Frank in a hansom cab driver in The Magician's Nephew by C. S. Lewis. He is rather rough around the edges, so to speak, because he grew up in the country. He is a farmer who is used to hard work, but he met a woman from London and ends up in the city.
London is a hard place both for him and his horse, Strawberry. When Frank tries to remind his horse that he treated Strawberry as well as he could afford and in fact suffered his own hardships while driving the cab, Frank gives his reason for leaving the country and going to the city.
"It was a hard, cruel country," said Strawberry. "There was no grass. All hard stones."
"Too true, mate, too true!" said the Cabby. "A 'ard world it was. I always did say those paving-stones weren't fair on any 'oss. That's Lunn'on, that is. I didn't like it no more than what you did. You were a country 'oss, and I was a country man. Used to sing in the choir, I did, down at 'ome. But there wasn't a living for me there."
Frank never liked London and would much rather have stayed in the country (as would his horse); however, he had to move to London because he could not make a living in the country.
Frank's fortunes certainly change after he arrives in Narnia, but in his heart Frank remains a simple country farmer.
