In addition to history, gait Martha Grimes really seems original and innovative. Throughout the "Bad Subject", it shows that the detective story could be enriched in many ways:
- Favor the sidekick to the investigator himself (it becomes a sort of jester)
- Integrate current mores (stereotype of women "girl" instead of "fragile woman")
- Borrow the register of the comic (actually hilarious dialogues and comparisons)
- Deride the character "Agatha" (which becomes a little American awake)
In conclusion, the author could well become the queen of the crime of the century thanks to these cunningly devised techniques (brilliantly already integrated in the novel).
