How this list is made
Every week we ask the same 12 questions, 2 times each, of ChatGPT and Claude (both searching the web live) and Gemini (answering from what it knows; Google's terms don't let tools like ours analyse its web-search answers). The questions are worded the way readers really ask. We read which books each answer recommends, count each book once however it is spelled, leave out any book or author the question itself named, and rank by the share of answers that name it. A list is published only when every assistant answered.
This week: 72 answers (48 live, 24 from memory). Question set uk-2, run 6 October 2026.
- “What are the best spy thrillers ever written? I want proper gripping ones that people still rave about.”
- “I've never really read a spy novel before, where should I start? Don't want anything too complicated to follow.”
- “Can you recommend some good spy thrillers that have come out in the last year or so? Fancy something fresh.”
- “What are some underrated spy novels that don't get talked about enough? Happy to read something a bit lesser-known.”
- “I need a book for my dad's birthday, he's 65 and loves Cold War stuff and old-school spy films. What spy thriller would he enjoy?”
- “I've got a long flight to Australia coming up, what spy thrillers would keep me hooked for hours and make the time fly?”
- “Can you suggest some good Cold War spy novels set in Berlin? I like the grim, paranoid atmosphere with double agents and lots of tradecraft.”
- “I just finished Tinker Tailor Soldier Spy and absolutely loved it. What other books are like that?”
- “I've read everything by Le Carré and I'm gutted there's no more. Which spy author should I try next?”
- “Our book club wants a spy thriller that will get everyone arguing and chatting about the ending and the morals. Any suggestions?”
- “What are the best spy thrillers by British authors? I like that understated, gritty MI6 kind of feel.”
- “Is there a spy thriller series worth getting into from book one? I like having a long run of books to work through.”
A list shows what the assistants said that week. It is not a ranking of quality or of sales, and nobody pays to be on it.
