Just briefly: in a letter of March 2, 1931, Eliot alerts Hale to a book of criticism about his poetry by Tom Mac Greevy, which he has sent to her, and which she will see is not entirely correct. (In his interpretation of The Waste Land, Mac Greevy writes that Marie speaks the lines by the Hyacinth girl.) Rather, Eliot explains, Marie von Moritz was a middle-aged woman who lived in his pension in Munich, and he has transcribed her conversation exactly in the poem.
