"The Stranger Diaries" by Elly Griffiths - this is a stand-alone novel by the author of the Ruth Galloway, and Stephens & Mephisto crime series, and is set in Sussex. Clare Cassidy teaches English at a nearby school, and also creative writing during the holidays, and at the same time is working on a biography of the author R M Holland, who used to live in the house which now forms part of the school's original premises, and in fact his study is still there, complete with many of his personal possessions. He once wrote a famous Gothic horror short story - The Stranger - which is gradually told throughout the book, but the modern day story which unfolds is just as frightening, when one of the other English teachers, and Clare's one-time closest friend, is murdered in her own home. Initially it's seen as either a break-in gone wrong, or that Clare knew her killer, but when another teacher is murdered, this time at the school itself, the police look more closely at the English department. The story is told in 3 different voices, Clare herself, then the detective sergeant who's in charge of the case - Harbinder Kaur, a likeable British Asian who still lives with her parents, loves her mum's cooking and is coming to terms with being gay, and Clare's daughter Georgia. I found the changes of narrator jarred slightly at first, once I got used to one voice it switched to another, but it was interesting to get a different perspective, although I thought Georgia was the weakest (and least used) narrator. But it was well-written and entertaining, if not quite as involving as the Galloway series, and the setting was good, and it felt like a real tribute to the Gothic genre, although it's bang up to date with references to modern popular culture, including a near obsession with Strictly Come Dancing! And even the dog is a major character, bless him. 7.5/10
