Carlyss Peer as Kate Miskin

Carlyss Peer returns in Dalgliesh Season 3 as Kate Miskin. She was Dalgliesh's partner at work but got promoted from DS to DCI by the end of Season 2. Peer mentions about her role this season,

She is more in charge than she was before. She’s upping her game and her responsibilities. So it’s a new time for her.”

Peer has previously appeared in projects such as The Great Escaper, Sense & Sensibility, and Beyond Paradise.

Alistair Brammer as Daniel Tarrant

Alistair Brammer plays Dalgliesh’s sidekick, DS Daniel Tarrant. In the first episode of Season 3, Tarrant mentions he has been accepted into a different program. However, before joining the program, he must help Dalgliesh solve the the murder of an Archdeacon.

Regarding his role, Brammer says,

“It’s really nice returning to a character because you start off on the front foot. You’re not trying to figure out who this guy is. You’re literally putting on the same pair of shoes, and also metaphorically a familiar pair of shoes.”

Brammer has previously starred in A Call to Spy and Casualty.

Sam Swainsbury as DCI Clive Roscoe

DCI Clive Roscoe is played by Sam Swainsbury, who describes the character thus,

“Roscoe is an interesting contrast to Dalgliesh in so much as he is an open, kind family man with two little kids. He is very much devoted to his job and has a very keen eye for investigation.”

Swainsbury has previously starred in projects such as Mum and Hanna.
