John Corbett was a UCO embedded in the OCG under Operation Pear Tree, which is being investigated by AC-12.

John was seeking out the senior bent copper with links to organised crime, who goes by the codename ‘H’.

Maneet Bindra passed on confidential AC-12 documentation to ACC Derek Hilton, which was then given to the OCG.

She claimed she didn't know and was protecting her cousin Vihaan who had a gambling habit, under blackmail from Hilton.

While trying to make amends to AC-12, by going undercover, John found a bug in her burner phone.

Maneet was killed by the OCG at 'murder dock' where Hilton's body was found before.

John Corbett tortured the gaffer’s wife for information about Ted, who he claimed was the top man 'H'.

John was then killed by the OCG for being a rat. OCG member Lisa McQueen seemed pretty torn up about his death.

While communicating with the OCG via a computer link, Ted used the same misspelling of definitely (definiately) as 'H'.

Hastings conducted an unauthorised undercover operation, claiming to investigate links between the OCG and Central Police.

The SIO of AC-12, Ted Hastings, has been arrested on suspicion of conspiracy to murder John Corbett.

He is being investigated by the top woman of AC-3, Patricia Carmichael.

Ted maintains that he’s being framed. Patricia is determined to prove that he’s 'H'.

Ted Hastings lost a significant amount of money through a bad investment. He's now living in a hotel.

Ted was lured by Mark Moffat into meeting to discuss an investment to recoup his losses. The buy-in was £100k.

£50k in cash was discovered in Ted’s hotel room, which Mark had given him in a brown envelope.

Ted was also seen disposing his laptop. This definately all seems quite dodgy.

Back at AC-12, Kate, Steve and Tatleen are all working tirelessly to uncover the truth.

In fact, Tatleen is the unsung hero of their investigations, diligently searching for evidence.

All in all things are pointing to the fact that someone somewhere is a bent copper.
