The character of Alice Garvey was written out of Little House on the Prairie television show by having her character die in the fire at the school for the blind, alongside Mary and Adam’s baby. The death of her character was a shock at the time as she was a favorite character of many fans of the tv show.
Alice Garvey was played by Hersha Parady and she reportedly wanted out of her contract for the show in order to focus more on raising her own family instead.
Usually for popular characters, writers of a show will leave the door open for the character to return. But in this case, the show was nearing the end of its run and the death of Alice Garvey and the baby provided huge ratings for the show.
