‘The thing about the captain, see, I read this book once… you know we’ve all got alcohol in our bodies… sort of natural alcohol? Even if you never touch a drop in your life, your body sort of makes it anyway… but Captain Vimes, see, he’s one of those people whose body doesn’t do it naturally. Like he was born two drinks below normal.’ ”
