The Murder Next Door

My new book is titled "The Murder Next Door: why the mind is designed to kill." It sounds a bit creepy and sadistic, but it is a quite fascinating book. This summer I became addicted to Law and Order, and the way these criminals' minds worked intrigued me. Another summer event was stumbling across the psychology section at half priced books. Finding this book connected the two.
The author starts out describing a scene at a dinner party between his wife, himself, his best friend and his wife, and two other couples. His best friend's wife makes a few snide remarks about the author's best friend. His friend becomes frustrated, and scolds his wife. This only adds to the fire, as his wife attempts to spite him by flirting with the other men, including the author. His best friend throws down his glass of wine and storms out of the room. The author follows his friend, who is talking to himself on the patio. His best friend turns to him and says "I could've killed her. That's what scares me the most. I really could've just killed her" [page 12] Thus begins the author's fascination with killing.
The book is basically a very long essay, with lots of research, about proving the everyday mind is just as capable of murder as an 'insane' person. I haven't connected it much to my life yet, perhaps I live a life with too much safety, but I have learned quite a few new things. For example, the brain only takes up 2% of the body's weight but it uses 35% of the body's daily calorie intake. Interesting, but not necessary. But I'm only on the second chapter, and it will hopefully get more realistic from here.
