A wave of refugees has arrived on the Sicilian coast, and Inspector Montalbano and his team have been stationed at port, alongside countless volunteers, to receive and assist the newcomers. Meanwhile, Livia has promised their presence at a friend's wedding, and the inspector, agreeing to get a new suit tailored, meets the charming master seamstress Elena Biasini. But while on duty at the dock one late night, tragedy strikes, and Elena is found gruesomely murdered. Between managing the growing crowds at the landing, Montalbano delves into the world of garments, in the company of an orphaned cat, where he works to weave together the loose threads of the unsolved crimes and close the case.
