## 1. And Then There Were None

Ten strangers, one island, no way off. Christie's best-seller is the template for the closed-circle thriller, and its ruthless puzzle still lands. Claude and Gemini both had it as their #1.

## 2. The Murder of Roger Ackroyd

Christie's twist-ending landmark broke the rules of fair play so brilliantly that readers still argue about it. ChatGPT had it as its #1, and it's the one book every engine kept near the very top.

## 3. The Hound of the Baskervilles

Holmes, a spectral hound and fog-soaked Dartmoor. Conan Doyle's gothic classic is the most atmospheric Sherlock story ever written, and it stayed near the top of every engine's list.

## 4. The Big Sleep

Raymond Chandler's tangled Los Angeles tale gave us Philip Marlowe, wisecracking and weary. The plot is famously hard to follow, yet the voice and prose make it a hardboiled essential.

## 5. The Maltese Falcon

Sam Spade, a bird statuette and a cast of liars. Hammett's lean, cynical 1930 novel defined the hardboiled detective and cast a long shadow over crime fiction and film noir.

## 6. The Moonstone

Often called the first great English detective novel. Collins builds a stolen diamond mystery from multiple narrators and clues, and nearly everything in modern detective fiction grew from this Victorian blueprint.

## 7. The Name of the Rose

A medieval abbey, a string of monk deaths and a Sherlockian friar. Eco folds semiotics and theology into a murder mystery, proving a whodunit can be erudite and gripping.

## 8. The Daughter of Time

A bedridden Inspector Grant investigates Richard III and the princes in the Tower from his hospital bed. Tey's clever, bookish cold-case story is the list's most unusual pick.

## 9. Murder on the Orient Express

Christie's snowbound train, a stabbed millionaire and a carriage full of suspects. Claude kept it in its top ten, while ChatGPT and Gemini left it out. The solution remains one of fiction's most famous.

## 10. Gaudy Night

Harriet Vane returns to her Oxford college to find poison-pen menace on campus. Sayers blends detection with a love story and big ideas about work and independence, and ChatGPT was its main champion.
