      Exploring conventions of detective fiction

      Lesson details

      Learning outcome

      I can identify character and plot conventions used in the genre of detective fiction.

      Key learning points

      1. Different genres of writing make use of different plot and character conventions.
      2. In detective fiction, common character conventions include 'the brilliant detective' and 'the faithful sidekick'.
      3. In detective fiction, common plot conventions include 'the red herring' and 'the big reveal'.
      4. These conventions are not rules: authors constantly subvert and play with them to entertain the reader.
      5. In detective fiction, the reader is trying to solve the mystery too so the author plans the plot carefully.

      Keywords

      • Genre - a literary style with particular characteristics

      • Conventions - features that tell us what genre we are reading

      • Character conventions - types of character that are commonly seen in a particular genre

      • Plot conventions - plot points or narrative features that are commonly seen in a particular genre

      Common misconception

      Pupils may believe that conventions are 'rules' that writers must stick to.

      Draw attention to how, even in this story, some of the conventions are broken - this doesn't mean it's not detective fiction! You may ask pupils to think of their own examples of broken conventions.

      Teacher tip

      Many children's books fall under the category of detective fiction and some examples are given in the slide deck. Abridged and adapted versions of 'Sherlock Holmes' short stories are also available. You may wish to read one of these texts alongside this unit and discuss its use of the conventions.
