The Hallmarked Man is the eighth novel in the Strike series by Robert Galbraith and is set to be published on 2nd September 2025 with a page count of 912 pages. The audiobook is again narrated by Robert Glenister.

Synopsis
A dismembered corpse is discovered in the vault of a silver shop. The police initially believe it to be that of a convicted armed robber – but not everyone agrees with that theory. One of them is Decima Mullins, who calls on the help of private detective Cormoran Strike as she’s certain the body in the silver vault was that of her boyfriend – the father of her newborn baby – who suddenly and mysteriously disappeared.
The more Strike and his business partner Robin Ellacott delve into the case, the more labyrinthine it gets. The silver shop is no ordinary one: it’s located beside Freemasons’ Hall and specialises in Masonic silverware. And in addition to the armed robber and Decima’s boyfriend, it becomes clear that there are other missing men who could fit the profile of the body in the vault.
As the case becomes ever more complicated and dangerous, Strike faces another quandary. Robin seems increasingly committed to her boyfriend, policeman Ryan Murphy, but the impulse to declare his own feelings for her is becoming stronger than ever.
A gripping, wonderfully complex novel which takes Strike and Robin’s story to a new level, The Hallmarked Man is an unmissable read for any fan of this unique series.

Epigraphs
In an X post by J.K. Rowling on August 29th 2024, we found out that at least one of the epigraphs for The Hallmarked Man would come from A Maid of the Silver Sea by John Oxenham, a novel which is set on Sark in the Channel Islands. She later stated that the epigraphs for the book would come from five different sources.
Another of her X header photos was that of a quote from The Golden Journey to Samarkand by James Elroy Flecker. We don’t know for sure yet whether this will be an epigraph source or not.
