An unnamed story was to have been the third of four Halloween specials for The Sarah Jane Adventures, but due to the death of Elisabeth Sladen was never produced. Like the other Halloween specials, it would have been a live 2011 broadcast.
It would have seen Sarah Jane and her gang encounter a Gargoyle-like creature.
It would have been succeeded by the last Halloween special, Night of the Spectre, this time written by Phil Ford. (DWMSE 32)
