Suspect two: Katy Sutcliffe (Zoë Tapper)

Katy, much like Carl, is behaving suspiciously. She’s told to “go home” when her colleague, Nick (Oliver Maltman), realises she’s been drinking heavily.

“I’m pretty sure I don’t need a breathalyser to tell me you’re still over the limit,” he says, preventing her from scrubbing up and going into surgery. “Go home. I’ll tell them you didn’t feel well, but you need to sort this out.”

Later, Katy calls her husband Liam (Richie Campbell) and informs him that she has an alcohol problem.

“I need to drink to get me through the day, every day, all the time,” she tells him. “I don’t know what to do.”

“That’s good,” he replies. “And you know what, I’m here. So I’ll help – however I can. We can find somebody you can talk to about all of this.”

This, however, is clearly not what Katy wants to hear.

“Stop being so bloody understanding,” she replies, before begging him not to tell Laura about the state she’s in: “I saw the news – she’s got enough shit to deal with.

It’s clear Laura is working through some past traumas, but we doubt it’s anything to do with Andrew’s murder, to be honest. Anyone else thinking that something entirely unrelated happened to Katy – who looked so happy and together just three weeks ago?

Suspect three: Branch Commander Greg Maxwell (Jack Colgrave Hirst)

As in, yes, DS Maxwell (Danny Webb)’s son.

Shortly after the season two premiere, one fan tweeted: “So I think Rory the cop did it. Because Andrew raped his mate (the copper woman who grassed Laura up) he also planted the key during the warrant search.”

Now, though, it seems Maxwell could have been trying to protect someone else: Greg. Aka his son, his pride and joy, and the apple of his eye.

We’re introduced to Greg (along with Kelly’s DI Renton) early on in the episode, in what seems to be a throwaway moment. However, Greg later approaches his dad and asks him to speak with him privately – which, in Liar world, means over a pint at the local pub.

It’s clear Greg has a lot on his mind. Could it be that the “rising star of the NCA” (National Crime Agency) played a part in Andrew Earlham’s murder?
