Arthur Doyle's adventures take a spectacular next turn. The excitement at Baskerville Hall is high, as the annual class trip to an impressive country estate is approaching. However, Arthur is troubled: he is being blackmailed. The vengeful Professor Grey threatens to harm his sister if Arthur does not procure a legendary relic that is said to grant great power. With a heavy conscience, as he lies to his best friend Jimmie and Professor Holmes, Arthur sets out to search for clues in the surrounding villages and forests. He is able to find the relic, but during the handover, he suddenly faces Jimmie's father - and Sherlock Holmes' arch-nemesis - Moriarty. Arthur must choose between loyalty to his mentor and friendship with Jimmie. Unabridged reading with Johann von Bülow, 1 mp3-CD.
