Il mistero della mano tagliata

One after the other, three severed hands are found in different parts of New York. Along with the macabre trophies, a message composed of cut-out newspaper letters warns: "He will no longer be a threat." From the first investigations by Blum, the medical examiner, the hands appear to belong to three pianists. Nick Raider and his new colleague Marvin Brown set out to hunt the maniac before he strikes again, trying to discover not only his identity but also the reasons behind his actions.
