Muriel Tarr Kreiner (ca. 1898-1963) was the wife of Otto Kreiner. When she became the mother of Fitz Kreiner at the age of thirty-eight, her history of illness made it difficult to look after her child. (PROSE: The Taint)

When Fitz was a child, his mother had a bird table in the garden on which she would put pieces of suet for the winder birds. (PROSE: Reckless Engineering)

When Fitz was six, he lost Muriel in Woolworths. (PROSE: The Ancestor Cell)

When Fitz was eight, Muriel took him to the seaside. Despite her warnings, Fitz fell off a wall, spraining his ankle. Despite her illness, if Fitz was ever bullied at school she would go to the school and swear at his headmaster. (PROSE: Vanishing Point)

She had once taken Fitz to a second-hand bookshop where he glanced at a Lovecraft book. She "whalloped" him because she thought it was a book about sex. (PROSE: The Taking of Planet 5)

After Otto's death and her third lapse into illness, young Fitz finally had to be put in care. The Benelisa program resulted in her death in 1963. (PROSE: The Taint)
