XIII Mystery

A fourteen-issue spin-off series from the classic Belgian thriller XIII, XIII Mystery (2010–2018) from Dargaud Benelux delves into the hidden pasts of the supporting cast. Written primarily by Jean Van Hamme alongside Margreet van Muijlwijk and Van der Heide produkties, each volume pairs a different artist—including François Boucq, Olivier Grenson, and Philippe Berthet—to explore the backstory of a single character from the main series. This anthology format expanded the world of the original without advancing its central mystery, offering fans deeper context for the enigmatic figures orbiting the amnesiac protagonist.
