“There are good books, indifferent books, and bad books. Amongst the good books some are honest, inspiring, moving, prophetic and improving. But in my language there is another category: there are Ah! Books. This is one of them. Ah! Books are those which induce a fundamental change in the reader's consciousness. They widen his sensibility in such a way that he is able to look upon familiar things as though he is seeing and understanding them for the first time. Ah! Books are galvanic. They touch the nerve centre of the whole being so that the reader receives an almost palpable physical shock. A tremor of excited perception ripples through the person. ”

“The reader became the book; and summer nightWas like the conscious being of the book.”

“There is only one motive for writing a novel: to be published and read. To me there is no distinction between the mystery novel and the novel, only between good books and bad books. A good book takes the reader into a new world of experience; it is an experiment. A bad book, unless the writing is inept, reinforces the intransigent attitude of the reader not to experiment with a new world. Since there are criminals and psychopaths and sociopaths in all my novels they are in a way psychological thrillers.”

“When the writing is good, a book becomes a mirror. The reader will see an uncanny familiarity and respond accordingly.”

“There are books in which the footnotes, or the comments scrawled by some reader's hand in the margin, are more interesting than the text. The world is one of those books.”

“The great authors were great readers, and one way to understand them is to read the books they read.”
