When is it possible to say for sure that an author is one of your favourites? How many of their books do you need to have read before you can make that claim? Even after reading His Bloody Project, I was sure that Graeme Macrae Burnet would be in a position to earn that title. Then I read Case Study and it only confirmed how much I enjoy his writing. In order to get the full experience, I also bought copies of his other works but, as usual, it took me a while to get around to them. When I found the audiobook version of this book in my library’s catalogue, it seemed like it was the right time to do so. So, I listened to it during work with the hope that I could finally bestow the all-important title on the Scottish author.
