Yesterday I bought "The Suspicions of Mr Whicher", largely because I'd seen someone at work reading it, liked the title and then noticed it in the bookshop and decided to flick through it, rather than because I had any idea what it was about. Who needs fancy advertising techniques, anyway?
Luckily, it turned out to be brilliant - it's a detailed true account of an 1860 murder investigation, and what's best about it is the picture it gives of the very earliest days of police detectives. The developing vocabulary of detective fact and fiction is really fascinating, and the writer (Kate Summerscale) has a real knack for picking up on the little nuances of meaning in 150-year-old language. I'd recommend the book to anyone!
