I don't have much time to read these days, but I'm in the middle of a great one by Ishiguro: When we were Orphans. It's not a gripping read, even if it's a sort of detective nove, but that's Ishiguro's style - really flegmatic and rather old-fashioned (I sometimes think he writes English like a foreigner would, with great care, but maybe I'm just being influenced by his surname...).
Others I loved by him: obviously The Remains of the Day, and Never Let me go (sort of science-fiction that hides its own nature for quite a long time).
