In a supermarket of Vigàta a theft is committed, the collection was removed in the night - a large sum - but there are no signs of bureau. The Borsellino Director appears a bit dangling, he feels called into question from the questions of Augello and Montalbano, in a word he is afraid. The next day purse is dead, hanged in his office. Suicide? Dr. Pasquano has some doubts; What hides behind that theft? And what did the manager denied? Meanwhile in a Vigàta apartment the corpse of a girl is found. She has been stabbed, to denounce the murder of the cohabitant, Giovanni Strange, who has an iron alibi. The two criminal facts touch the names of two powerful: Mr. Mongibello, administrator of the owner company of the supermarket, and Michele Strange, president of the Province, Father of John. As always in the yellows of Camilleri two stories chased each other, they cross, they separate and then return to intertwine. And Montalbano this time is to play hard: tight on the one hand from the superiors who say and do not say, on the other by the judge who does not see it as he, finally from the public guided opinion by Televigàata, decides to intervene in first person throwing A sea problems of conscience and guilt. And the picture suddenly recomposes it and appears throughout the uncomfortable truth of him.
