Psychological Lock-Box Type Mystery!
This preview makes it seem that this book will truly be a kind of fever dream who-dun-it. The fun, such as it will likely be, will be in the gradual unraveling of the mystery of whether Cohen had something to do with his father's death, rather than the answer. Chapters look like they will be going back and forth in time, which should make for an interesting mix of past and present as it teases out Cohen's childhood, the way his relationship with his dad developed, and his actions post the discovery of his dad's body. This sounds like a very interesting psychological mystery!
