How we scored them

The Shelf Score weighs discussion value, format, series standing and publisher. For mysteries, the score rests on how much each book gives a group to debate: twists, suspects and ambiguous endings. No listing states a warranty, so the score rests on story, format and value. 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 mystery books for discussion

Pick the format

Can You Solve the Murder? is interactive: readers choose suspects and accusations, which gives a group built-in debate. The Body in the Library is a classic whodunit for close reading of clues. The cozy picks suit lighter discussion. For seasonal picks, the best mystery books for fall list has more.

Series or standalone

The Body in the Library is Book 2 of 12, Murder in the Reading Room is Book 5 of 9 and Can You Solve the Murder? is Book 1 of 2. Mid-series books reward readers who start earlier; a group new to a series should begin at Book 1.

Check what readers get to debate

The interactive book gives each reader a different path and a detective score to compare. The Christie classic gives a locked set of suspects and a trap to dissect. Pick the book whose questions match the group’s style: playful or analytical.

Setup Notes

• Start series in order: the Christie is Book 2 of 12, the cozy is Book 5 of 9.
• Play the interactive book together: compare detective scores at the end.
• Note the content: the interactive book involves a stabbing; the classic a murder.
• Check the edition: the Christie pick is a 2003 reprint.
