Il commissario Ricciardi. Serenata senza nome

Vinnie Sannino left Naples for America and became World Boxing Champion. But then, he decided to come back home for the woman he loves. Unfortunately, she got married to a rich merchant. And when this man is found dead, likely struck by a deadly punch, Vinnie is the prime suspect.

It's up to chief Ricciardi and agent Maione to lead the investigation under the never-ending autumn rain.
