The Man Who Was Thursday by GK Chesterton
A poet by the name of Gabriel Syme stumbles across the most dangerous anarchist cell in the world. Fortunately for the world, Syme is not simply the humble poet he appears, and has a chance to end the devilish plans of the cabal. Unfortunately for Syme, the first anarchist he sets his sights on isn’t what he appears either, and Syme spirals into a surreal conspiracy.
I love this book. It is mad and intelligent and well written, which are the three things I usually look for (and, as evidenced by the vast majority of books I’ve written about here: fail to find…)
Go read this book. It’s important.
