But is there any?

ISABELLA.
Yes, brother, you may live:
There is a devilish mercy in the judge,
If you'll implore it, that will free your life,
But fetter you till death.

CLAUDIO.
Perpetual durance?

ISABELLA.
Ay, just; perpetual durance; a restraint,
Though all the world's vastidity you had,
To a determin'd scope.

CLAUDIO.
But in what nature?

ISABELLA.
In such a one as, you consenting to't,
Would bark your honour from that trunk you bear,
And leave you naked.

CLAUDIO.
Let me know the point.

ISABELLA.
O, I do fear thee, Claudio; and I quake,
Lest thou a feverous life shouldst entertain,
