The Duchess
It is no longer in my possession.

The Duke
I will no longer answer then for your son's safety.

The Duchess
Have you weighed well the consequences of this threat?

The Duke
You ought to know me by this time.

The Duchess
The trouble is that you do not know me. You will no longer answer for
my son's safety? Indeed--but you had better look after your own son.
Albert is a guarantee for the life of Fernand. If you keep watch on my
proceedings, I shall set a watch on yours; if you rely upon the police
of the realm, I have resources of my own, and the assistance of God.
If you deal a blow at Fernand, beware of what may happen to Albert. A
blow for a blow!--That is final.

The Duke
You are in our own house, madame. I forgot myself. Pray pardon me. I
was wrong.

The Duchess
You are more a gentleman than your son; when he flies into a rage he
begs no one's pardon, not he!
