(Lord Vanderpool’s study. Alexander enters.)

Nothing! Where could he have hidden it?

Someone’s coming!

(hides)

(Lord Vanderpool and his clerk enter)

Lord Vanderpool: I’ve just received word that Niall Westmore has confessed to stealing the king’s seal. I must write to the king with my sympathy.

Clerk: Yes, sir. I’ll fetch paper and ink and we’ll return to the public office.

(exit)

Alexander: What? This can’t be right. Niall wouldn’t have done that, would he? I’ve got to find proof that he’s been framed!

(searches study)

I can’t find anything. Here are all of Lord Vanderpool’s secret dealings, but nothing about the king’s seal. Niall can’t have done it, but why would he confess?
