“Betrayal takes two, who did it to who?” That line of Richard Hell’s has been buzzing round my brain since reading the books in Len Deighton’s superb spy trilogy, Berlin Game, Mexico Set and London Match, in rapid succession at the very start of this year. The series was written and based in the early-to-mid-1980s Cold War-era, featuring intelligence officer Bernard Samson. This is the first in a trio of trilogies featuring Bernard: is there a word for that? Not that I know of. Ennealogy doesn’t quite cover it. Words are funny things, aren’t they? You can feel lost without a book, and you can lose yourself in a book. This particular trilogy is perfect for getting lost in.
