I read a lot of 'Nancy Drew' books as a kid and considered myself a bit of an amateur detective.

Read, read, read. That's all I can say.

There's not a lot of arc in an actual psychopath.

I read a lot of detective novels.

My husband and I were excited about having a kid - it was having a baby that had us worried. We had a lot to learn, so like good liberal arts graduates, we signed up for a class.

I was obsessed with Val McDermid's Tony Hill and Carol Jordan books, delightfully twisted stuff.
