More crimes and detective shenanigans are in store for the returning cast of Miss Scarlet and The Duke in Season 4. 

Miss Scarlet and The Duke follows the journey of Victorian London's first female detective, Eliza Scarlet, as she grapples with the ups and downs of police work alongside veteran inspector William Wellington. 

The British period drama premiered on Masterpiece on PBS on January 7. 

Every Main Cast Member of Miss Scarlet and The Duke Season 4

Kate Phillips - Eliza Scarlet

Kate Phillips reprises her role as Eliza Scarlet in Miss Scarlet and The Duke Season 4.

As the first Victorian London female detective, Eliza Scarlet has already proven that she has what it takes to solve cases and catch bad guys. 

At the end of Season 3, Patrick Nash offers Eliza a chance to spearhead her own agency in London, leaving behind her late father's detective agency. 

Season 4 opens with Eliza as the head of a new detective agency (she took the offer, yes!), but there is a twist. The season opener highlights the fact that Eliza has no other detectives to work with, and she only has an accountant as her lone employee. 

The new season is expected to dive deep into Eliza's work issues as well as (potentially) answering the question of whether or not she will finally get together with her old pal, William. 

Speaking with Masterpiece, Phillips teased what to expect about Eliza's new career trajectory, noting that she gets to "meet lots of new people:"

"Nash & Sons allows her to meet lots of new people. She’s always looking to get one step ahead so the more people she meets, the more opportunities she has."

Peaky Blinders fans may recognize Phillips for her role as Linda Shelby in the series. The actress is also known for her roles in Downtown Abbey and Wolf Hall.

Stuart Martin - William “The Duke” Wellington

Stuart Martin returns as William "The Duke" Wellington. 

William is a veteran detective who was trained by Eliza Scarlet's father. The character is clearly infatuated with Eliza throughout the first three seasons even though he had a girlfriend named Arabella in Season 3. 

While Eliza's detective agency is in shambles at the start of Season 4, it is quite the opposite for William. The Duke, as many call him, is busy with more cases than he can ever handle. 

William and Eliza reunite in Season 4's first installment, with the latter teasing that he may need reinforcements after a stockpile of cases in his department.

Martin previously appeared in Army of Thieves, Rebel Moon: Part One - A Child of Fire, and Jamestown.

Felix Scott - Patrick Nash

Felix Scott plays Patrick Nash, Eliza's work rival who later turns out to be an eventual ally. 

While Nash is not impressed with Eliza at first, he eventually learns to respect her as a colleague and a friend in the latter part of Seasons 2 and 3. 

After Eliza accepts Nash's offer to take over Nash & Sons, the pair now works hand-in-hand together at the start of Season 4. 

In the same interview with Masterpiece, Scott teased that "Eliza and Nash get into a lot of trouble" in Season 4: 

"Eliza and Nash get into a lot of trouble. That’s their thing, that’s their M.O. There’s a lot more running around, there’s a lot of capering which is going around which is lots of fun."

Scott has credits in Our House, The Crown, and The Interceptor.

Cathy Belton - Ivy Woods
