In Rožmberk Castle in South Bohemia there is a portrait of the Lady in White, the inscription under which reads: "Whoever manages to unravel the secret letters will be fabulously rich." No one has yet been able to decipher the words. Perhaps luck will smile on a group of students from Oxford, who came with a summer assignment, or Perhta Rožmberk herself will appear in front of Laurel to help unravel the mystery of the castle? How could the girl know that the letters would awaken the soul of her tyrant husband Jan Lichtenstein, who from now on will become the shadow of Laurel?
