Saint-Pierre cast: Who stars alongside Joséphine Jobert?

by

Joséphine Jobert, known for her role in Death in Paradise, has left the show, but she’s now starring in a new crime drama that fans of the genre are sure to enjoy.

In the series, Saint-Pierre watches Jobert step into a key leadership position as Arch, a complex deputy chief with a mysterious background and a strong desire for answers while she learns the ropes in France. Allan Hawco, who also co-created, co-showruns, and executive produces the show, joins her as Fitz, a newcomer to the region who arrived after uncovering sensitive information about a politician.

Okay, so the setup is really intriguing. It sounds like this movie throws together two cops who couldn’t be more different – they’ve both got years on the force, but their styles are totally opposite. And, of course, they’re paired up to crack some really unusual and captivating cases. I’m already hooked just from that little bit!

The islands appear like a charming getaway, but this peaceful image hides a dark side of criminal activity that often surfaces in such beautiful places. Initially, Arch and Fitz distrust each other, but they quickly realize they work better as a team.

Allan Hawco as Sergeant Inspector Donny “Fitz” Fitzpatrick

Fitz is a newcomer to Saint-Pierre and Miquelon, adjusting to his new job while dealing with personal challenges. He was previously very successful working undercover, but it came at a great cost to his relationships and family – something he misses. He’s hoping his new life on the island will offer a fresh outlook.

You might recognize Allan Hawco from his appearances in popular shows like Tom Clancy’s Jack Ryan, Republic of Doyle, Moonshine, and Sullivan’s Crossing. These are some of his most well-known roles.

Joséphine Jobert as Deputy Chief Geneviève “Arch” Archambault

Arch is a highly intelligent and analytical police officer known for her confidence and attention to detail – she doesn’t miss a single clue. With a background in law and having lived in Paris and the UK, she’s a straightforward and perceptive investigator who arrived in Saint-Pierre for reasons she keeps to herself.

You probably recognize Joséphine Jobert from her popular role as Florence Cassell on the TV show Death in Paradise, where she was a main cast member for several seasons. Besides acting, she’s also appeared in French films and TV and has a career as a singer.

You might recognize Benz Antoine from his roles in police and legal dramas. He’s appeared in shows like Rookie Blue, 19-2, Blue Murder, and Reasonable Doubt.

James Purefoy as Sean Gallagher

Let me tell you about Sean. He’s Irish, and trust me, he’s not someone you want to cross. The guy seems to have his fingers in every pie – politics, shipping, you name it, he’s involved. But it’s more than just business, you get the feeling he’s mixed up in some really shady stuff, and I have a feeling we’re only seeing the tip of the iceberg.

Wondering where you recognize James Purefoy? He’s a British actor who’s appeared in popular shows like HBO’s Rome, A Discovery of Witches, Pennyworth, and Sex Education.

Erika Prevost as Patty Montclair-Ito

I’m really rooting for Patty! She’s always dreamed of being a police officer, and while it’s true her parents have connections in the force – she’s definitely earned her spot in Saint-Pierre. She’s incredibly driven and wants to learn everything she can to become a great officer. It’s awesome to see her so dedicated to proving herself.

Many people are wondering where they recognize Erika Prevost. Besides playing a role in Saint-Pierre, she’s also appeared in the series The Boys and the teen drama Dare Me.
