Line Of Duty SPOILER: Explosive trailer for series 6 finale teases ‘definately’ misspelling

Line Of Duty will be back on Sunday night and fans are eager to find out whether AC-12 will finally crack the case on the elusive H. 

And in a teaser released on Monday, viewers can be certain of an action-packed finale episode with a police standoff, the return of balaclava men and that ‘definately’ misspelling. 

The trailer starts off with Superintendent Ted Hastings (Adrian Dunbar), who is facing imminent retirement, state: ‘All of these suspicious deaths were orchestrated by one officer in particular, H. The fourth man.’

Hastings’ powerful words went alongside flashbacks of the deaths of solicitor Jimmy Lakewell, police officer Lisa Patel, journalist Gail Vella and former Detective Inspector Marcus Thurwell- whom fans believe is still alive.  

The trailer then shows acting Superintendent Jo Davidson (Kelly MacDonald) leaving the high-security prison in handcuffs, only to end up alone in a van with a corrupt prison officer who previously injured Lindsay Denton in series three. 

Jo says: ‘What’s going on?’, before the camera flashes a sinister look from the prison officer.  

A handwritten note is also teased in the trailer, with the word definite misspelt to mirror what viewers have seen previously.  

A huge clue of the identity of H began to emerge in series five, when the OCG communicated with ‘H’ through a computer.  

Eagle-eyed fans were quick to notice H spelling definitely as ‘definately’, and this misspelling has been repeated in subsequent episodes. 

Will this handwritten report be the breakthrough AC-12 need to close in on ‘the fourth man’? 

It certainly seems Hastings and his team are on to something as police cars speed down the road, while armed officers close in on a residential area.

The Superintendent briefs DI Kate Fleming, DI Steve Arnott and DC Chloe Bishop as they arrive at the scene.

Hastings says: ‘AFO’s will secure the suspect down’, while the words ‘Every investigation has led to this… H’.

And it only gets more dramatic as balaclava men jump out of vehicles armed with guns themselves. 

Kate opens the police van, brandishes her gun and shouts: ‘armed police’ before the screen fades to black.  

Viewers were stunned on Sunday night when it appeared James Nesbitt’s character was killed off before he even appeared on screen – but some are convinced it was a cover-up.

Towards the end of the nail-biting penultimate episode, Guardia Civil police officers stormed Marcus Thurwell’s Spanish home, while the AC-12 team watched via video link.

When the law enforcement officers entered the home, they were met by two bodies, and a Spanish captain turned to the camera and identified one as ‘Senor Thurwell’. 

While many viewers expressed surprise an actor of Nesbitt’s calibre was denied even a scene, some were left convinced Thurwell was in fact the Spanish AFO leading the raid on his home.

One tweeted: ‘Is it just me or was one of those Spanish “police officers” Thurwell? I’m sure it was him.’

Another wrote: ‘Exactly what I was thinking? Nice job if James Nesbitt only got paid for a few photos so I suspect that Marcus Thurwell is 100% alive.’

And one commented: ‘Is this Marcus Thurwell or have they just found the Spanish Jimmy Nesbitt to play the part?’ – sharing a series of screenshots to illustrate the likeness.

AC-12 were looking into the retired former detective chief inspector after SI Steve Arnott (Martin Compston) learned that Gail Vella – the journalist who was murdered – had been looking into the death of Lawrence Christopher while in police custody – a case Thurwell was in charge of.

Thurwell also has links to Darren Hunter, the son of former organised crime group boss Tommy Hunter.

The OCG also murdered Oliver Stephens-Lloyd before he had an opportunity to give evidence about sexual abuse at Sands View Boys’ Home, with Superintendent Ted Hastings convinced Thurwell is connected to the killing and the abuse cover-up. 

When Thurwell was found ‘dead’, Hastings was visibly exasperated – with time running out for him to solve the mystery before his impending retirement. 

Elsewhere in the episode, viewers learned PC Ryan Pilkington met a grizzly end, after working as an inside man in the Murder Investigation Team (MIT) for the Organised Crime Group (OCG). 

After being lured to a lonely car park by DCI Jo Davidson during the previous episode, Kate was met by armed officer Ryan who said he planned to kill her as he held up his gun and aimed it at her.

The episode ended as two gun shots sounded, before the new episode revealed that Ryan had been shot twice in the chest, with Kate and Jo fleeing the scene in a Thelma and Louise-inspired fashion.

When DI Steve Arnott arrived with the AC-12 unit they discovered that Kate and Jo had gone on the run and Ryan was dead. 

DCS Patricia Carmichael could be heard telling officers that the duo were considered to be ‘armed and dangerous’ and sent out an order for their address.

Despite the gripping hunt for Jo and Kate which commenced, fans were overjoyed that one of their favourite characters had survived.

Elsewhere during the new episode, fans were left convinced that Detective Chief Superintendent Patricia Carmichael is the fourth man after Sunday’s episode.

The officer, played by Anna Maxwell Martin, placed herself at the centre of the action as she ordered Kate Fleming to  be arrested following the shootout and then tried to shut down Ted Hastings’ questions during a very intense interview of Jo.

Some viewers even theorised that Carmichael was trying to send a message during the ‘puzzling’ interview – which also saw Jo discover her paternity despite offering more ‘no comments’ than answers – based on how often she tapped her pen.

This Morse code theory popped up during Arnott’s questioning of Davidson, specifically when he tried to get information about Gail Vella’s laptop and computer. 

Although Davidson remained tight-lipped, Carmichael did seem to start sweating a little as she tapped her pen four times and took a sip of water.

Morse Code is an alphabet that spells out words or messages using a series of short and long sounds, with the officer appearing to make four taps and spell out H.

Carmichael again set alarm bells ringing when she cut off Hastings at the end of the interview following his knockout question about Osborne being H.

Cutting off the AC-12 head’s question, she declared that Davidson was being charged with ‘perverting course of justice and misfeasance in public office’.

Elsewhere in the interview, Jo told her version of what happened during the shootout with Ryan Pilkington.  

Davidson told the other officers that it wasn’t Kate who killed the bent cop, but her using Kate’s gun. 

Even when Carmichael pointed out that the forensic evidence pointed to Kate being the shooter, Davidson had an answer saying gunshot residue must have been absorbed by Kate’s sleeve as she fired and insisting that she killed Ryan.

Carmichael was later seen talking to Kate as she finished up her own interview and teasing that she didn’t believe Davidson’s version of events.

She said: ‘Two shots to the chest, like a firearms trained officer. Davidson’s not firearms trained is she? But you are though aren’t you Kate?’
