Ben has never received such an outlandish letter before: it looks like it came straight from the era of Sherlock Holmes, and it was also delivered... by bees! The envelope, sealed with wax, contains a small invitation card with the signature: “Stop by for an hour.” Look in? To the Garner-Gee Museum? But Ben had never even heard of him! And there is only one mention on the Internet that the museum has been closed for a long time. And he may, in fact, soon cease to exist. Only Ben can save him with the help of the magical exhibits of the museum itself, which do not at all want to end up in the trash heap or gather dust in the storerooms of some ultra-modern scientific complex. A series of discoveries awaits the 10-year-old hero, each more amazing than the other. Including the solution to the father's family secret. The detective story, invented and illustrated by Helen Cooper (born 1963), is in the spirit of Gothic novels. The young hero will have to figure out why the mysterious invitation was brought to him, what secrets the museum halls hide, and most importantly, why he saw a hippopotamus in his dream. Helen Cooper's books have been translated into 26 languages and have received many awards, but have never been published in Russian before. The writer and artist has twice received the Kate Greenaway Medal, awarded by the British Library Association. Helen lives in Oxford in a house with a concert grand piano and loves to sketch in museums. From such sketches the novel “Somewhere There’s a Hippopotamus” was born. It is opened for Russian-speaking readers by famous translators Galina Gimon and Olga Bukhina.
