My one problem with Kindle is I often forget the title of what I'm reading, as it isn't in front of me like with a paper book. For some unknown reason, my Kindle didn't turn on to the book I'm reading and I'd no idea what it was called so I typed "spanish detective, wartime London novel kindle amazon US embassy typist and driver murdered Kennedy"
Up came the Title" Princes Gate" and I downloaded it again.
The marvels of modern technology! I also love the way you can find a poem or song if you only recall a fragment.
