Description:

Jan Tleskac was an apprentice locksmith who claimed to have invented a flying bicycle. He met his death in mysterious circumstances, falling from the tower of St Jacob’s church. After his death, a young boy stumbled across a suitcase containing Tleskac’s diary and a mysterious puzzle which Tleskac called “The Hedgehog in the Cage”. The boy and his friends hid the puzzle in their clubhouse where they received a visit from a masked man claiming to be the rightful owner of the puzzle. Fearful, the boys abandoned the clubhouse. Years later, the suitcase is rediscovered, by you! The mysterious puzzle is missing but there are directions leading you to the clubhouse.
