XIII #13

This volume from the original XIII series, titled 'The XIII Mystery: The Investigation,' is a companion piece that delves into the enigmas surrounding the amnesiac protagonist. Rather than continuing the main narrative, it presents a detailed dossier-style exploration of the clues, characters, and unresolved questions from the earlier albums, offering readers a chance to piece together the overarching puzzle. Published by Dargaud, this 13th tome serves as a meta-narrative supplement for dedicated fans of the classic Belgian spy-thriller series by Jean Van Hamme and William Vance.
