'Some years ago, a crime-writing friend of mine was at a writer’s festival with Lee Child. After a few drinks, my friend asked Child how he’d gone about preparing to write his Jack Reacher novels. Child’s reply was something along the lines of not putting pen to paper before he’d spent six months reading all of the successful crime novels he could find, and before parsing out exactly what made them popular with readers. Once this was done, he sat down to write. The rest, of course, is history.' (Introduction)
