Duke. Traitor!

King. Yes; and a foul one. My lords, suspend
Your wonder. We thank ye. Prodigy to thy blood,
We have given you leave to wanton in your guilt
And see at what mighty impiety it would reach;
To fasten you the surer in your toil.
Take your places. Durst thou derive the glory
Of our grandsires to thyself, whilst with unnatural hands
Thou tear'st their graves up; mingling blood and shame
With their bless'd dust? Have we not shar'd our kingdom with thee:
Let thee into our heart nearer than nature,
If possible? And could all this beget
No better thanks than poison? The very thought
Unnerves my joints.

Duke. Treason? Who dares avow it, sir,
Or charge the least stain upon my loyal bosom,
And make it good? I challenge all mankind,
And envy from the nether hells; 'tis but
Some engine to betray me to you.

De C. I did but quit a sin,
Which would have betray'd us both eternally,
And bore so sad a shape of horror,
As it affrighted all within me, and, like a frenzy,
Held me, till I had purged it from my bosom.

Duke. Had thy revenge no other way but this,
To undermine the virtue of nature against itself?
My lords, there's forgery in't, poison, and treason!
It did amaze my innocence. Sounds, that my blood
Do shiver at. And did not I see his father's treason
Blush yet upon his brow, I should not think
Castile infected with the thought.

1st Judge. My Lord De Castro,
What proof or circumstance have you to urge
This clearer to his highness?

Duke. Grave patriots of the law,
Give me your leave in this, that would blemish
The honour of my fame for ever. Let him produce but any
That may accuse me to your reverend judgments,
And Bereo will lay down his head to the block.
But I know your wisdoms will discern a plot in't:
And how far he stands incompetent against me
In faith and honour.

King. What say you, my lord?

De C. Sir, what I have told your Majesty—my life
Shall make good on my torture: my brother being dead,
Heaven only and my conscience can clear it:
And to quit my innocence of malice, your own conscience
Must tell you, my lord, that when first you used my brother
To ensnare me, and press'd it in the duchess's garden,
How much I argued to divert you; but then—

Duke. My lords, I desire justice and reparation
On the villain.
