I admit," I said, "that a second murder in a book often cheers things up." - Hastings

There is no greater mistake in life than seeing things or hearing them at the wrong time.

There are questions that you don't ask because you're afraid of the answers to them.

Ideas are like everything else. They've got to be marketed.

Assumptions are dangerous things.

I have often had occasion to notice how, where a direct question would fail to elicit a response, a false assumption brings instant information in the form of a contradiction.

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.
