Just finished le Carré's Our kind of traitor. Something of an obsession, as I've read all of his previous works, but felt that - although well written and topical - it didn't have the interest of his earlier Cold War-based novels. Perfect spy remains my favourite.
Now wading through Petzold's Annotated Turing - heavy going in places (for me, at least), but very well explained and proving more accessible than I'd feared. Many 'aha - now I understand that' moments along the way. Deeply sad choice of 'leisure' reading, I know, but sometimes relish a challenge.
