The Investigation of Lucy Letby (2026)

Quartile rating: 6/10 · 1 rating

An engaging and thought-provoking look at Lucy Letby, the former nurse serving life in prison after being convicted of the murders of seven infants and the attempted murders of seven others.

The Quartile Take

A true crime documentary centered on one of the UK's most disturbing modern cases, The Investigation of Lucy Letby benefits from its deeply unsettling subject matter and raises genuine questions about how a trusted healthcare professional could commit such crimes. The narrative structure is engaging and thought-provoking as advertised, covering the investigation and trial competently. However, as a documentary it lacks dramatic performance elements beyond talking heads and archival footage, keeping Acting modest. Cinematography is functional rather than distinctive, typical of the true crime genre. Novelty is slightly above average given the unique and harrowing nature of the Letby case itself, though the documentary format follows familiar true crime conventions. The ending is adequately resolved given the life sentence outcome, though it leaves lingering unease about motive and institutional failure, which is fitting for the subject.
