Silver Pebbles is the first crime novel I've read that's set in Switzerland, giving interesting insight into the country and culture. This was an easy and entertaining read, thanks to its vivid descriptions and seamless translation by Mike Mitchell. Unlike many police procedurals, the book doesn't feature a murder investigation. Instead, it provides a fresh approach by following police as they close in on a diamond-smuggling drug mule who has managed to become separated from his sparkling haul. The book focuses heavily on the main character, Inspector Hunkeler, with all his flaws, as he embarks on a search for the diamonds before the drug mule finds them again. It also follows the sewage worker who discovers the diamonds stuck in a blocked pipe - and his mistress, who has a few ideas of what to do with them. As expected, none of the characters have an easy ride. Silver Pebbles is a short read, but there's plenty going on and a lot of shifty characters, turning it into an (almost) one-sitting read for me.
