Rachel Aviv Breaks Her Silence on Lucy Letby — Why the Nurse’s Case Felt Like a ‘Myth Playing Out in Real Time’ to the Journalist Who Dared to Question the Evidence
Rachel Aviv spent years examining the evidence behind Lucy Letby’s convictions — and her questions sparked fierce debate. Now, as Aviv revisits the themes of motherhood, memory and contested stories in her new book, she explains why the Letby case felt to her like something far bigger than a conventional criminal investigation.
For Rachel Aviv, the Lucy Letby case was never simply another crime story.
The New Yorker staff writer became one of the most prominent journalists to question aspects of the evidence surrounding the British nurse’s convictions after publishing a lengthy investigation in 2024.
Her reporting examined thousands of pages of court transcripts, police interviews, text messages and internal hospital records. The article questioned whether some of the evidence presented against Letby had been interpreted too confidently and whether alternative explanations had received sufficient attention.
The result was explosive.
For supporters of Letby’s convictions, Aviv’s reporting was deeply controversial.
For those who had already questioned the case, it became a powerful reason to look again.
And now Aviv has offered a glimpse into why the story affected her so deeply.
“A myth playing out in real time”
In a recent interview, Aviv described Letby’s story as feeling like “a myth playing out in real time.” She said the case struck her because ambiguity appeared to have been difficult for the public to tolerate.
That observation goes to the heart of Aviv’s approach.
The Letby case produced an extraordinarily powerful narrative: a neonatal nurse working around critically ill babies, a series of deaths and collapses, a striking timeline and prosecutors arguing that one person was the common factor.
Letby was eventually convicted of murdering seven babies and attempting to murder six others at the Countess of Chester Hospital.
But Aviv’s reporting argued that the apparent simplicity of the story concealed complicated questions about medical evidence, statistics and the interpretation of events.
The story that shocked Britain
When Aviv investigated the case, she encountered a prosecution narrative that had already become deeply embedded in public consciousness.
Letby had been portrayed as a trusted nurse who secretly committed horrific crimes.
Yet Aviv noted an apparent contradiction: people who had known Letby described her as caring and professional, while police had reportedly found little in her background that provided an obvious explanation for why she would kill babies.
That contradiction became one of the questions Aviv wanted to explore.
How could someone who appeared ordinary to colleagues become the central figure in such an extraordinary criminal case?
And perhaps more importantly:
What happens when a compelling story begins to overshadow the uncertainty surrounding the evidence?
The evidence became the battlefield
Aviv’s New Yorker investigation focused heavily on the evidence.
One particular issue was a chart used by police to show the relationship between suspicious incidents and nursing shifts.
According to Aviv’s reporting, Letby appeared as the only nurse with an uninterrupted sequence of shifts associated with the incidents.
Prosecutors argued that this pattern was powerful evidence.
But Aviv questioned whether the chart adequately accounted for other factors that could influence the number and timing of medical emergencies on the neonatal unit.
That distinction is crucial.
A pattern can look extraordinary.
But determining what caused the pattern requires considerably more than simply observing that it exists.
Then motherhood changed Aviv’s perspective
Aviv’s new book, You Won’t Get Free of It: Stories of Mothers and Daughters, published in 2026, examines complicated relationships between mothers and daughters through seven essays. Six originated in pieces she had previously written for The New Yorker and were reconceived for the book.
The Letby essay is not included in the collection.
But Aviv has said that becoming a mother changed the way she approached stories involving mothers and daughters.
That personal transformation gave her another lens through which to examine questions about family, memory, identity and competing versions of the truth.
And that makes her reflections on Letby particularly intriguing.
Why mothers became central to the bigger question
The stories in Aviv’s new collection explore what people inherit from their families, what gets concealed and what eventually becomes impossible to ignore.
The publisher describes the book as an exploration of the competing dynamics of knowing and not knowing, recognition and refusal, and how those forces shape family relationships.
Those themes inevitably resonate with the Letby controversy.
