Dear Harriet Walter,
I have mastered the Hideously Deformed Windsor Knot.
Did you know that "Harriet Mary Walter" is an anagram of "Aware rather trimly"?
And also martyr aware hitler.
And Maltreat Harry Weir.
And twirly harem errata.
And heartily rewarm rat.
And lots of things to do with weather.
(Just "Harriet" can, of course, be rearranged as "hart ire," but phonetically speaking I think that's really more appropriate for Harriet Vane.)
