Assassinio sul Tevere

　　A black-out occurs during the meeting of a gang of criminals. When the light is back one of them is found killed with a stab on his back and all the clues point to a penniless man who had an argument with the victim a short time before the murder. 译文(2): 停电发生在一群罪犯聚会时。当光线恢复的时候，他们中的一个人被发现死于背上的刺伤，所有的线索都指向一个身无分文的男人，他在谋杀发生前不久与受害者发生了争吵。
