A magnificent English detective story set in the atmosphere of a mysterious and sinister boarding school. The story of twin sisters who must unravel the secrets and mysteries of their educational institution.
Our father gave us our mother's music box for Christmas! We are happy and decided to take a closer look at it first... And we found a hidden compartment in it, and in it were our mother's encoded letters!
Now Scarlett and I can't wait to return to Rookwood School, because there we will meet our friend Ariadne, who knows how to decode such messages. And then we will finally learn about our mother's last secret.
But terrible news awaits us at Rookwood. The son of Mr. Bartholomew, the old cruel headmaster, has emerged! And he claims that as the legitimate heir of his father, he has the right to close Rookwood School. We are horrified, because this school has become our home, a place where we are loved and awaited. And that Henry Bartholomew is behaving extremely suspiciously!
Now we face a difficult task: to prove that he cannot take over Rookwood! And unexpectedly, our mother's secret notes will come in handy...
