PRINCESS.
The next to hers. But of what use is that?

DOMINGO.
Oh, for some skill in locks! Have you observed
Where she is wont to keep her casket key?

PRINCESS (in thought).
Yes, that might lead to something; yes, I think
The key is to be found.

DOMINGO.
Letters, you know,
Need messengers. Her retinue is large;
Who do you think could put us on the scent?
Gold can do much.

ALVA.
Can no one tell us whether
The prince has any trusty confidant?

DOMINGO.
Not one; in all Madrid not one.

ALVA.
That's strange!

DOMINGO.
Rely on me in this. He holds in scorn
The universal court. I have my proofs.
