Jim Fist composes a thrilling detective novel, a subversive and sarcastic parody in the style of Sir Arthur Conan Doyle, the creator of the mythical Sherlock Holmes. The backdrop features the Paris Commune and the defeat of the rebellious Communards of 1871, as well as a plethora of imaginative characters who love the poetry of Baudelaire and Byron, the dialectical thinking of Hegel, and the literary greatness of Shakespeare and Goethe.
