Two black cats, a book club, and a murderer. The Italian cozy crime novel that became an international bestseller.

In the center of Cagliari, Marcio Montecristo, a big fan of detective fiction, opened a small bookstore, Les chats noirs (named after two black cats that appeared one day at his door and whom he hesitantly adopted, Miss Marple and Poirot, who have become the store’s main attraction), specializing in the genre. This is also where the book club "The Tuesday Detectives" meets—a diverse but close-knit group of friends. In fact, a year ago, the club managed to help solve a case that no one believed would ever be solved. Now Inspector Angela Dimaze returns to ask for their assistance in a new investigation. Will "The Tuesday Detectives" manage to solve this case as well and help the police stop the murderer before they strike again? Pulixi delivers a book full of suspense and irony, which talks about books and pays tribute to the classics of the genre, turning readers into the true protagonists of the story.
