March Daily Challenge - What you do for fun

Day 23 of MissyMoo's March daily challenge - What you do for fun: Do you dance? Read? Play? Tell us in a photo.

I could have done something to do with photography for this, as I do a lt of that for fun, and if it ceases to be fun I'll stop doing it, but for a change I thought I would show something else I do occasionally, also for fun, which is reading. My preferred choice when the reading is for relaxation is books in the style of John Le Carre, Frederick Forsyth and similar ones, and also those about the development of technology, so here we have "A most secret war" - about the goings on at Bletchley Park and similar things. Why did I choose this passage - well - radar has blips too!
