Lucy Letby was convicted of murdering seven babies and attempting to murder seven others while working at the Countess of Chester Hospital. She received 15 whole-life sentences, but the case did not end with the verdict. Letby has consistently maintained her innocence, and her convictions have since become the subject of intense scrutiny from lawyers, medical experts, journalists, politicians, and campaigners.Lucy Letby: The Countess of Chester Nurse takes readers inside the extraordinary investigation and courtroom battle surrounding Britain's most controversial modern criminal case. It examines the deaths and collapses that triggered the investigation, the prosecution's theory of what happened inside the neonatal unit, the medical evidence presented to jurors, and the arguments that ultimately led to Letby's convictions.But then came another chapter.An international group of medical experts has challenged significant aspects of the prosecution's medical evidence, arguing that natural causes and poor care could explain the babies' deteriorations. Letby's legal team has taken those arguments to the Criminal Cases Review Commission, which is examining whether the convictions should be referred back to the Court of Appeal.Meanwhile, questions surrounding the hospital itself have continued. A separate investigation into potential corporate and gross-negligence manslaughter at the Countess of Chester remains ongoing, while a coroner has opened inquests into five babies whose deaths were among those connected to Letby's convictions.The controversy has reached even deeper into the evidence. Reporting in 2026 revealed that a key prosecution expert had been under a medical fitness-to-practise investigation while giving evidence at Letby's trial—an issue that has become part of the wider debate over the reliability and presentation of the prosecution's medical case.Was Lucy Letby responsible for the deaths and collapses the jury attributed to her—or did investigators mistake medical complications and failures for deliberate murder? Were warning signs overlooked inside the hospital? And can a conviction remain secure when significant experts continue to dispute the evidence behind it?
