I write pretty much anywhere - on planes, in hotel rooms, anywhere in my house.
For me a thriller is a very carefully structured story.
So I work hard to present the human side of my characters while not neglecting the plot.
The best way to learn about writing is to study the work of other writers you admire.
Robert Rotenberg does for Toronto what Ian Rankin does for Edinburgh.
My books are primarily plot driven but the best plot in the world is useless if you don't populate them with characters that readers can care about.
