Shirley Jackson said this quote

We believed optimistically that Laurie was a reformed character. I told my husband, on the last day of Laurie's confinement, that actually one good scare like that could probably mark a child for life, and my husband pointed out that kids frequently have an instinctive desire to follow the good example rather than the bad, once they find out which is which. We agreed that a good moral background and thorough grounding in the Hardy Boys would always tell in the long run.(Arch-Criminal)
