CQFD - Or, c'était la nuit

A single-issue French comic from Casterman, CQFD - Or, c'était la nuit (2002–present) is a self-contained, poetic graphic novel that unfolds over the course of a single night. It uses its limited page count to create a moody, atmospheric narrative, likely exploring themes of memory, solitude, or urban reverie. The series' unusual format—a single issue spanning years of potential release—makes it a distinctive, standalone work in the European comics landscape.
