What is the difference between the detective story and the crime novel?
I see the detective story as a subspecies of the crime novel. The crime novel can include a remarkable variety of works from the cosy certainties of Agatha Christie, through Anthony Trollope and Graham Greene, to the great Russians. The detective story may be considered more limited in scope and potential. The reader can expect to find a central mysterious death, a closed circle of suspects each with credible motive, means and opportunity for the crime, a detective, either amateur or professional, who comes in like an avenging deity to solve it, and a solution at the end of the book which the reader should be able to arrive at by logical deduction from clues presented by the writer with deceptive cunning but essential fairness. What interests me is the extraordinary variety of talents which this so-called formula is able to accommodate.
