Dalgliesh
Bertie Carvel plays P.D. James's brooding detective-poet Commander Adam Dalgliesh in this atmospheric period adaptation, set in 1970s England and shadowed throughout by Dalgliesh's private grief over the death of his wife. The first three seasons each adapt three of James's novels across six hour-long episodes, unfolding at the same unhurried, literary pace as the books themselves; Season 4 will bring the show's first original, non-novel story. Dalgliesh streams on Acorn TV in the US.
Is This Series for You?
Fans of Slow-Burn, Literary Mystery
Viewers who want their detective drama to breathe — Dalgliesh favours mood, period detail, and psychological complexity over fast-paced procedural beats.
Three Novels, Six Episodes, Per Season
The first three seasons each adapt three P.D. James novels, with each novel told across two hour-long episodes, for six episodes per season. Season 4 shifts that formula slightly, pairing two novel adaptations with the show's first entirely original story.
Somber Rather Than Graphic
Dalgliesh deals in grief, institutional secrecy, and murder, but leans on atmosphere and psychology rather than graphic violence. British TV Hub's verdict: a handsome, faithful showcase for one of crime fiction's most literary detectives.

Best Cases, Ranked
Shroud for a Nightingale
The series premiere, sending Dalgliesh into the closed world of a nursing school after a student nurse is poisoned during a training exercise — a strong showcase for the show's institutional-secrecy storytelling.
The Black Tower
Dalgliesh visits an old friend in Dorset only to learn he died days earlier, pulling him into the suspicious world of a care home for the disabled.
A Taste for Death
Two bodies are found in a London church vestry — a recently-resigned Tory MP and a homeless man — in one of Season 1's most politically charged cases.
Death in Holy Orders
Dalgliesh travels to a remote seminary overlooking a windswept lake, where a body has been found gruesomely murdered — and nearly everyone has a motive.
Devices and Desires
Dalgliesh is sent on an urgent mission to investigate a terrorist plot against a nuclear power station on the Kent coast, only to be drawn into a hunt for a serial killer.
Main Characters and Cast
Bertie Carvel
Commander Adam Dalgliesh — a published poet and Metropolitan Police detective, recently widowed and quietly grieving throughout the series.
Carlyss Peer
DS/DCI Kate Miskin — Dalgliesh's sergeant across the first three seasons, rising through the ranks alongside him. Her return for Season 4 has not been confirmed.
Sam Swainsbury
DI Clive Roscoe — Dalgliesh's new colleague for Season 4, introduced as a guest character in Season 3 before becoming a regular.
Jeremy Irvine
DS Charles Masterson — Dalgliesh's sergeant in the first season, before Kate Miskin becomes his regular partner.
What Makes the Series Special
Faithful to P.D. James
The series has worked steadily through James's acclaimed Dalgliesh novels, preserving the 1970s setting and the character's identity as a published poet as much as a detective.
Bertie Carvel's Interior Performance
Carvel plays Dalgliesh's grief and detachment with restraint, letting the character's poetry and private sorrow surface quietly rather than dramatically.
A Convincing 1970s England
Season 3 pushes into the start of the Thatcher era, using its period setting to explore the wider social and political implications behind each murder.
Setting and Filming Locations
1970s England, Filmed Across the UK
Dalgliesh is set across 1970s England, with each novel's story moving to a new location — a nursing school, a Dorset care home, a London church, a Kent nuclear power station. Season 3 filmed in Northern Ireland, doubling for the English settings of its source novels.
Books Behind the Series
P.D. James's Adam Dalgliesh Series

James novels per season through its first three seasons: Season 1 covers Shroud for a Nightingale, The Black Tower, and A Taste for Death; Season 3 covers Death in Holy Orders, Cover Her Face, and Devices and Desires.
