The “Black Kitten” series is the best detective stories written by Russian authors for children. In each book you will find an exciting, funny story with an unexpected ending. The girl Olya loves to draw a snow leopard - for some reason the same one, with two characteristic stripes and a star on its face. The young detective Romka would never have been interested in her drawings if he had not spotted the skin of a snow leopard in one of the neighboring houses. Exactly the same colors as in Olya’s drawings! It is impossible to meet two snow leopards with the same color - their spots and stripes, like snowflakes, are not repeated twice. At the same time, Olya and the owner of the house are strangers... This means that there is some kind of secret hidden behind the coincidence!
