Time to say goodnight to Napoli, from that timeless classic Buona Sera Signorina by Louis Prima lends itself to the title of a series of Mediterranean Noir tales set in the Naples of the nineteen seventies. In the first of the series, you can follow the exploits of a detective who wants to make a difference, but is a little reticent about doing so.
