Film/TV recommendation: "Page Eight" (excellent, from PBS Masterpiece Contemporary)
via pbs.org
I watched this last night on my (free) PBS app on my iPad, but it's also available to watch online at: http://www.pbs.org/wgbh/masterpiece/watch/pageeight.html
I've read and watched a lot of espionage (non-fiction as well as fiction). This was excellent with some top-flight actors. No chase scenes, gun battles, or explosions, but very well-plotted and..cerebral.
