Arrogant and bad-tempered, Vezzi was hated by many, but with the livelihoods of the opera at stake, who would have committed this callous act? Ricciardi, along with his loyal colleague, Maione, is determined to discover the truth. But Ricciardi carries his own secret: will it help him solve this murder?
