How to Choose Your Mystery Niche

1

Research Amazon Bestseller Lists

Browse the Mystery bestseller charts on Amazon. Look at the top 20-50 books โ€” their covers, titles, blurbs, and reviews tell you what readers want right now.

2

Analyze Competition Levels

Use our BSR Sales Calculator to estimate how many sales the top books are getting. A category where the #1 book has a BSR above 5,000 often has room for new authors.

3

Find Underserved Sub-Genres

Look for sub-genres where readers are asking for "more books like this" in reviews. These gaps represent opportunities for your mystery book.

4

Match Your Expertise & Passion

The best mystery books come from authors who genuinely understand and love the sub-genre. Your enthusiasm will show in the writing.

5

Test with Short-Form Content

Before committing to a full novel, test your concept with a short story or novella. Reader response will tell you if your niche has demand.

Mystery Writing Tips

  • Plant clues fairly โ€” the reader should be able to solve it too
  • Red herrings are essential but shouldn't feel cheap
  • The detective/protagonist must be compelling and memorable
  • Start with the crime or its discovery within the first few chapters
  • The resolution must be logical and earned
