Never trust your Honour to another, unless you have his in Pledge.

Never trust your Honour to another, unless you have his in Pledge. Arrange that silence is a mutual advantage;disclosure a danger to both. Where honour is at stake you must act with a partner, so that each must be careful of the other’s honour for the sake of his own. Never entrust your honour to another; but if you have, let caution surpass prudence. Let the danger be in common and the risk mutual, so that your partner cannot turn king’s evidence.
