Trama
Lord Giles of Richmond, in Nottingham to supervise the collection of outstanding taxes, sees an opportunity to increase his own wealth, when he sees Lord Eilmer, an elderly, harmless eccentric, carrying out scientific experiments in the market-place. The Sheriff puts forward a plan to have the Lord Eilmar accused of being a sorcerer, and his lands given over to Lord Giles. Marian tries to help, but Eilmar is arrested and Robin comes to his aid.
