If you're not familiar with DeMille, you should be. Most of his work would probably be classified as military or espionage thrillers, there are a few regular thrillers, but Charm School definitely falls into the espionage category.
In Charm School (published in 1988) an American tourist in Russia takes a wrong turn and picks up a hitchhiker who spills some pretty intense state secrets. The tourist calls the American embassy, but by the time they get there to collect the guy, he's gone without a trace. Course the plot is much more complicated than this and involves KGB plans and a few key American players who have to unravel the whole thing. Super fun and a crazy page-turner.
I tend to get bogged down with political plots and so most espionage fiction goes completely over my head. I'm not embarrassed to admit that I am not very politically minded nor do I follow many current events - they tend to stress me out and only lead me to believe apocalypse is inevitable, so I think it's better for my health to avoid most of it. Charm School, and actually all of DeMille's work that I have read to date, are very easy to get into. I've never had any problems grasping the stories at all. I haven't read the whole DeMille collection just yet, but of the ones I have read Charm School remains my favorites.
So, I know you want something to tide you over until you get to watch Daniel Craig in the newest 007 movie (at least I do) and I highly suggest letting DeMille fill the gap. You won't be sorry.
