After an explosive episode of Coronation Street, we finally know who killed Theo Silverton (James Cartwright).
The murder mystery has rumbled on for months, and shows no signs of stopping – while us viewers are privy to the murderous information, on-screen, only Gary Windass (Mikey North) is privy to the truth.
A telling flashback exposed Sarah Platt (Tina O’Brien) as the resident with blood on their hands, which explains the secret that she and Gary have been keeping for weeks.
“She’d gone looking for Todd, she rang him, she could hear this phone on the scaffolding, so she went up and there was Theo,” O’Brien explained.
“She said some things that were pretty threatening so then he wouldn’t let her leave. The way he was talking, it sounded like he’d done something to Todd – as in he was dead – that’s how it felt to Sarah, that he’d done something awful to Todd.
“He was coming towards her, and I think in that moment, as far as she was concerned, it was do or die.”
Of course, if (or rather when) the rest of Weatherfield’s community discover what has happened, Sarah could be looking at facing some pretty serious consequences.
“There was a lot of debate in the green room as soon as we were told there was going to be a murderer,” O’Brien continued.
“A lot of people were playing Cluedo, first off some of the cast got told that they were involved in the storyline, but they weren’t the murderer. So by the time it got to me to go for my meeting, I was a bit like, ‘I think it’s me!'”
She added: “I genuinely didn’t worry, at the end of the day this job is incredible, but to be an actor is not necessarily a job for life. So, I just was really excited to be given the honour of being the murderer, and then hopefully, however it plays out, I’ll enjoy Sarah’s arc.”
When posed with the idea that Sarah could be imprisoned for her crime, O’Brien acknowledged that it could spell the end for her character.
“She could be going to prison this time,” she said, referring to the time she was accessory to Callum Logan’s murder in 2015.
“If she’d have called the police straight away and explained what happened, she would have been in a much better situation, because it was clearly not pre meditated, it was a situation where she felt she had no other choice.
“But to cover it up, to actively cover something up, she knows that she crossed a line that she can’t come back from.”
The actress, who joined the soap in 1999, also revealed that Sarah will be pushed to the brink and consider handing herself in.

“It’s not just about her now, it’s about her family and her son, and there are times when she can’t cope with the pressure and you think she’s just going to hand herself in.
“And then she thinks about her son growing up without a mum, if she’s convicted and can’t prove she acted in self defence. And because of those things, she’s so desperate to do whatever it takes to be part of her family’s life.”
