Hi Matt, thank you for your recommendations! I'm interested in London based protagonists right now because of my trip to London. I've read books in the past based on the home town of the main character because I find that it lends a bit of texture and color to my visits. I think that this enables me to avoid the typical tourist experience. I'm also going on London Walks walks and day trips out of the city as well.
p.s. This is my first trip to Europe and I'm very excited!
