Rose Mamusu[1] Grant is the mother of Peter Grant. She is a light skinned Sierra Leone Creole.[2] Before arriving in England she worked at the library in Freetown[3] with Elsie Winstanley.[4]

When Peter introduced Simone Fitzwilliam to his mother, Rose became furious. She recogniced Simone as a woman who tried to seduce her husband Richard years ago. Since Simone still was young, Mrs. Grant deduced that Simone was an evil witch.[5]
