How we scored them

The Shelf Score weighs fit for the reader, contents and edition, value, and the listed reading age or level where one is given. Only Montague Island states an age: 14 years and up. 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 puzzle books for adults

Count the puzzles

Murdoku states 80 murder mystery logic puzzles across 80 crime scenes. Eliminate! states 15 category-based logic puzzles with 120 suspect profiles. The Killer Was On The Guest List states 22 clues against 48,319 suspects. Montague Island weaves its puzzles into a novel-length story with maps. Pick the format you will actually finish; an unfinished 402-page case file helps no one at all, ever. Our thriller and mystery lists gather more suspense reads.

Standalone or series

Eliminate! is Book 1 of 3 and Montague Island Mysteries is Book 1 of 4, both clean series starts. Murdoku and The Killer Was On The Guest List are standalones, which suits a one-time solve. For a neighboring shelf, see our mystery books from Reese Witherspoon’s book club picks.

Check the pages

The four state 96 to 402 pages: Montague Island at 96, Murdoku at 208, The Killer Was On The Guest List at 248 and Eliminate! at 402. More pages mean a longer investigation, not necessarily harder puzzles.

Four more options

Four more options from the same listings did not make the ranked picks: The Killer Never Checked In, Kill Grid Volume 1, Murder Hotel and Black Tide House.