The case involved parents trying to understand what happened to their babies.
It involved medical professionals interpreting frightening events.
It involved investigators reconstructing events years after they occurred.
And it involved competing interpretations of records, memories and evidence.
For Aviv, those tensions appear to have reinforced a broader journalistic principle:
certainty should not automatically replace complexity.
The question of medical records
One reason the Letby investigation became so contentious was the enormous volume of technical evidence involved.
Medical records had to be interpreted.
Expert opinions had to be compared.
Witness recollections had to be examined.
And events separated by months had to be reconstructed into a coherent chronology.
Aviv’s reporting drew from more than 7,000 pages of court transcripts as well as hospital records.
That level of documentation can create an impression of absolute certainty.
But thousands of pages do not necessarily mean thousands of independent pieces of proof.
The meaning of each document still depends on context.
A case that refuses to become simple
That may be why the Letby story continues to generate such fierce debate.
There are two very different questions.
One is whether Letby was correctly convicted by the jury that heard the evidence at trial.
The other is whether every element of the case has been understood correctly and whether legitimate questions about the evidence deserve continued examination.
Aviv has concentrated heavily on the second question.
That does not by itself establish that the convictions were wrong.
But it does explain why her reporting has become such an important part of the continuing public debate.
The controversial article that changed the conversation
When Aviv’s New Yorker article appeared in 2024, it challenged what had become an overwhelmingly dominant narrative surrounding Letby.
The magazine itself framed the investigation around a provocative question: Did Letby do it?
The article examined disputed aspects of the prosecution’s case and highlighted concerns about statistical reasoning, medical testimony and the interpretation of evidence.
The reaction was immediate.
Some readers saw the piece as necessary investigative journalism.
Others saw it as an unfair challenge to convictions involving the deaths of vulnerable babies.
That divide has never entirely disappeared.
What Aviv is really questioning
Despite the sensational headlines surrounding her work, Aviv’s argument is not simply that one side of the story should replace another.
Her reporting instead asks whether investigators, experts, journalists and the public can become so convinced by a compelling narrative that contradictory information becomes harder to see.
That is a much broader question than Lucy Letby.
It concerns how humans process uncertainty.
How memories change.
How patterns are recognized.
And how emotionally powerful stories can influence the interpretation of complicated evidence.
The “myth” behind the headlines
When Aviv described the Letby story as a myth, she was speaking about its extraordinary narrative power.
A seemingly ordinary nurse.
A neonatal unit.
A sequence of unexplained medical emergencies.
A shocking accusation.
A courtroom conviction.
And a public desperate for an explanation.
It became a story with almost all the ingredients of a modern crime narrative.
But real investigations are rarely that neat.
They contain uncertainty, incomplete information, competing interpretations and unanswered questions.
That may be precisely what Aviv believes deserves closer attention.
Three years later, the debate continues
Letby’s convictions remain a matter of intense public scrutiny.
The wider inquiry into the Countess of Chester Hospital has also examined how concerns were handled and how the institution responded to warnings.
Meanwhile, Aviv’s work has helped ensure that questions about the evidence remain part of the international conversation.
Her new book demonstrates that her interest in contested stories extends well beyond one criminal case.
It is ultimately about something more universal:
how people decide what to believe when the truth is complicated.
Rachel Aviv’s most uncomfortable question
Perhaps that is why the Letby story still follows Aviv.
Her investigation did not provide a simple alternative explanation for every disputed event.
Instead, it challenged readers to sit with uncertainty.
And that can be far more uncomfortable than a definitive answer.
The central question surrounding her work is therefore not simply whether Rachel Aviv believes Lucy Letby is innocent or guilty.
It is whether the public should ever stop questioning the evidence simply because a story has become emotionally convincing.
For Aviv, that appears to be the lesson that extends far beyond one controversial case.
Because when a real-life investigation begins to resemble a myth, the most important question may be the one nobody wants to ask:
What if the story everyone thinks they understand is still more complicated than it appears?
