You know, people call mystery novels or thrillers ‘puzzles.’ I never understood that, because when I buy a puzzle, I already know what it is. It’s on the box. And even if I don’t, if it’s a 5,000-piece puzzle of the ‘Mona Lisa’, it’s not like I put the last piece in and go, ‘I had no idea it’s the ‘Mona Lisa’!’
– Harlan Coben
