Edge (Tim Ellis) Books in Order

The Edge series starts with a sharp, no-frills premise. In The Serial Killer's Apprentice, a dismembered young woman is found buried in Kielder Forest, and two other women have already been taken. That is bad enough. The real pressure comes from the fact that the investigation has to be shared by two police forces and by two senior detectives with history.

DCI Harriet Hogg is from Northumbria. DCI Tanner Edge is in charge on the Penrith side. Neither the case nor the partnership promises to be easy. Ellis leans into that tension straight away. This is not a cozy team-up. It is a joint task force built under stress, with old personal friction sitting right beside the professional urgency of stopping a killer before more women disappear.

That gives the series a leaner feel than some of Ellis's bigger ensemble books.

The setting also helps. Kielder Forest and the wider northern landscape add isolation and unease, and the case itself carries the weight of something unfinished. The murders may connect to a crime from twenty years earlier, which means the detectives are not only chasing a current threat. They are also working against memory, old mistakes, and whatever was missed the first time around.

If you like police thrillers built on jurisdictional tension, personal history, and a genuinely dangerous serial case, Edge has a strong hook. It feels tighter and more direct than Ellis's most sprawling series, but it still has the same interest in damaged investigators and ugly truths that refuse to stay buried.
