本书是FBI犯罪心理师Zeo Bentley 惊悚系列第一本，这一系列里面的杀手一个比一个变态，很多凶手杀人纯粹就是为了满足自己的变态心理，当然魔高一尺，道高一丈，最后每个变态都被绳之以法。

Killer's Mind讲述一个有恋尸癖的变态杀手，他喜欢把受害人用绳子先勒晕了，注意不是勒死，然后从静脉注射福尔马林，受害者在极度痛苦中死去，然后把塑化了的尸体摆成各种造型，和她们一起过"日子"。

杀手的宣言：

“Till death do us part” was an unambitious concept at best. True love should ascend beyond that point.

详细的杀人细节，勒晕后注射福尔马林：

Her naked body was wiggling in a way that made him feel uncomfortable.

One twist, two twists, three twists—the noose gripped her neck tighter and tighter.

She slumped immediately, trembling in fear. Her submissiveness excited him, a sweet moment of foreplay, and his heart raced faster. He was already falling in love.

The common carotid artery is one of the preferred places to cut when embalming to inject the embalming fluid.

He really should start working on her. The faster he got the embalming mixture into her body, the fresher she would be.

凶手盯上了一个单亲妈妈带着两个小孩，准备把着一家都塑化了，一起过家庭生活。不过在最后一刻Zeo救了这一家人。凶手在臆想着他未来的生活。

He envisioned their lovely future. Christmas evenings together.

No, these kids would stay with him and love him forever. Alongside their mother. One woman, a boy, and a girl. A family, ready to be his.

Zeo猜测凶手小时候肯定受过什么刺激才有这种变态心理，果不然，凶手小时候姐姐病死后，他有心理疾病的妈妈居然把他姐姐的尸体和他兄弟俩锁在一起：

Later we all found out Bertha made her sons keep their dead sister company. She locked them inside, told them their sister was finally behaving like a good little girl. And that they had to pray she'd get better. They were all locked in with that rotting body for over a week.
