Once suspicion is aroused, everything feeds it.

If the world were good for nothing else, it is a fine subject for speculation.

Spies are of no use nowadays. Their profession is over. The newspapers do their work instead.

To know all is not to forgive all. It is to despise everybody.

The first duty of a good inquisitor is to suspect especially those who seem sincere to him.

For sooner will men hold fire in their mouths than keep a secret.

I will never again command an army in America if we must carry along paid spies. I will banish myself to some foreign country first.

Secrets define us, they mark us, they set us apart from all the others. The secrets which we preserve provide a key to who we are, deep down.

It was funny how I could feel all alone and under surveillance at the same time.

If you read somebody’s diary, you get what you deserve.

There is nothing more deceptive than an obvious fact.

There is nothing makes a man suspect much, more than to know little.

Nothing is hidden from the eyes of the observing world.
