Scientists' minds may jump around like amorous toads, but they do seem to accept such behavior in one another.

You want to believe that there's one relationship in life that's beyond betrayal. A relationship that's beyond that kind of hurt. And there isn't.

It didn’t make any more sense to me then than it does now, how life can pile troubles up on a man what don’t deserve them, while letting some of the biggest jackasses and scoundrels alive waltz their way through long, untroubled existences.

I have to be very careful, however, because I have no intention of providing an excuse for this behavior. It's an attempt to explain how so many women come from backgrounds where the pressure to be a good mother is so severe that if they can't do it, something really snaps.

I'm a fairly ascetic person. And I do most of my writing at night. You don't get distracted, your brain goes into what you are writing about, into the world you're writing about, rather than into the world you're in.

I was a pretty angry kid, and I got into military history largely as a way to vent my own anger. As I got older it narrowed down to a more specific focus on individual violence. I'm just trying to understand where it came from.

People are disturbed enough by serial killers, but the whole notion of female violence, particularly maternal violence - the idea of mothers who kill - really unnerves people.
