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

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

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

Secrecy lies at the very core of power.

Nothing is hidden from the eyes of the observing world.

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

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

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

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.
