The Running Grave

The Running Grave is by far the best book in the Cormoran Strike series to date.
The seventh book in the series sees Strike and Robin investigate the Universal Humanitarian Church, with a view to extracting one of its members, at the request of said member's family. Robin faces her biggest challenge to date, as she goes undercover and joins the UHC.
Although the story is told from the POV's of Robin and Strike, there are many secondary characters, ranging from Strike's subcontractors to members past and present of the UHC.
The will they/won't they scenario continues. I'm giving nothing away.
I thoroughly enjoyed The Running Grave. It is a gripping, tense and engaging read. Coming in at over 900 pages, it is the longest of the Strike books, but where this series is concerned there's no such thing as too long, in my humble opinion.
