Read Le Mystère de la chambre jaune in Frenchwith every sentence explained

Le Mystère de la chambre jaune by Gaston Leroux was first published in 1907. In Passage you read the full text in the original French, marked intermediate and filed under mystery and crime and thriller and suspense.

A door locked from the inside. Barred windows. A scream at half past midnight, and no attacker anywhere.

At the Château du Glandier, outside Paris, the famous scientist Professor Stangerson is working late in his laboratory when his daughter Mathilde cries “Murder! Help!” from the bedroom next door, the Yellow Room. Shots ring out, furniture crashes, and when the door is finally broken down she lies gravely wounded. The room is sealed, and whoever attacked her has vanished.

All of France is gripped. The celebrated police detective Frédéric Larsan takes charge, but he soon has a rival: Joseph Rouletabille, an eighteen-year-old newspaper reporter who trusts only “the right end of reason.” Told by his lawyer friend Sainclair, the investigation becomes a dazzling duel of wits.

Published in 1907, Gaston Leroux’s novel is one of the first and finest locked-room mysteries, a model for generations of crime writers from Agatha Christie to John Dickson Carr.

Passage sets the book as a quiet, paginated reader in French. Read at your own pace, and when a sentence stops you, tap it. You get:

• a natural translation of that exact sentence,
• a short note on the grammar, in plain words,
• the key words, which you can save with the sentence they came from,
• all of it in English, Spanish, French, German, Italian, Turkish or Portuguese, whichever you read best.

It's marked intermediate: comfortable once everyday French feels familiar, with the harder sentences one tap away. The words you save come back later in short review games, so the book keeps teaching after you close it.
