Dissociative fugue

Dissociative fugue is a rare dissociative condition in which a person may lose self-awareness, autobiographical memory, and a sense of identity. In the novel, Joseph Wieder’s diagnosis of Derek Simmons makes the condition central to the uncertainty around Simmons’s past: it could explain why he claimed not to remember his wife’s murder, but it also complicates how others judge his account of events.

Diagnosis and Possible Effects

Wieder concludes, after examining Simmons several times, that Simmons has a dissociative disorder and had been wrongly diagnosed with schizophrenia when he was young. He describes fugue states as episodes in which a person can lose awareness of who they are along with their memories and sense of identity. In extreme cases, someone might disappear from home, turn up years later in another city or state, and live under a new identity without recalling the former life. Some people return to their earlier identity but forget the life they made in the meantime; others remain bound to the new one.

Wieder’s explanation is presented as a diagnosis, not as certainty about Simmons’s actions. If it is correct, Simmons might not have remembered what he did on the night of the killing. Wieder proposes that stress and the altered state associated with an abrupt transition from sleep to waking could have led Simmons to react as though he were a different person. The conditional nature of that account matters: it offers a possible mechanism for a memory gap, but does not independently establish what happened that night.

Memory, Suggestion, and Testimony

Wieder’s account of fugue sits within a wider challenge to the assumption that a vivid recollection is a reliable record. He explains that memory can replace the source of an experience: someone may feel certain of having been somewhere, when the apparent memory actually comes from a story heard in childhood and the memory of hearing it has faded. Richard Flynn, for example, had long believed he remembered watching the 1970 Super Bowl, where the Kansas City Chiefs beat the Minnesota Vikings, although he had been only four years old; what he carried was his father’s repeated account of the game, mistaken for personal experience. Wieder contrasts memory with a camera, describing it instead as an active process that assembles a narrative from fragments and may alter what a person takes to be fact.

His mall experiment gives that theory a concrete and unsettling form. Wieder selected students who had grown up during the period when malls were becoming widespread, but none initially recalled getting lost in one as a child. Under hypnosis, he suggested that they had been lost. Three-quarters later reported memories of the supposed event, supplying details about their fear, clerks escorting them to their mothers, and announcements over the mall speakers naming children such as Tommy or Harry. Their childhood anxieties about being separated from their mothers gave the suggestion a plausible setting; a proposed childhood alligator attack in New York City, by contrast, would have lacked that familiar fear to support it. The experiment shows how a memory can feel detailed and personally owned while its supposed source is suggestion joined to an existing expectation.

The novel turns that uncertainty back upon the investigation. Flynn’s manuscript places his departure for Wieder’s house around 6 p.m., roughly twenty minutes after Timothy Sanders’s visit, while his account to investigators put the visit at about 9 p.m. and his return home at 10. The conflicting times leave open whether Flynn lied in one version or whether his recollection shifted; the discrepancy cannot, by itself, settle which account is true. Memory’s instability therefore does not belong only to a patient diagnosed with a dissociative disorder: it also shadows a witness whose movements matter to the murder inquiry.

Derek Simmons’s testimony is further weakened by the assumptions others bring to it. When he tells an investigator that he knows who killed Wieder and that he had reported what he saw at the time, he also anticipates that his earlier murder accusation and confinement in a psychiatric institution would cause authorities to dismiss him as unreliable. The investigator later recalls that Simmons had amnesia and was ill, and treats those facts as reasons his statement could not help the case. Simmons, however, insists that Frank Spoel might have forgotten or lied; when confronted with the differences between their accounts, he does not concede that his own memory is mistaken. The competing explanations remain consequential: a diagnosis may offer a reason for gaps in recollection, but it can also become a shortcut by which a witness is discounted, while conviction alone cannot verify what that witness remembers.

A Memory Breakthrough

After the hospital attack left Derek Simmons unable to recover his earlier memories, he could still use practical skills without remembering how he had learned them. Joseph Wieder arranged a place for him to live near the professor’s house and employed him as a handyman; Simmons could repair the old house, though he could not recall acquiring that ability. Wieder supervised his treatment, took him fishing, and spent an evening with him at least once a week. He also hypnotized Simmons at the university without telling him what the session had revealed.

In mid-March 1987, a news item on NY1 about a man from Bergen County who had died by suicide brought back a specific memory: Simmons recognized Stan Marini as a former member of the maintenance crew at Siemens. He also recalled that Marini had married around the same time as he had and later moved to New York. Simmons understood the recollection as something no one had told him and that he had not read; the return felt like a lid lifting from buried material, with memories surfacing at extraordinary speed. The episode gives the novel a concrete image of memory’s uneven return, but it does not establish that Simmons recovered everything he had lost or verify every account he gave of the past.

Narrative Significance

The novel places dissociative fugue beside other, distinct failures of recollection without treating them as interchangeable. Wieder’s diagnosis offers a possible account of lost autobiographical identity; his mall experiment shows how suggestion can generate a convincing memory; and Flynn’s conflicting accounts of when he visited Wieder expose uncertainty even without a diagnosis. Together, these cases unsettle the idea that a memory’s vividness, coherence, or confidence is enough to establish its source. They also leave an important distinction intact: an explanation for how recollection may fail is not proof of what happened. Fugue therefore deepens the murder inquiry’s uncertainty while making the act of judging testimony part of the mystery.
