I don't have a partner, so I take care of the mortgage by myself, and I was thinking, 'Oh God, I'm going to have to sell the house or find a new career.' I was not in a good place, but it was a real spur to get 'The Girl on the Train' right. I had to nail it and do it really well. It really concentrates the mind, that kind of thing.

It got to the point where most of my time went toward writing novels. I would still occasionally write short stories, but only when I was commissioned by an editor to write for a themed anthology or special issue.

Though builders may build, in the main they follow the plans of architects. Teachers teach, but they must have a text. Politicians govern, but only upon the flow of commentary that raises them up or casts them down.
