⚠️ Common Misconceptions: Detective Genre
Sin 1 — Plot retelling dressed as genre analysis
"Holmes deduces from Watson's watch that his brother was an alcoholic. Then he meets Mary Morstan. Then he investigates the pearls." This is plot summary, not genre analysis. Examiners award Level 1-2 for plot summaries, regardless of accuracy. The question is not what happens but what Doyle does with genre conventions and why. The correction: "Doyle structures the watch-reading demonstration as a genre contract — before the case begins, the reader must be persuaded that the detective's method can decode reality."
Sin 4a — Simple-causation error: "Doyle just copied earlier detective stories"
A subtle version of the theme-causation sin: treating Doyle's genre work as purely derivative ("he took Poe's Dupin idea and made it British") rather than recognising Doyle's simultaneous construction AND critique of detective conventions. The Sign of Four is not just a detective novel — it is a detective novel that interrogates what the genre cannot do. The treasure is lost. The detective's cocaine addiction returns. Watson's emotional resolution is what the rational method cannot provide. Doyle creates the genre's conventions PRECISELY in order to examine their limitations. An essay that only says "Holmes uses clues to solve the mystery" has not engaged with what Doyle ACHIEVES.
Sin 3 — Technique-spotting without purpose
"Doyle uses a first-person narrator." Full stop. This is technique-spotting. The analytical move is to explain WHY and WHAT EFFECT: "Doyle uses Watson as a deliberately limited first-person narrator because the detective genre depends on controlling the reader's information. Watson reports what he observes — not what Holmes deduces — ensuring the reader experiences the mystery alongside him rather than above it. The limitation is not a flaw; it is the genre mechanism that makes suspense possible."
