Line of Duty recap – Who is ‘H’, is he Ted Hastings and who are the other main suspects?

THE main question that seems to plague viewers is Who is ‘H’ in Line of Duty? It’s the question that’s continued to intrigue audiences well into series five, with AC-12 on the hunt for the corrupt police officer at the heart of the BBC crime drama.

But who are the main suspects?

What do we know about ‘H’?

  • The letter ‘H’ was first mentioned in in Dot Cotton’s dying declaration.
  • However, could this be the first letter of a name i.e. Hastings, Hilton or could it be a codename as suggested in the series.
  • He seems to be a senior in the police force able to communicate with corrupt police officers and keep his name out of the investigation.
  • We also know he communicates with the balaclava gang by instant messenger to preserve his anonymity.
  • Another clue is that he spells “definitely” with an ‘a’ that could also give away clues about his accent. He has also benefited financially from balaclava’s lucrative crimes.

So now that we have the evidence down, let’s take a closer look at the suspects.


Les Hargreaves (Tony Pitts)

Hargreaves’ surname began with H, and he also held a senior position in the police force which is clue number two.

During the series he has repeatedly admitted that he was never a big fan of AC-12, and at this point it’s crystal clear that he’s at least “bent”.

The first “corrupt” signs came to light around season two, but he never seemed especially equipped to be a criminal mastermind.

However, he might be working very closely with ‘H’ as he seems familiar with his ways.

Stephen Graham

Ted Hastings (Adrian Dunbar)

It took Line of Duty’s creator and writer Jed Mercurio four season’s to tarnish Ted Hasting’s reputation by spreading some serious doubt around his character.

It all happened around the end of season 4 when Hastings’ laptop pinged with an instant message just after we saw Lisa and John Corbett (Stephen Graham) using IM to talk with ‘H’.

In addition, an unknown number calling Lisa McQueen’s mobile just as Hastings was ringing a number which didn’t pick up.

As we know Hastings has been struggling financially for the past two seasons, after a property investment in Ireland went wrong and his wife left him.

So he could be ‘H’, however the show’s creator is implicating him so heavily that it seems a bit too easy.

Derek Hilton (Paul Higgins)

Here’s another senior police officer with a surname beginning with ‘H’. Derek Hilton is a Deputy Chief Constable and was a prime suspect.

Before his death, Hilton was shown to be involved with the balaclava gang and was one of the highest ranking police officers to be implicated.

In one episode he arranged to have Steve killed by a balaclava man at Nick Huntley’s offices, and he blackmailed Maneet to get vital documents and files from AC-12.

Hilton is now dead and ‘H’ is still active.

So while he was on the corrupt side he probably is not ‘H’ unless he has an excellent copycat executor or rises from the dead.


Alison Powell (Susan Vidler)

A new name to the suspects’ list is Alison Powell, who is on first-name terms with Ted Hastings, and was placed in charge of a mission to place undercover officer John Corbett inside an organised crime group.

As far as we know, she has kept her actions out of AC-12’s sight with a Mopi notice to block the files on the police database, and failed to report that Corbett had gone Awol for months.

She repeatedly avoided to cooperate with AC-12, and key information is missing from the files.

It seems likely that Powell is implicated in some way, but we don’t know in what way.

Also, we don’t want to state the obvious but there’s no H in her last name.


‘H’ mystery

At this point in the series, the show’s creator has implicated so many character plotlines that anything goes.
