February 14, 1587.

My dear Brother, I would you knew (though not felt) the extreme dolor that overwhelms my mind, for that miserable accident which (far contrary to my meaning) hath befallen. I have now sent this kinsman of mine,* whom ere now it hath pleased you to favour, to instruct you truly of that which is too irksome for my pen to tell you. I beseech you that as God and many more know, how innocent I am in this case : so you will believe me, that if I had bid aught I would have bid by it. I am not so base minded that fear of any living creature or Prince should make me so afraid to do that were just; or done, to deny the same. I am not of so base a lineage, nor carry so vile a mind. But, as not to disguise, fits not a King, so will I never dissemble my actions, but cause them show even as I meant them. Thus assuring yourself of me, that as I know this was deserved, yet if I had meant it I would never lay it on others’ shoulders; no more will I not damnify myself that thought it not.
The circumstance it may please you to have of this bearer. And for your part, think you have not in the world a more loving kinswoman, nor a more dear friend than myself; nor any that will watch more carefully to preserve you and your estate. And who shall otherwise persuade you, judge them more partial to others than you. And thus in haste I leave to trouble you : beseeching God to send you a long reign. The 14th of February, 1587.

Your most assured loving sister and cousin,
ELIZAB. R
