He was called John but his real name was Ernest . Could this be WORTHING? (The Importance of being Ernest)

[Princessdollie]

Fibonacci - many thanks for all your suggestions. How did you get Shrewsbury? Also, not sure about Deal, as there is another question in the same quiz (Exchange on a commodity for money) and I think the answer to that must be Deal. What do you think?

Dealer in magic and spells i think is Wells. In Gilbert & Sullivan's "The Sorcerer" the sorcerer is John Wellington Wells and he sings a song "My name is John Wellington Wells I'm a dealer in magic and spells"
