Shaun Dooley leads the guest cast in the Grace series finale – episode 4's Find Them Dead – in an ambiguous role that sees him play against type.

Viewers are used to seeing him most often portray decent 'every man' characters, but here he's allegedly corrupt solicitor Terry Maxwell – in a gripping courtroom-based thriller that also brings along impressive guest stars from Industry, EastEnders, Star Wars: Andor and Young Wallander for the ride…

What happens in the Grace series 5 finale, episode 4, Find Them Dead?

Grace is hoping to nail a crime boss known as The Merchant. A drugs bust provides his team with a name, Terry Maxwell, a solicitor known for getting petty criminals off the hook.

Maxwell is arrested but when it comes to his court hearing, someone appears to be applying pressure to the jury and witnesses to ensure he goes free.

Meanwhile, Cassian has yet more revelations to deliver. Revelations that will clearly reverberate through Grace series 6.

Who guest stars in Grace series 5, episode 4?

Shaun Dooley guest stars as Terence Maxwell

Terence Terry Maxwell is an urbane, mild-mannered solicitor, specialising in legal aid work, who helps his clients to find legitimate career paths after successfully representing them.

Or is he really The Merchant? The drugs lord that Grace is desperate to nail? Thats for a court to decide.

Maxwell is played by Shaun Dooley, an actor its nigh-on impossible you wont have seen in something, because he seems to be in everything. Even if you dont know the name, you will know that face.

Recently hes been starring in the Alan Carr biographical sitcom Changing Ends, playing young Alans football manager dad, Graham Carr.

He also had a major role in 2024s most talked-about drama, Mr Bates Vs The Post Office, playing Michael Rudkin, one of the post office workers wrongly convicted of embezzlement. In the mini-series, Rudkin visits the headquarters of Fujitsu where he learns how its possible for IT engineers to remotely access the Horizon system used by sub-postmasters.

Shaun was also in the Peter Capaldi-starring, hard-boiled cop show Criminal Record on Apple+ last year as racist, bent copper DS Kim Cardwell.

And thats just the tip of the iceberg. Hes also had multi-episode stints in the Channel 4 sci-fi series Misfits (2012-2013) as probation worker Greg; supernatural kids show Wolfblood (2014); season two of Broadchurch (2015) as Ricky Gillespie, the father of two victims in the Sandbrook murder case; and Gentleman Jack (2019-2022) as Jeremiah Rawson.

Catherine Walker plays Barbara Maxwell

Beauty salon owner Barbara is Terrys proud wife, mother to Ellen. Once a client of Terrys, always a client of Terrys, she tells young Wesley at the start of the episode. But she says it in such a way that it doesnt sound so much like a promise, as a threat.

Barbara is played by Dublin-born Catherine Walker, who was cast as another woman behind the throne in director Ridley Scotts 2023 movie Napoleon. She played Marie Antoinette, and her crazy-wild pre-execution barnet was about as historically accurate as anything else in the film.

She played another real-life figure in another Ridley Scott movie – Vogue editor Anna Wintour, in House of Gucci (2021).

On TV, shes has had multi-episode stints in various top-notch dramas, including series 5 of Shetland (2019), Versailles (as Madame Scarron, 2017-2018) and a starring role in the Sky medical drama Critical (2015) alongside Lennie James.

Georgina Rich appears as Meg Magellan

Shortly after waving her daughter off on her globe-trotting adventures, Meg is called upon to perform jury duty at the trail of Terry Maxwell. Then she starts receiving anonymous threats from someone who says her daughter will die unless she makes sure the jury rules in Terrys favour.

That must have been a heart-stopping moment for Meg, whos played by someone else whos familiar with a heart stopper (feel free to groan).

Georgina Rich, who stars as Meg, also plays Jane Spring, the self-obsessed mother of gay teenager Harry Spring in the Netflix coming-of-age drama Heartstopper (2022-2023). Not a bad mother as such, just one who isnt in tune or alert to to the traumas her children were going through.

Last year she also turned up in three episodes of the BBCs Jenna Coleman-starring thriller The Jetty, and five episodes of the same Apple+ cop series that Grace co-star Shaun Dooley appeared in – Criminal Record. In that series she played Assistant Chief Constable Claudia Mayhew.

Then there was a four-episode stint in the BBC and HBOs Industry (2024) where she played the Chief Financial Officer of Pierpoint, Wilhelmina Fassbinder.

Before that she had guest appearances in dramas as diverse as The Bill (2005), Waking The Dead (2011), New Tricks (2013), Sherlock (2014), Ripper Street (2014), Black Mirror (Hated In The Nation, 2016) and Call The Midwife (2018).

Sule Rimi plays Stephen Wolfe

Stephen Wolfe is the barrister working for Team Grace trying to secure the conviction of Terry Maxwell. He spends much of the hearing more worried that Roys going to do something reckless that will derail proceedings.

Although Roys old boss Cassian may have already thrown a spanner in the works…

Maxwells barrister, Primrose Morley, takes no prisoners, Stephen tells Roy. You can expect her to milk the fact that while this investigation was carried out, Cassian Pewe was in charge The fish rots from the head down, will be her line of attack.

Fun fact – Sule Rimi, who plays Stephen Wolfe – trained as a lawyer. You might think makes him prefect for this role, except that he trained as a property lawyer. He can also speak the African language, Hausa.

You may have seen Sule Rimi last year in Skys massively successful adaptation of The Day Of The Jackal, starring Eddie Redmayne. He played Paul Pullman, the university professor husband of Bianca Pullman (Lashana Lynch), the agent on The Jackals trail.

Sule also had a small role in the Star Wars TV series Andor, as Lieutenant Gorn, an officer in the Imperial Army local garrison on Aldhani.

Other roles include parts in Welsh crime drama Cleddau/The One That Got Away(2024), Death In Paradise (2019), Birds Of A Feather (2017) and Unforgotten (2015).

Josef Davies appears as Daniel Danny Starr

Danny Starr is using his day job as a classic car dealer to smuggle drugs into the UK by hiding them in the spare tyre of his Petersen Dartmoor (thats a make of car, in case youre not a petrolhead). When Grace nicks him, he gives up Terry Maxwells name as the crime boss hes working for.

Like Sule Rimi, Josef Davies appeared in the Star Wars TV series Andor, but its unlikely they rubbed shoulders as Davies played a prisoner on Narkina 5 called Xual.

Xual played a key role in the great escape, when he and another inmate, Ham, staged a brawl that distracted the guards, allowing Andor to jam a lift and kickstart the uprising. Xual, sadly, never made it out alive.

Josef also appeared in several series two of Young Wallander (2022) as the Soren, a wrongly convicted murderer fresh out of jail, doing his own investigations.

Other roles include part in the movies 1917 (2019) and the live-action Dumbo (2019).

Howard Saddler in the role of Sam Makerson

Sam Makerson is one the members of the jury. He puts himself forward as foreperson for the jury, saying: As a former DCI with Hampshire Police, I think I make the running.

The actor who plays Sam, Howard Saddler, is fresh off a recent run on EastEnders where he played Pastor Gideon Clayton from 2023-2024. When he first arrived, he seemed a decent enough man of the cloth.

Then he sexually assaulted Yolande Trueman, and it became clear that he was a serial offender. Clayton killed himself after his crimes were exposed.

Hes also recently had small roles in fantasy streaming series The Witcher (2023) and Amazons My Lady Jane (2024).
