When we had a new roof put on our house years ago, we started noticing all the roofs on houses – those that were new, those that needed to be replaced, etc. When we moved here I started noticing Switzerland in various books, books that are not about this country.
I first noticed it in John Irving’s A Prayer for Owen Meany. The psychologist in the book is from Switzerland and his name is Dr. Dolder. The Dolder Grand Hotel, a 5-star resort, sits on a nice overlook over Zürich. There is also a Col. Eiger (Eiger is one of the mountains near the Jungfrau).
Jonas Jonasson mentions Switzerland in two of his books, The Hundred-Year-Old Man Who Climbed out the Window and Disappeared, as well as The Girl Who Saved the King of Sweden. Ishiguro’s The Unconsoled, though set in an undisclosed European small city, does mention Zürich, and Richard Morais who wrote The Hundred-Foot Journey was raised in Zürich.
I’m sure I will come up with more references as I continue to read.
