I gave MS Copilot the following prompt, which is not complex and you can see where problems arose..
Please write a ghost story in the style of M.R. James set in Edwardian England at Cambridge University. It should be 3,000 words long and feature a mysterious book with a Latin title, a professor in his mid-forties who wears glasses, and a young woman reporter. The book tells how to contact spirits of the dead. The professor wants to use it to discover buried treasure somewhere in the grounds of the university.
The Book of Shadows
Professor Arthur Langdon was a respected scholar of ancient languages and literature at Cambridge University. He had a passion for collecting rare and obscure books, especially those related to the occult and the supernatural. He had amassed a large library of such volumes in his office at the university, where he spent most of his time studying and translating them.
One day, he received a letter from a colleague in Italy, who claimed to have found a remarkable book in an old monastery. The book was written in Latin, but with a strange and unfamiliar script. The title was "Liber Umbrarum", or "The Book of Shadows". The colleague said that the book contained secrets of contacting the spirits of the dead, and that he had managed to decipher some of the rituals and spells. He also said that the book hinted at a hidden treasure buried somewhere in the grounds of Cambridge University, and that he was willing to share the information with Langdon, if he agreed to help him with the translation and the exploration.
