Just finished reading this and am frustrated - writing this on the tiny chance that someone else who has read it has noticed the same thing. At the beginning, when Felix is warned by George that the money-laundering scheme has been discovered, he says ' It's the Big Man' (the nickname for their old headmaster and Felix's father-in-law). I read the whole novel thinking that there was going to be a brilliant twist in that he (the 'Big Man') would be involved in the fraud too. But nothing. So why on earth does he say it?
