I have wanted . . . to commit a murder myself. I recognized this as the desire of the artist to express himself! . . . But-incongruous as it may seem to some-I was restrained and hampered by my innate sense of justice. The innocent must not suffer.

You can only really get under anybody's skin if you are married to them.

No innocent person ever has an alibi.

The supernatural is only the natural of which the laws are not yet understood.

Nobody believes in magicians any more, nobody believes that anyone can come along and wave a wand and turn you into a frog. But if you read in the paper that by injecting certain glands scientists can alter your vital tissues and you'll develop froglike characteristics, well, everybody would believe that.
