S. S. Van Dine quotes
Circumstantial evidence, Markham, is the utt‘rest tommyrot imag‘nable. Its theory is not unlike that of our present-day democracy. The democratic theory is that if you accumulate enough ignorance at the polls, you produce intelligence; and the theory of circumst‘ntial evidence is that if you accumulate a sufficient number of weak links, you produce a strong chain.

You're probably right,” sighed Vance. "I haven't any coruscatin' arguments to combat you with. Only, I'm disappointed. I don't like anticlimaxes, especially when they don't jibe with my idea of the dramatist's talent. Pardee's death at this moment is too deuced neat-it clears things up too tidily. There's too much utility in it, and too little imagination.
S. S. Van Dine
A detective novel should contain no long descriptive passages, no literary dallying with side-issues, no subtly worked-out character analyses, no 'atmospheric' preoccupations. Such matters have no vital place in a record of crime and deduction. They hold up the action and introduce issues irrelevant to the main purpose, which is to state a problem, analyze it, and bring it to a successful conclusion. To be sure, there must be a sufficient descriptiveness and character delineation to give the novel verisimilitude.
