Here finally is "Bluebeard" as I should have called it before, and it is short but truly amazing.

Bluebeard

by Sylvia Plath

I am sending back the key

that let me into bluebeard's study;

because he would make love to me

I am sending back the key;

in his eye's darkroom I can see

my X-rayed heart, dissected body :

I am sending back the key

that let me into bluebeard's study.

Sylvia Plath killed herself by sticking her head in an oven and breathing the fumes until she was dead.
