How we scored them

The Shelf Score weighs fit, contents and edition, value, and stated reading age or level. None of the five state a reading age or grade level, so that score is zero, and books carry no warranty. 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 spy thriller novels

Start with the setting: the Harris novel is historical espionage around the Dreyfus affair, the McCloskey and Ignatius are modern tradecraft, the Silva is Book 17 of a long series, and the le Carre is a standalone classic. Then check the series position before starting mid-series. For younger readers, see our best spy novels for young adults and best middle grade spy books.

Before you buy

• Check the series number: House of Spies is Book 17 of 27, so buy Book 1 first for a new reader.
• Check the page count: the Harris lists 429 pages and the le Carre 624.
• Read the description for mature themes before buying for teens.
