I love the covers of old paperback novels. The 60s and 70s were a golden age for jacket designs like this
This is the cover of the Fontana paperback of Reginald Hill's 1970 crime novel, A Clubbable Woman. This was Hill's debut, the first to introduce his chalk and cheese detectives Dalziel and Pascoe. As they attempt to solve the murder of a rugby player's wife, their investigations discover that she was just that little but too friendly with the rest of the squad.
In my teens I used to devour Hill's books, spurred on by the TV debut of his creations in 1996. A Clubbable Woman was the first book to be dramatised for the BBC in what proved to be a long running series starring Warren Clarke and Colin Buchanan.
