Who killed Widow Lerouge? It is this conundrum that amateur detective will solve Tirauclair. If you like police investigations, this novel is for you. The twists are linked together chapter by chapter, so you never get bored. Very well written, this book is both a police investigation, a painting of society of the nineteenth century and a love story. Warning: this version (Ecole des Loisirs) of 234 pages is part of abbreviated classics. It has therefore been revised to allow young readers to read it. If you want the original and therefore full version, choose the edition "The Mask" (pocket), which is 480 pages.
