The Investigation of Lucy Letby

Built around the case of Lucy Letby, the former nurse serving life after convictions for the murders of seven infants and the attempted murders of seven others, this documentary sets out to examine rather than sensationalise. The subject is about as difficult as true crime gets, and the framing promises a thought-provoking account instead of a lurid one, with attention to how the case was investigated and understood and to the weight it carries for everyone it touched.

For viewers who follow serious true-crime journalism and want scrutiny rather than spectacle. It runs 1h 35m, a length that suggests focus over sprawl, and the pacing is measured and evidence-led. Expect sober presentation and material that is genuinely distressing by the nature of what it covers, so choose your moment carefully. Recommended for documentary audiences who prefer questions carefully posed to easy conclusions.
