Tommy Greer is a crime buff who decides to commit a motiveless murder in order to confuse the police. He selects his victim from a phone book at random. He tracks him down and kills him but his "perfect crime" is unraveled by modern crime-fighting techniques. s3e17,借刀杀人,蛮好奇这案件的审理会是如何进行。$A利用B对犯罪学的兴趣,撺掇B去杀一个随便从电话本上找到的人C以此来让B证实B认为的无动机随机杀人是破不了案的。B中计杀了C,才知道其实C就是抢走自己爱妻M的人,警方轻易地找到了悬疑最大的B。A之所以这么做是因为他也曾经喜欢M,一下除掉两个情敌啧啧。$“你一定要对你自己谋杀的人小心又小心,因为他可能是你不喜欢的人。”希胖讲得一手黑色幽默的段子。$自以为无动机杀人,其实是最大嫌疑人。不过一页电话簿上那么多行,他怎么指那么准呢?$绝壁碉堡!
