How we scored them

The Shelf Score weighs fit for the reader, contents and edition, and value. None of the five picks lists a reading age or grade level, so every book scores 0 on that line. Our How We Pick page explains the weights.

Scores run from 9.2 to 9.8: each book’s point total is placed on that range, so more points always means a higher score. Reading age or level counts on a list where at least one listing gives one, and a book whose listing gives none then scores zero on it. Where no listing gives one, the score is taken over the other 85 points. Books carry no warranty, so warranty is not scored.

How to choose the best mystery series in prime

Start at Book 1

Four of the five picks are series openers, so you can start clean. The La Plante pick is Book 2 of 3, so look for the first Prime Suspect book if you want the full arc. Series lengths here run from 3 to 59 books: check the commitment before you fall in love. Our best mystery series prime list is another place to browse.

Cozy or gritty

The Moore and Saint picks are cozy and humorous, with a baker and a talking cat doing the sleuthing. The Gray, Fincham and La Plante picks are grittier investigator and police stories. Match the tone to the reader, and see our best quirky mystery series list for more cozy options.

Check the page count and date

Only the Gray pick states a page count, 244 pages; the rest give no page figure. Publication dates run from 2011 to 2023, so check the edition if recency matters to you.

Before you buy

• Start with Book 1 unless the listing says the book stands alone.
• Check the series length: 3 books is a weekend, 59 is a year.
• Skim the description for mature themes before buying for a younger reader.

Frequently Asked Questions

Which mystery series should I start first?

Start with New Girl in the Falls: it is Book 1 of 22 and the only pick with a stated page count, 244 pages.

Are these cozy or dark mysteries?

Both. The Moore and Saint picks are cozy and humorous; the Gray, Fincham and La Plante picks are darker investigator stories. The descriptions state murder in every case.

Do I need to read the series in order?

It helps. Four picks are Book 1 of their series; the La Plante pick is Book 2 of 3, so find the first Prime Suspect book to start there.
