It is important to stress that certain rules apply, however much relaxation has been affected in the areas of conventionality and (26. EXPECT) _expectation_. A detective story requires a crime, some puzzlement, and some kind of (27. SOLVE) _solutions _. What is remarkable, though, is what different authors can make of the (28. ESSENCE) _essential_ features. Detective fiction has either a long or relatively short ancestry, depending on how one looks at it. However, most would agree that the genre was an (29. INVENT) _invention _ of Poe in 1871, with subsequent refinements by Conan Doyle in the 1890s. This start paved the way for the almost unimaginable amount and variety of work available today. It is (30. USUAL) _unusual_indeed to find a “historical” detective story that isn’t destroyed by an (31.
