📝 Description: Mater Vivens

Bjorn Nielsen’s debut novel introduces readers to the Mulligan Files series through a chilling mystery set in Dublin during the winter of 1926. The narrative follows Matt Mulligan and his assistant Maggie O'Sullivan as they investigate the disappearance of a child from the Glasnevin orphanage. What begins as a standard case quickly reveals itself to be something far darker, involving forces that defy simple explanation. As the Garda Siochana struggles with the case, daily press reports complicate the investigation further. Mulligan and O'Sullivan pursue leads that take them deep into the subterranean layers of religious faith. The story examines themes of fanaticism and obsession, pushing the detectives toward truths that society prefers to ignore. Nielsen draws on early twentieth-century Irish history and gothic traditions to create a tense atmosphere where the supernatural bleeds into the mundane. This volume suits readers who enjoy procedural mysteries grounded in historical settings with strong supernatural elements. It appeals to those interested in the intersection of law enforcement and religious institutions during the 1920s. The book may not satisfy readers seeking lighthearted entertainment or purely secular detective fiction, as the tone remains consistently grim and focused on dark spiritual conflicts.
