must provoke the killer without letting the killer recognize the provocation. It names a method, but also its danger. To make Mr. Mercedes talk, Hodges has to enter the very exchange in which either man could become the fish.
The problem of the exchange
Hodges sees the correspondence as a high-stakes choice rather than an ordinary attempt to gather information. If he writes the wrong message, he fears he will never hear from Mr. Mercedes again. Yet the obvious approach—making coy, clumsy efforts to discover the man’s identity—is precisely what he believes the killer expects. Mr. Mercedes is too intelligent to be treated as a gullible suspect, and Hodges knows that a transparent fishing attempt could leave the investigator exposed instead.
The alternatives available to Hodges are sharply limited. He cannot call on his old police resources, and the letters Mr. Mercedes sent to Olivia Trelawney and Hodges himself provide little help without a suspect to connect them to. A letter remains a one-way communication; computer chat offers dialogue. That distinction matters because an ongoing exchange gives Hodges a chance to elicit a response, but it also gives Mr. Mercedes room to read and manipulate him. The conversation is not merely a channel for evidence: it is the only practical instrument Hodges believes he has.
Choosing a lure
Hodges considers presenting himself as suicidal. The performance seems plausible because, until recently, he really had been drawn toward death. He believes that writing about the attractiveness of dying would keep Mr. Mercedes talking for a while, but he also asks himself how long such a pose could work before the killer saw through it. The idea therefore depends on a dangerous overlap between deception and personal history: Hodges can imitate despair because it is not wholly foreign to him.
He does not mistake his intended target for an easy mark. In his estimation, Mr. Mercedes is an intelligent person who is also crazy, not a credulous fool who would believe an implausible police promise. That assessment governs the choice of bait. Hodges cannot simply offer an obvious hook; he must give the killer a reason to answer while preserving the appearance that the conversation is proceeding on the killer’s terms. His phrase for the task, written in large capitals on a fresh page of his legal pad, is “I HAVE TO WIND HIM UP.” He boxes the words, files the pad in the case folder, and leaves them there as a working instruction.
A deliberate provocation
The phrase becomes an active strategy rather than a private note when Hodges explains to Janey Patterson that he is going to use her computer to send another message. He has already worked one out, but is considering adding something because his partner has made a major solve that day and Hodges sees a way to use it. When Janey asks what the breakthrough was, he tells her: Turnpike Joe. The new investigative result offers material with which to make the message more pointed; the exchange can be shaped by events outside the online correspondence itself.
Janey recognizes the tactic in Hodges’s own terms, recalling that he called it winding Mr. Mercedes up. Her response is not to urge restraint: she tells him to send another message and poke the killer harder, because he deserves it. Hodges agrees, thinks, and begins typing. The movement from boxed note to composed message shows how the expression organizes action: first Hodges identifies the need for a lure, then he uses a fresh piece of information to refine it, and finally he sends a further provocation with Janey’s encouragement.
Meaning and limits of the phrase
“Wind him up” carries a double sense in the episode. It suggests setting another person in motion, coaxing out a reaction, but its bluntness also exposes the danger of treating a violent, perceptive adversary as if he were a mechanism Hodges could simply control. The investigator’s own questions—who is the fish, and who is the fisherman?—keep that uncertainty at the center of the plan. Hodges needs Mr. Mercedes to respond, yet every message risks giving the killer an opportunity to take control of the exchange.
The wording also links the strategy to vulnerability rather than detached police procedure. Hodges considers using the language of suicidal despair because he has only recently emerged from a period in which death appealed to him. That history makes the proposed lure credible, but it means the deception draws on an actual weakness rather than an invented persona. The phrase is thus both tactical and self-exposing: winding up the killer requires Hodges to approach a state of mind he has not long left behind.
The expression’s force lies in the unresolved balance it names. Hodges is no longer simply waiting for contact; he decides to provoke it, adapting the message as new information arrives and accepting Janey’s encouragement to intensify the pressure. But the plan offers no guarantee that the intended target will remain the one being manipulated. “I have to wind him up” is therefore not a claim of mastery. It is a statement of necessity under risk, the working principle of an investigation that has become a dialogue—and a contest over who can make the other speak.
