XIII Mystery

A thirteen-issue spin-off series from the classic Belgian thriller XIII, XIII Mystery (2008–2018) from Dargaud Benelux delves into the hidden pasts and secret histories of the series' key supporting characters. Rather than advancing the main storyline, each standalone volume focuses on a single figure—from the enigmatic Jones to the ruthless Irina—exploring their origins and motivations through the work of a rotating team of European talents. Writers like Van der Heide produkties and Margreet van Muijlwijk, alongside artists such as Corentin Rouge and Olivier Grenson, expand the world of the amnesiac assassin, offering fans a deeper, more textured view of the conspiracy that defines the original series. It matters as a thoughtful, character-driven expansion of a modern classic, rewarding longtime readers with essential context without ever spoiling the core mystery.
