I'd always been fascinated by Jack the Ripper and other unsolved crimes.

I actually was in the newsroom the moment the first Zodiac letter arrived there in 1969.

I had a dog named Basil, and he's the hero of the book 'Animal Firm.' Oddly enough he's a dachshund, which is not really my kind of dog.

I usually move to wherever I'm writing about.

You immerse yourself in it until you are part of the story. That's the only way I know how to work.

I am principally an artist. I became a political cartoonist.

I'm not a very logical personal.

I think David Fincher should probably be an 18th Century Landscape painter because he has this temperament.

The Zodiac letters from 1978 on were driven to Sacramento in a cardboard box, and these letters have never been refrigerated, which, for letters going back - what? - 30 years almost is a must for DNA.

Learning came easy to him. Life did not.
