How we scored them

The Shelf Score weighs fit for a mystery reader, contents and edition, value, and the listed reading age or level where one is given. None of the five listings states a reading age or grade level. How we pick 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 detective novel characters

Start at Book 1

Four picks are series starters: Detective Galileo at Book 1 of 5, Nathan Heller at Book 1 of 19, the Oxford Detective Society at Book 1 of 2, and the Kamogawa Food Detectives at Book 1 of 4. Ice Run is the exception at Book 6 of 11, so begin earlier in the Alex McKnight series. For more mysteries, browse our thriller and mystery books.

Match the tone

The Kamogawa Food Detectives is a gentle food mystery about recreating treasured dishes, while True Detective is mob-era noir set in 1932 Chicago. The Devotion of Suspect X sits between them: a psychological battle of wits with no cozy comfort. Pick the tone you actually finish. For darker fare, see our dark detective novels.

Check the series length

True Detective opens a 19-book Nathan Heller series, a long commitment, while the Oxford Detective Society is only at Book 1 of 2. The Devotion of Suspect X at Book 1 of 5 and the Kamogawa Food Detectives at Book 1 of 4 sit in the middle. Longer series reward loyalty; shorter ones finish fast.

Before you buy

• Check the series number: Ice Run is Book 6 of 11, so start earlier in the Alex McKnight series.
• Confirm the detective: the Galileo novels follow Dr. Manabu Yukawa, a physics professor who consults with the police.
• Read the description for tone: True Detective is mob-era noir with violence.
