I forgot to mention in my last posting that I did one other thing last Saturday; I went into the local park to see what the "Bedford Park Festival" could offer, and spent an hour going through the stock of a fantastic second hand book stall. Bliss. £2.50 later I had a Hornblower I hadn't read before, a Zoe Oldenbourg I hadn't read before, the "Collected Letters" of D H Lawrence (win!) and "The Prestige" by Christopher Priest. Sadly it's the film tie-in edition, with a very silly jacket illustration.
I haven't seen the film, and now am wondering how on earth a novel with such convoluted nuances of unreliability among its several narrators could be filmable in the first place (I'm suspecting heinous simplification was involved).
Anyway, I finished it at 1am last night. VG, & highly recommended.
