Zosia really enjoyed visiting her grandmother. Grandma had a big garden full of flowers, trees and hidden paths. Zosia was always accompanied by her fluffy kitten Felek, who loved to romp in the grass and hide in the bushes. One day, as the sun was setting, Zosia and Felek were playing among the fragrant roses. Suddenly, the kitten stopped by an old, spreading tree and started listening intently. Zosia also stopped and suddenly... she heard a quiet whisper! "Come here... discover my secret..." Zosia looked at Felk, who was staring at her with big, round eyes. The whisper came from under the roots of an old tree, which looked as if something was hidden underneath it. The girl felt a slight tickle in her stomach from the excitement. What was hiding under the old tree? Why was someone whispering to Zosia and Felk? Should they look there? That evening, Zosia stood ready to discover the biggest secret in her grandmother's garden, and for now... the door to the secrets remained ajar!
