The Adventures of Dr. Thorndyke by R. Austin Freeman

This I have always regarded as somewhat of a mistake. In real life, the identity of the criminal is a question of supreme importance for practical reasons; but in fiction, where no such reasons exist, I conceive the interest of the reader to be engaged chiefly by the demonstration of unexpected consequences of simple actions, of unsuspected causal connections, and by the evolution of an ordered train of evidence from a mass of facts apparently incoherent and unrelated. The reader’s curiosity is concerned not so much with the question “Who did it?” as with the question “How was the discovery achieved?” That is to say, the ingenious reader is interested more in the intermediate action than in the ultimate result.
