That date is historical: it is not a forthcoming season 6 premiere. The series follows private detectives Cormoran Strike and Robin Ellacott as they investigate a murder involving the creator of a cult television cartoon and an anonymous online troll called “Anomie.” Tom Edge adapted the novel; Sue Tully directed the four-part series. WBD’s announcement credits J.K. Rowling, Neil Blair, Ruth Kenley-Letts and BBC’s Nick Lambon as executive producers.
What is confirmed about The Running Grave?
The Running Grave is the next announced adaptation, and it adapts the seventh story in the series. The official announcement confirms Tom Burke and Holliday Grainger return as Strike and Robin. J.K. Rowling’s announcement describes it as the next installment of the BBC crime drama, co-produced with HBO and Warner Bros. Discovery.

| Story | Source novel | Release status and timing | Official trailer information |
|---|---|---|---|
| Sixth | The Ink Black Heart | Four episodes; US HBO debut January 23, 2025, at 9:00 p.m. ET/PT; also available on Max. WBD announcement. | WBD’s property page dates the official trailer to January 16, 2025. |
| Seventh | The Running Grave | Upcoming adaptation; the official FAQ gives a 2026 broadcast window, without an exact date. | No trailer announcement is established by the official sources cited here. |
The distinction matters because “season 6” searches can surface the already-released The Ink Black Heart trailer even though readers asking about the next installment mean The Running Grave. Rowling’s FAQ says the television adaptations are based on the Strike books, which she writes under the Robert Galbraith name; it lists eight books published and two more planned.
