Rome, one evening in May. The streets are full of vehicles and pedestrians. Inside the Ministry of Defense, supervised by the carabinieri, everything appears calm, but during an inspection, the lifeless body of a general is found. Everything suggests that it was an illness, yet the story does not convince Marshal Licata, a great expert in homicides, who begins to investigate. Several twists and turns will impose a halt to the investigations and the skein will only unfold in the last chapter, thanks to Licata's logical shrewdness and investigative intuition. The novel is the first chapter of the series "The investigations of Marshal Licata". It is aimed at a public who loves the Yellow genre, but also to those who wear a uniform and who by reading it, will be able to breathe a "familiar" air.
