Two deaths – the suicide of a recently fired worker and the murder of an unscrupulous businessman – lead Inspector Montalbano to the Halcyon, a mysterious ship that visits Vigàta’s port each day. With very few crewmen, no passengers, and a stern large enough to land a helicopter, it piques the Inspector’s interest straight away. In the midst of this, a rare trip to Genoa to visit Livia ends with the Vigàta police department in disarray, and Inspector Montalbano’s position as the head of the commissariat in jeopardy.

It will be up to Montalbano to fix the damage done.
