Here are two classic mysteries, each a part of an excellent series.
On Reginald Hill and his series:
The “master of . . . cerebral puzzle mysteries” sends his Yorkshire detectives back to college to be taught a lesson in murder (The New York Times).
Reginald Hill “raised the classical British mystery to new heights” when he introduced pugnacious Yorkshire Det. Inspector Andrew Dalziel and his partner, the callow Sgt. Peter Pascoe (The New York Times Book Review). Their chafing differences in education, manners, technique, and temperament made them “the most remarkable duo in the annals of crime fiction” (Toronto Star). Adapted into a long-running hit show for the BBC, the Gold Dagger Award–winning series is now available as ebooks.
