With quill and silver knife
She carved a poison pen
Wrote to her lover's wife:
"your husband's seed has fed my flesh".
[ Lyrics from: http://www.lyricsfreak.com/k/king+crimson/the+letters_20078608.html ]
As if a leper's face
That tainted letter graced
The wife with choke-stone throat
Ran to the day with tear-blind eyes.

Impaled on nails of ice
And raked with emerald fire
The wife with soul of snow
With steady hands begins to write:

"i'm still, I need no life
To serve on boys and men
What's mine was yours is dead
I take my leave of mortal flesh"
