PATRICK Barlow’s inventive comedy thriller The 39 Steps – the one with four fearless actors, 139 parts and 100 minutes of chaos, calamity and one cool head – returns to York next week on its first tour in eight years.

Ahead of its return to the West End, the Tony and Olivier Award winner plays the Grand Opera House from July 23 to 27, with a cast led by Tom Byrne, whose credits include Netflix series Bridgerton and Black Mirror and the role of Falklands war-era Prince Andrew in The Crown.

On the road from April to August 3, after a two-week launch in Hornchurch, Byrne plays old-school handsome hero Richard Hannay, replete with the stiffest of upper lips, boundless English pluck and unflappable pencil-slim moustache as he hurtles through encounters with dastardly murders, double-crossing secret agents and devastatingly beautiful women in Barlow’s dapper and dastardly clever fusion of taut thriller and comic release.

“We’ve toured to about 20 theatres, doing a bit of a [theatre architect] Frank Matcham tour so far, playing some incredibly beautiful theatres, and it does seem to sit nicely in all sorts of spaces, especially the more classical ones, like the Grand Opera House” says Tom. “We’re now 120 performances into the tour, so we’ve got over that first night thing!”

Combining novelist John Buchan’s 1915 secret-service thriller Thirty-Nine Steps with a helter-skelter, harum-scarum attempt to re-create Alfred Hitchcock’s 1935 film The 39 Steps – notable for introducing a music hall turn, a noir-cool blonde, handcuffs and the Forth Bridge to the story – Barlow’s comic caper must be steered by a short-handed cast of Byrne’s Hannay, Safeena Ladha’s Annabella Schmidt/Pamela/Margaret, Eugene McCoy’s Clown 1 and Maddie Rice’s Clown 2.

Not only must Byrne’s Hannay navigate his way through the hairpin bends of Buchan’s book and Hitchcock’s film, but also he finds himself murder suspect number one when a mysterious German woman, Annabelle Schmidt, dies in his arms after insisting on leaving the London Palladium by his side, desperate to impart vital information.

“I’d never seen The 39 Steps when I read the script, but immediately Patrick Barlow’s script struck as me as being very witty, reminding me of a lot of the British comedy I grew up with,” says Tom.

“It ticks loads of boxes, being quintessentially a spy thriller, where Patrick then weaves in the metatheatrical elements of storytelling.

“My part, amidst all the hilarity, is a very layered, three-dimensional character, and I just really responded to its combination of plenty of laughs but plenty of psychological drama too – and it’s quite romantic!”

In the opening scene, Hannay has newly returned to his lonely Portland Place abode, tired of life and its mounting pile of problems. Feeling anything but alive in 1935. Suicidal even. “Patrick’s play is thought of as this really quite cosy, beloved, light-hearted comedy, but it begins with this monologue that welcomes you into the drama with a man on the edge of ending things,” says Tom.

“It’s quite remarkable that in spite of that opening, the play manages to maintain its levity, but without its potential for seriousness, it would count for nothing. That’s part of my job: to make sure the truth of the story can be honoured, which then enhances the comedy. You have to have those high stakes.

“What’s kind of surprising is that Patrick has been quite loyal to the film, then he adds another layer of enjoyment for those who love their Hitchcock as we create ‘Eater egg moments’ with nods to his other films.”

“I always felt I had a character like this in my locker,” says Tom Byrne

Tom is full of admiration for Barlow’s imagination in creating comic mayhem that nevertheless flows like a David Gower cover drive. “It’s a testament to how well it’s written that it’s so seamless in managing to make all the different elements happen simultaneously, yet for the performers it feels pretty simple when we’re on stage- thought maybe that’s because I’m playing just one role!” he says.

The comedy may be British in character, “but there’s also so much that’s universal: so much of that visual style of comedy is available for anyone from eight to 80 to enjoy. There’s something that’s completely approachable about the comedy for anyone from any background,” reckons Tom.

Playing Richard Hannay takes Tom’s acting into new territory. “I haven’t done anything like this before; it’s been very new for me though I always felt I had a character like this in my locker, having an affinity for such characters from growing up loving Blackadder, which was one of my reference points – loosely – for the role,” he says.

“I haven’t had the chance before to play someone like Hannay for a sustained period, which has been great to do– and it’s also changed over time, beginning with certain intentions and then you do 120 shows, and it becomes a process of trial and error, where the audience somewhat guides you in certain decisions. Instinctively you learn what seems to be working better.”

To finish, the subject matter turned to Tom playing Prince Andrew from the age of 22 to 32 in The Crown, against the backdrop of the “Epstein Scandal” playing out across the media. “I didn’t really have to engage with it,” he says. “To be honest, it was surreal. The Newsnight special [the Emily Maitlis interview] happened at that time, and I made a point of not watching it.

“But doing The Crown was a great experience and I was incredibly lucky to work with the people I did.”
