Topical for a change as, although written in the 1960s, it deals to some extent with Scottish Nationalism. This George Gently detective story deals with a murder in the Highlands while the policeman is on holiday with Brenda Merryn, his sister and his brother-in-law. There's death, imprisonment, adultery and betrayal included and it reads quite well even if a lot of the dialogue is in Scottish brogue and needs some effort to comprehend.
