Somme Stations by Andrew Martin. WWI mystery set around the 17th Battalion of the Northumberland Fusiliers, aka the "Railway Pals" (many of whom are far from pally with each other) made up of men employed by the North Eastern Railways who were detailed to the Western Front. A bit reminiscent of Ben Elton's
First Casualty, in that it deals with the solving of a murder almost lost amid the slaughter of thousands, but Martin has his own distinctive style, touched with wry, northern humour. His hero Jim Stringer is a dogged, bloody-minded Yorkshireman, who almost qualifies for the "dour" tag. Martin has a great eye for the small pertinent detail and the idiosyncratic Yorkshire character. Engrossing, but like its hero, a novel of determined persistence rather than flash and dash.
Although it can be read as a standalone, I discovered that this is the 7th book in a series, but typically, our library hasn't bought any of the earlier ones
