A body turns up on the plot next door to island policeman Enrico Rizzi. Who was the dead man, and what is the meaning of the precious red coral brooch that surfaces shortly afterwards ? Together with his  colleague Antonia Cirillo, Rizzi follows the trail of a singular piece of jewellery, from Capri’s sun-drenched gardens to the narrow alleys of Naples, to the masters of an ancient craft, and to the dark secrets of Italy’s former monarchy.
