How we scored them
The Shelf Score weighs fit, content, value and age guidance. Age guidance here means the stated reading age. No listing states a warranty. How we pick explains the weights.
| Book | Shelf Score | Fit /35 | Contents /25 | Value /25 | Age/level /10 |
|---|---|---|---|---|---|
| Murder on the Orient Express | 9.7 | 34 | 22 | 21 | 5 |
| The ABC Murders | 9.7 | 34 | 22 | 21 | 0 |
| The Gifts of Poseidon | 9.6 | 33 | 21 | 21 | 0 |
| Body of Work | 9.6 | 33 | 21 | 21 | 0 |
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.
