Say'st thou?

SHUISKY. I say that in that case the blood in vain
Flowed of the young tsarevich, that Dimitry
Might just as well be living.

VOROTINSKY. Fearful crime!
Is it beyond all doubt Boris contrived
The young boy's murder?

SHUISKY. Who besides? Who else
Bribed Chepchugov in vain? Who sent in secret
The brothers Bityagovsky with Kachalov?
Myself was sent to Uglich, there to probe
This matter on the spot; fresh traces there
I found; the whole town bore witness to the crime;
With one accord the burghers all affirmed it;
And with a single word, when I returned,
I could have proved the secret villain's guilt.

VOROTINSKY. Why didst thou then not crush him?

SHUISKY. At the time,
I do confess, his unexpected calmness,
His shamelessness, dismayed me. Honestly
He looked me in the eyes; he questioned me
Closely, and I repeated to his face
The foolish tale himself had whispered to me.

VOROTINSKY. An ugly business, prince.
