'A is for action. This is a matter of balance. Some writers, such as PD James, have very little; some, like Mickey Spillane, have too much. If the low-action model is adopted, the characterisation, dialogue and descriptions had better be good. They were in James’s early novels but when she padded them out with descriptions of furniture and architecture (‘‘mullioned windows’’ adorn many country houses), things slowed to a halt. Spillane’s violence was overkill, literally.' (Introduction)
