n Ilja Albrecht’s second thriller, Kalter Zorn (Cold Fury), profiler Kiran Mendelsohn and his uncompromising partner, Kommissar Bolko Blohm, are drawn far beyond Berlin when violence shatters the tranquillity of a small Westphalian town. The story begins in idyllic Xanten, where the murder of an American exchange student plunges the community into fear and places the German investigators under the scrutiny of U.S. authorities. Brutally abused for hours before her death, the victim bears the unmistakable signature of a methodical and deeply disturbed killer.

As Mendelsohn coordinates with the FBI and finds himself reporting to Quantico as well as his own superiors, the case quickly expands across borders. Database searches reveal chilling parallels to two identical murders in Virginia and North Carolina, suggesting that a serial killer has carried his campaign of violence to Germany. Forced into a long-dreaded return to the United States, Mendelsohn revisits unresolved cases alongside an old FBI colleague, while Blohm and the Berlin team race to prevent further bloodshed at home.

When another murder occurs on German soil and the killer initiates contact via online chat, the investigation takes a disturbing turn. Mendelsohn begins to question established serial-killer typologies and senses that the perpetrator’s true design is still unfolding. Blending transatlantic tension with psychological intensity, Kalter Zorn explores themes of obsession, accountability, and the inescapable pull of the past, pushing Mendelsohn to confront both a new kind of predator and the unresolved shadows of his own covert history.
