This was a perfect throwback to the Agatha Christie era type of mystery novels. But this adds a really humorous twist. The book is written as a book by the main character. He swears to never lie and tells the truth as he knows it. I would recommend the audiobook. It is written as someone telling you a story, and the audiobook really works for that kind of storytelling. 

I'm not gonna say too much about the plot because I don't wanna give anything away. I had such a good time throughout the story and uncovering the mystery. The book is structured by each person story and does not necessarily follow a direct timeline. The pacing really allows you to pull back each mystery, and as it slowly unravels with pieces coming together, the book comes to an end with a satisfying conclusion.
