On 27 February 1933, an arson attack destroyed the Reichstag Building, home to the German Parliament. The attack was immediately blamed on a young Dutch Communist, but a number of documents would seem to suggest that the blaze was in fact an inside job, a diabolical plot deployed from within the Nazi Party itself.

Commissioner Sigfried Sauer is back, this time investigating the mysterious arson attack on the Reichstag in Berlin, events never narrated before in a thriller.

When the Reichstag goes up in flames, all too soon Adolf Hitler and Hermann Göring arrive on the scene, and they waste no time laying blame for the attack on the Communists, finding a scapegoat in a figure who today is almost unknown: Marinus Van der Lubbe. Within a few hours, the leader of the ever more powerful National-Socialist Party asks for and obtains a state of emergency. And only a few months later, he would be elected with a narrow majority, thus gaining full political power. But who really plotted the attack that triggered the most tragic series of events in the history of humanity?

The only one who knows the truth is a man who now lives in Vienna and who works as a night watchman, but who was once known as Commissioner Sigfried Sauer of the Munich police force. A few evenings prior to the blaze, Sauer is drawn to Berlin by an old contact of his, telling him that Rosa – the love of his life – has vanished into thin air in the capital of sin.

While the ex-commissioner tries to track Rosa down and untangle the thick web of deceit spun by conflicting political forces, history comes crashing down violently onto their lives.
