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.

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

There is nothing more deceptive than an obvious fact.

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

Even a paranoid can have enemies.

Once suspicion is aroused, everything feeds it.

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

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

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