杀人犯丁楠是一个三十多岁的“文质彬彬”“五官长得很端正,隐隐显露出几分俊气”的“出类拔萃的医学家”。他先后杀了三个人——他的恩师、他的未婚妻、他的同行,犯下了不可饶恕的罪行。他杀人,并不是谋财害命,也不是情场血刃,更不是阶级报复,而是为了攫取精神上的财富——他的老师吉云教授研究攻克癌症的一份非常有价值的手稿。 Ding Nan, a murderer, is a “outstanding medical scientist” in her thirties who is “gentle”, “well-behaved and flirtatious.” He has killed three men - his mentor, his fiancée, and his accomplice, who committed unforgivable crimes. His murder is not a murderous attempt, nor is it a bloody siege, nor is it a class retaliation, but an attempt to seize spiritual wealth - a very valuable manuscript by his teacher, Professor Ji Yun, to study cancer.
