" Oh, I wasn’t suggesting you lied,” protested Blomquist. “I was merely raising it as a possibility. I didn’t say you should do that.” That itself, thought Ulf, is a lie. Blomquist was lying about lying, which, of course, was what happened when you started to lie. The first lie required a second—for consistency’s sake—and then a third and a fourth. Soon you would end up living in a vale of lies, where even the fact that it was night or day would be uncertain because the position of the sun could be denied if you so desired. "

― Alexander McCall Smith , The Man with the Silver Saab (Detective Varg, #3)
