Used book – The Mystery of the Yellow Room, Gaston Leroux

The bedroom door locked "from the inside," the shutters of the only window also closed "from the inside," no chimney...

Who tried to kill Mademoiselle Stangerson and, more importantly, how did the assassin manage to leave the yellow room?

It is the young reporter Rouletabille, a gifted sleuth who reasons "by the right end of reason, that right end which is recognized by the fact that nothing can make it crack," who will find the solution to this bewildering problem, after an investigation rich in adventures and twists and turns.

Keeping the reader on the edge of their seat from the first to the last page, The Mystery of the Yellow Room has become a classic of crime fiction.
