" The police are not witlings; they will know that each of you may have had a private reason for your reserve not relevant to their investigation; but they will also know that if one of you was involved with Carol Mardus regarding the baby, and if you killed Ellen Tenzer, you would certainly have omitted her name from your list and you would not have identified the picture. So they will be importunate with all of you. "
― Rex Stout , The Mother Hunt (Nero Wolfe #38)
