The famous novelist Pippo Quester writes a chronicle of the crossword puzzle. Together with his admirer and protégé Zeno Porno, a comic author at Disney, he uncovers curious stories about visionary editors, brilliant crossword creators, great pioneers of the craft, and literary heavyweights. However, as Professor Quester and Zeno explore the intertwined fates of the crossword puzzle and comics, the sudden appearance of Mafalda, a mysterious student with a deep grudge and a homemade gun, plunges the two authors into their own, true puzzle. Paolo Bacilieri's "Fun" is a meticulously researched chronicle and at the same time a playful literary crime novel, a stunningly innovative and beautifully illustrated graphic novel that is as intricate and captivating as a crossword itself.
