Heather Badcock meant no harm. She never did mean harm, but there is no doubt that people like Heather Badcock (and like my old friend Alison Wilde), are capable of doing a lot of harm because they lack - not kindness, they have kindness - but any real consideration for the way their actions may affect other people. She though always of what an action meant to her, never sparing a thought to what it might mean to somebody else.

There are doubtless certain unworldly people who are indifferent to money. I myself have never met one.

Evil never goes unpunished, Monsieur. But the punishment is sometimes secret.
