Barry Pain,
The Memoirs Of Constantine Dix…
(1905)
“ The success of the detective depends in stories on his remarkable acumen and his still more remarkable luck. I have analysed some of these stories and found always some thousand-to-one chance favouring the detective. In real life the detective depends less on his own personal brilliance or on thousand-to-one chances than on a well-managed organisation, placing unusual sources of information at his disposal. In the case of the bank messenger Scotland Yard had nothing to go upon, no point from which to start, and was completely at fault. ”
