In a wild flash of cross-association triggered reading the current "Favourite Roundel" thread, I suddenly remembered Gavin Lyall's aviation thriller "Shooting Script", which I read years ago, liking it really well.
Perhaps you have read this book or some other of his aviation thrillers? Then I'd be interested in your opinion (or recommendations)!
According to the English Wikipedia article, his aviation-related work comprises of "The Wrong Side Of The Sky", "The Most Dangerous Game", "Shooting Script", and "Judas Country".
I liked "Shooting Script" for its mix of credible characters, surprising ideas, realistic detail and laconic humour.
Is Gavin Lyall a well-known author in Britian? The Wikipedia compares him to Ian Fleming in one sentence (at Lyall's peak in his career), and he was actually translated to German, so I think it's safe to assume he was not just some obscure figure - but has anyone here ever heard of him?
