Berlin, December 1918. The Kaiser has fled, revolution fills the streets, and the German Empire lies in ruins. Oberstleutnant Alaric von Trelow returns from the trenches to find his world transformed. The old order is dead, red banners hang from every building, and communist revolutionaries clash with returning soldiers in blood-soaked streets. When Prussia's crown jewels vanish from the royal palace, von Trelow is given a secret mission that will thrust him into the heart of Berlin's chaos. Going undercover among the revolutionaries, the aristocratic Guards officer must navigate a deadly world of political extremists, criminal gangs, and desperate men willing to kill for a fortune in diamonds. But as the city erupts in violence and rival factions battle for Germany's future, von Trelow discovers that some loyalties run deeper than duty-and that the price of honour may be higher than he's willing to pay. In a Berlin where no one can be trusted and yesterday's enemies are today's allies, loyalties shift like smoke and survival may depend on trusting those you hate. As the violence escalates and time runs out, von Trelow must find a path between duty, honour, and violently competing visions of the new Germany. A gripping new historical thriller set in the crucible of Germany's violent birth as a republic-where honour, betrayal, and deadly secrets collide in the rubble of an empire.
