Lettice Babblejack
Miss Lettice Babblejack makes it into two of the yearbooks. In Discworld (Reformed) Vampyres' Diary 2003 she is referenced as a young and somewhat waif-like vampire and a member of the committee of the Black Ribboners' League of Temperance. She is in charge of music and of playing the harmonium at the jolly sing-songs that accompany Black Ribboner meetings (except on Tuesdays). She also appears in Discworld Thieves' Guild Yearbook and Diary 2002 as a musician and music teacher, possibly at the Thieves' Guild school..
