I thought I'd never come across God's Proofreader. For one thing I don't read many very clever books these days, and another, if I do I usually borrow them off my parents. Imagine my surprise when I saw this in William Brandt's Alpha Male. There were another couple of pencil scratches - another similar offence involving a double possessive, and a query on the word 'mojo'.
I feel like I've hit the jackpot.
