D.I. Sam Cobbs is M.A. Comley’s largest single series to date, running to 41 books between 2018 and 2025 across two distinct naming phases. The earlier books use straightforward crime titles – No Right to Kill, Killer Blow, The Dead Can’t Speak, Cold Mercy – while the later run from 2021 onward adopts the “To” naming convention: To Die For, To Silence Them, To Make Them Pay, and so on through to The Truth Will Out in 2025.
The Cobbs books are set partly in the Lake District, with several entries in the “To Believe the Truth” strand specifically labeled as Lake District thrillers. This geographical grounding gives a distinct flavor to parts of the series compared to Comley’s more generically urban British procedurals.
A significant portion of the early Cobbs books also appear in the D.I. Sara Ramsey series, making the two deeply interconnected. Readers who pick up either series will inevitably encounter the other, and working through the two in parallel is a reasonable approach for anyone who wants to experience the full scope of Comley’s mid-2020s detective universe.
