In this novel the events that combine between them are three: the trade of paintings in which Marian is committed, Tunisian's arms trafficked while in their homeland the liberation struggle is underway, the robbery suffered by Loredana and the Murder that is followed: what will the right direction to solve everything? But it is not the only surprise that "a blade of light" reserve. In fact, we will find a character of the first novels, and it will not be a little question.
