"In life, sometimes a subtle breeze is enough to demolish your elaborate card house. Then you realize that maybe you misjudged your priorities."
For Inspector Gert Zimmermann, however, this "subtle breeze" was the murder of the great benefactor, Alphonse Zauber. Because of this event, he is forced to cancel his planned vacation with his family, which will cause a major explosion. Now, the fact that he has taken on the case of the decade leaves his wife and children cold, who only care about having him close to them. As if that wasn't enough, the case goes from bad to worse. The pressure from his superiors is enormous and the evidence they have at their disposal is occasional and insignificant. As for the suspects, they are either invisible or nonexistent. All of this until a mysterious man appears who changes all the facts."

Stathis Vlachakos focuses on the person behind the investigation, delineating with great accuracy the character of Gert Zimmermann; his obsessions, his motives, his effort to balance between duty and desires. However, the author does not fail to build an interesting plot, which with its twists keeps the interest unabated until the last page. The reader follows the case through the eyes of the inspector and is called upon to answer the crucial question: Was he guilty?"
