The Blame Ending Explained: Who Killed Sophie Madsen — and the Full Cast

A 16-year-old figure skater is found dead, and the detectives assigned to find out why end up investigating their own police station. That is The Blame, and if you are watching it on ITV1 you are one episode in with a fortnight to go.

🔑 You do not have to wait. All six episodes went up on ITVX on launch night.

Where to watch The Blame, and how far ahead you can get

The broadcast run pairs up across three weeks: episodes one and two on 20 and 21 September, three and four on 27 and 28 September, five and six on 4 and 5 October. Subtitles and a British Sign Language version are both available on ITVX.

Who is in The Blame cast?

Keegan’s Crane is the one officer in Wakestead willing to name what is wrong with the station she works in. Booth plays Radley as the likeable one — which the series is doing on purpose.

It comes from Quay Street Productions, the company behind Happy Valley, and is adapted by Megan Gallagher with Ashley Sanders and Namsi Khan, from Charlotte Langley’s 2023 debut novel — a book shortlisted for a Crime Writers’ Association Dagger. Bex Rycroft and Claire Tailyour direct.

The real texts

One production detail is worth knowing before you start, because it explains the tone of the first ten minutes.

The misogyny in the Wakestead canteen is not invented dialogue. The drama incorporates messages sent by real police officers, brought to light through whistleblowing. Booth has described opening the series that way as a deliberate choice, and both leads have said the original version of that opening was re-filmed because it was judged too explicit.

That is the argument the series is making in its first scene: the murder plot and the culture are the same story.

What happens in each episode?

⚠️ These are ITV’s own summaries. The series went up a day before this was written, and detailed accounts of the middle of the run have not been published yet — so rather than fill the gap, this section gives what the broadcaster says and stops there.

How episode one ends

Safe to read if you have watched Sunday’s episode; skip to the next heading if you have not.

Dashcam footage shows that Sophie got into Tom Radley’s car less than an hour before she died. It does not show why. That single piece of evidence turns one of the two lead detectives into a suspect in the case he is working, and hands Emma an investigation she cannot run without investigating her partner.

🔴 Full spoilers from here. Everything below gives away the ending.

If you are following on ITV1, the finale does not reach you until 5 October.

Who killed Sophie Madsen?

It is not the man the investigation spends most of its time chasing, and it is not the man the finale exposes as a serial abuser. Those are two different people, and neither sentence is a slip.

It is DI Tom Radley.

The detective the series spends six hours making you like is the one who killed her — and his reason has almost nothing to do with Sophie.

The two revelations, kept apart

This is where most summaries go wrong. They merge the two reveals into one man. The series has two, and the distance between them is the whole point.

Neil Shergill is the predator

He is the serial abuser the finale exposes: a man who drugged and assaulted Kacy Denson, Marissa Andrei and Amber Dodds — women who had come to the police for help. He also altered Sophie’s mobile phone records to hide how close she had got to him.

But he did not kill her.

Tom Radley is the killer

Years earlier, during the Marissa investigation, Tom worked out who Shergill was — and said nothing, because saying something would have damaged his own career. What began as silence became an arrangement between the two men, favours traded quietly over years.

Then Sophie found the photographs.

When she brought them to Tom, he recognised the man in them as the one he had protected. He followed her into Dankworth Forest. In the confrontation she fell and was hurt, and then was struck a second time, fatally.

🔑 So he did not kill her to protect a predator. He killed her to protect the cover-up — his own. Sophie’s evidence would have exposed Shergill, and exposing Shergill would have exposed Tom. That is what the title is about. The blame in The Blame is not the assault; it is everything the station did afterwards to keep it quiet.

What does Emma do?

She arrests him.

The finale puts her in the worst possible position — she has fallen for him, and she is the only person who can see it — and she does not flinch. There is no ambiguity in the last act about whether she will protect him.

There is one more turn before that. For much of the final hour the case looks solved once Emma identifies Shergill, and she asks him to help her trace a number used to contact Marissa, not realising she is standing in the house of the man she is hunting. Photographs found there indicate there were victims beyond the three named.

The bottom line

Two crimes, two men, and a series that is far more interested in the second one than the first.

The murder is solved in the finale. What is not solved, and is not meant to be, is the thing that made it possible: a station where a man could be recognised and then quietly left alone, because naming him would have cost a colleague his promotion.
