A haunted house, with mysterious whispers and secrets in the shadows attracts Sarah Jane's attention. When Professor Rivers and the gang investigate an old legend, a monstrous creature appears in the night as the terrifying grasp of Erasmus Darkening reaches out from centuries past.

Toby tells Sarah Jane about a creature who came into his room and watched him every night when he was younger. Rani and Clyde are chased by something into a game room. When all the games start playing themselves they run outside and get locked out. Sarah Jane and Toby find Erasmus' machine. Sarah Jane suspects that Erasmus was trying to get home to another galaxy with the machine. The machine malfunctioned and all the people that disappeared got trapped between dimensions.

Story notes

• This is the only Sarah Jane Adventures story prior to his departure in SJA: The Nightmare Man not to have featured Tommy Knight as Luke Smith. This was due to Tommy being busy taking his GCSE exams.

Ratings

to be added

Myths

• The faceless being that Toby saw as a child was The Trickster.
• Some people believed that Erasmus Darkening may have been a Time Lord. Sarah Jane commented on Darkening's manipulator having TARDIS-like qualities. Clyde made reference to some aliens looking human and used the Doctor as an example. He seemed obsessed with living forever as if he were a Time Lord on his last regeneration. His clothing was suggestive of Time Lord clothing. The counter argument is that the Doctor has indicated that he "would know" if there were other Time Lords still in the Universe. Erasmus was, however, trapped between dimensions, which it is hypothesised may have "hidden" him.

Filming locations

• The Haunted House in the episode was previously used in Series Four of Doctor Who in DW: Forest of the Dead.

Production errors

• In Part One, when the Professor is taken, her scream can be heard, but the cameras she is using have no audio, as she earlier uses her radio to talk.
• Mobile phones are said to interfere with equipment, while walkie-talkies do not, however, all hand-held transmitters currently in common use are actually more powerful sources of EM radiation than any mobile phone conforming to current cellular network standards.
• Considering the secret passage hasn't been opened for years - possibly centuries - the presence of illuminated electric lightbulbs on the wall is puzzling (as is the need to use flashlights in the obviously well-lit corridor).
