This book is best enjoyed over a long period of time (so 3 days for me), letting all of the tension seep into your bones. Alternating between chapters from a manuscript and feedback from a critique partner, Sulari Gentill builds a story riddled with anxiety as Freddie attempts to solve a locked door murder in the Boston Public Library. But rather than sit in the library for the entirety of the story, they're able to leave its confines and that's where the story truly begins. All of the characters are compelling and likable in their own ways, and each given a good reason to be suspected. My only qualm is with how rushed the ending was - I didn't feel as though all of the motivations were fleshed out enough. However it's all worth it for the final passage from Leo (one of my favorite characters honestly!)

I'd recommend this to fans of Agatha Christie who want a little bit more darkness in their mysteries.
