Miss Daisy und der Mord im Flying Scotsman

The setting adds so much atmosphere and charm, but I wonder what inspired the choice of this particular train for the story.

The story picked up again towards the end, but I was curious if others found the middle section a bit slow or if it was intentional for character development.

I loved trying to piece things together as I read—were there any subtle hints that stood out to you as key to solving the case?
