I've been trying to read more non-fiction
To Catch a King by Charles Spencer was a chance pick up and a good one. The book charts the escape of the young Charles II after the disastrous battle of Worcester as he zig-zagged down to the coast and eventual safety, in many cases only an hour or so ahead of his pursuers. Most of us have heard about his hiding in the Boscobel oak but the story of his escape is so much more than that (he was in the oak for one day and took nearly six weeks to get to safety), the king was resourceful and quick thinking and he had some incredibly loyal supporters willing to risk all to help him. The narration takes a bit of time to get going but once it does it's completely compelling.
A Woman of No Importance by Sonia Purnell. Virginia Hall was sent to Lyon in 1941 by SOE, the fledgling British intelligence service, the whip up the French resistance under the pretence of being a journalist. She was the first woman to be sent to France, nearly the first agent, was American, not British, and despite being red-headed, tall and having a wooden leg she built up one of the largest spy networks, became a target for the Gestapo, sprung Allied prisoners from jail and created huge army of civilian guerrillas who played a vital role in occupying Nazi divisions during the 1944 invasion so they couldn't march up to Normandy. The blurb says it reads like a thriller and indeed it does. I can't recommend it more highly.
