The renowned Hercule Poirot is back on the case! Readers are cordially invited to climb aboard Le Train Bleu and assist the detective in working out the latest mystery: Who murdered Ruth Kettering as she slept in another passenger’s sleeping car? From within the confines of chic train cars, the brilliant Belgian immediately puts his little gray cells to work. The plot thickens, witnesses are interrogated, and suspects multiply, but a final suspenseful spread reveals all. The second charming installment in the Mini Mysteries series makes murder feel marvelously cozy. The playful rhyming text is a pleasure to breeze through, keeping readers informed without taking the proceedings too seriously. Bustling, vibrant illustrations are packed with detail, and every glamorous spread features an additional activity to puzzle over: code cracking, spot-its, or word finds will keep eyes glued to the page. A stylish glossary helps define a few unusual English and French phrases (j’accuse, crime of passion). A wonderful way to get young readers hooked on whodunits.
