Deadly Rivalries new in the Nico Agenti series

A tragic death at a betrothal ceremony embroils Nico Argenti in the precarious world of Renaissance Florence’s elite.

Guests are gathered at a villa in the Tuscan countryside to celebrate a betrothal that would unite two powerful Florentine families. The joyful atmosphere is shattered when the groom-to-be is discovered murdered. 

Florentine Security Commission member Nico Argenti, himself a guest, is charged with finding the killer, suspected to be an invited guest or a member of the villa staff. The investigation exposes Nico and his colleagues to the jealous motives of guests and a chain of interconnected crimes. Each revelation in the case, ranging from bribery and theft to tax fraud and assault, contributes to its growing complexity.

 Is simply identifying the killer enough to guarantee that he will face the consequences?

Deadly Rivalries is the sixth book in the award-winning Nico Argenti Renaissance mystery series. It may be read standalone.
