Watch if you appreciate restrained, emotional true crime without sensationalism. This is not a detective story about finding the murderer — it is a story about how crime destroyed a child's life and how the system added trauma with its mistakes. Perfect for those seeking human drama within a crime story.
Premiere on Netflix took place on June 4, 2026 — all three episodes at once. "The Only Witness" is a British true crime miniseries based on the memoirs of Alex Hanscomb, "Letting Go." The story revolves around the murder of 23-year-old Rachel Nickell in July 1992 on Wimbledon Common in London. The only witness was her two-year-old son Alex, while her partner Andre Hanscomb had to protect the boy from a wrongful investigation and media storm.
The tone is intimate, emotional, without sensationalism. The series does not attempt to entertain the viewer with details of the murder: the focus is on the trauma of the child, the despair of the father, and how the justice system initially accused the innocent Colin Stagg, while the true murderer Robert Napper was found only 15 years later. Jordan Bolger plays Andre at different ages, while Max Fincham plays adult Alex, who himself served as a consultant for the project.
The format is 3 episodes of ~60 minutes, limited series. The script and creation are by Rob Williams, production by STV Studios. The filming recreates the atmosphere of the 1990s, and interviews with real participants in the events (in the documentary accompaniment "The Murder of Rachel Nickell") add documentary authenticity.
If you watched "Leaving Neverland" or "When They See Us" — "The Only Witness" operates on a similar wavelength: a crime story through the lens of the victims, not the perpetrator. Fans of British dramas like "The Fall" and "The Suspect" will feel comfortable, and for those looking for quality true crime without the shouting — this is one of the most restrained Netflix projects of 2026.
