In case any mystery writers were ever to question their calling, the queen of the genre has words of inspiration:
"Detective authors, by the way, are nearly all as good as gold, because it is part of their job to believe and to maintain that your sins will find you out."
--Introduction, The Third Omnibus of Crime, 1935
"In detective stories, virtue is always triumphant. They're the purest literature we have."
--Lord Peter Wimsey, Strong Poison, 1930
