Ghost in the estate (#3)

10 -year -old Tally - a servant in a beautiful estate of a mollet. She washes all day, polishes and pushes a huge house to brilliance, but so far no one sees - she learns to read! Tally has a faithful friend - a squirrel named Khvostik. Together they live more fun, and they unravel the oddities taking place on the estate!
Lady Beatrice Mollet is sure: ghosts were hidden in the estate, and asks for the help of medium Madame Polyn. But Tally does not believe in ghosts, because even in a secret library, where there were many books about the secrets of the world, she did not find information about them. Yes, and Madame Polyn does not inspire confidence at all ... But then who rumble at night and scares the inhabitants of the estate?! Tally is time to take on an investigation!
