News from the television adaptations and Mick Herron’s publishers, arranged with the newest updates first. Each dated item links to its evidence and to a guide where you can read more. Production reporting is marked separately from official announcements, and upcoming releases retain their scheduled dates.

Watch the Quiet Snow is due on 22 October
John Murray’s publication date for Watch the Quiet Snow is 22 October 2026. The collection is forthcoming on 13 October. The publisher identifies five included works: The List, The Drop, The Catch, The Last Dead Letter and Standing by the Wall.
Readers choosing between editions can use the collection guide to compare those contents with the separately published stories. This is a gathering of shorter Slough House fiction, rather than the next numbered Jackson Lamb novel. The reading-order guide places the shorter works alongside the main sequence.

Series 7 filming reported complete
In its 7 October interview with Christopher Chung, Radio Times reports that the seventh series has been shot. That production update is labelled Reported: Apple’s commissioning announcement establishes the series and its source novel, while the filming status comes from press coverage. The report does not supply a premiere date for this guide.
An earlier Radio Times article, published on 16 June 2025 and drawing on Gary Oldman’s Deadline interview, said filming was expected to begin in late September or early October that year. The Series 7 hub collects the official production details separately from these reports. For now, the practical news is that the next adaptation is commissioned, with a reported completed shoot, rather than an announced transmission date.

Series 6 is arriving weekly
Slow Horses returned on 16 September 2026. Apple announced six Wednesday releases, finishing on 21 October. At the 13 October check, episodes 1–4 have been released: their dates are 16, 23 and 30 September, then 7 October. Episode 5 is next, on 14 October, followed by episode 6 on 21 October.
Series 6 draws on both Joe Country and Slough House. Gaby Chiappe adapts the season and Adam Randall directs. The weekly series guide distinguishes released episodes from those still coming up; the episode archive provides the wider viewing order. Recaps are reserved for episodes that have aired, with plot details behind spoiler controls.

Down Cemetery Road reached Apple TV
The Apple TV adaptation of Down Cemetery Road premiered on 29 October 2025. Emma Thompson plays private investigator Zoë Boehm, with Ruth Wilson as Sarah Trafford. Its opening mystery begins with an explosion in an Oxford neighbourhood and a missing girl; Sarah’s determination to find her brings the two women together.
This is another route into Herron’s writing, centred on civilian investigation rather than Lamb’s MI5 workplace. The book guide introduces the original Oxford novel and explains the television adaptation. If the series has prompted you to read more, the book archive separates the Zoë Boehm novels from Slough House, standalones and collections so that each sequence is easy to follow.

Apple commissioned Series 7 from Bad Actors
Apple announced a six-episode seventh series on 8 July 2025, naming Bad Actors as its source and Gary Oldman as returning star Jackson Lamb. The announcement identifies Ben Vanstone as television adapter and executive producer, with Robert McKillop directing. The story’s published starting point is a search for a mole within the British Government.
The Bad Actors guide covers the novel without revealing its outcome above the spoiler controls. The Series 7 page records the commissioning details for viewers who want the production news without reading the book’s plot. Apple’s announcement confirms the adaptation; it does not establish a release date or a complete episode-title list.

Mick Herron received the 2025 Diamond Dagger
Mick Herron was announced as the Crime Writers’ Association’s 2025 Diamond Dagger recipient on 23 January 2025. The award recognises sustained excellence and a significant contribution to crime writing across a career. It is distinct from an award for a single novel: Dead Lions won the CWA Gold Dagger in 2013, while Spook Street received the Ian Fleming Steel Dagger in 2017.
The Mick Herron author guide puts that recognition beside his Oxford mysteries, espionage novels and shorter fiction. Readers arriving through television can also follow the publication and recommended reading orders to explore the bibliography beyond the books already adapted for the screen.
