Slow train to Switzerland by Diccon Bewes. The author is British, but he lives in Switzerland, he writes about Switzerland and I read the book on a train on my way to Switzerland :-) So it counts.
Slow Train to Switzerland is based on two long lost, then found travel journals written my the English lady Miss Jemima. She took part in Thomas Cook´s first conducted tour of Switzerland back in 1863. Diccon Bewes decided to use Miss Jemima´s travel tale as an inspiration for his own, 150 years later. Does it, writes about it, publish the book, I found it by chance a few years ago, brought it with my on my own travel to Switzerland, a tour with the Bernina Express, which was given me in my 60th birthday this spring. And I love it. The book and my tour.
