I think I would have enjoyed this book more if I had the print version to read. I’ve realized that GADF reads can be hit or miss when it comes to my connection with the voice narrator, and this one didn’t quite grip me. I also blame myself for multitasking a bit too much while listening. I loved the threatening letters, the impossible crime element, and the humor throughout. I fully intend to reread this title as a physical copy one day because I think it should probably have been a 4-star read.
