The comic series was created on the heels of the success of
fumetti neri such as
Diabolik and
Kriminal by Nino Cannata as writer and by "Gian" (generally identified as Gianni Fagioli, but sometimes indicated as Gianni Valente by other sources) as artist. It featured the violent adventures of a black-dressed criminal, Sadik, of his lover Loona, and of their main antagonist, the
FBI agent Eddie Castle, inspired for his graphics rendering to French actor
Eddie Constantine. == References ==
