OK, I've had a hard time deciding how to rate this book. I think the story itself was a little weak compared to the twists and turns of modern spy thrillers, but I am absolutely enthralled in how the story was told. Picture after picture were painted in my mind, and I found the idioms extremely delightful. Comparing a persons personality to "a different pair of shoes" was one that has stuck in my mind.
I had a little trouble with the mental pronunciation of some of the names of the people and the places, but soon adopted my own pronunciation. Once I had adapted to the style of writing ( early 20th Century) the reading became easier.
Having said that, I intend to reread this book...and maybe even tackle Pilgrims Progress (you'll understand this after reading the book). Stand Fast, Mr. Standfast!
