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

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.

Three may keep a secret, if two of them are dead.

There is nothing more deceptive than an obvious fact.

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

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.

Secrets are rarely betrayed or discovered according to any program our fear has sketched out.

We must not always talk in the marketplace of what happens to us in the forest.

There is a sickness among tyrants: they cannot trust their friends.

The life of spies is to know, not be known.

Nothing is hidden from the eyes of the observing world.

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