Synopsis

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. Sarah Jane and the gang discover the secrets of Erasmus Darkening, but are they too late? As ghosts from the past rise up, and the quest to find the missing children reaches a climax, it seems that nothing can stop the ancient alchemist's rise to victory.

Rivers is telling the story to Sarah Jane, Clyde and Rani and her assistant Toby. Luke is at home as their stand by in case anything goes wrong. Sarah Jane splits up from the group and finds a book on the history of the manor. She turns round from the book case where she is reading from and unknown to her the books begin moving. Clyde and Rani also do this they go outside and find a shed. There is a fountain outside all of a sudden the fountain goes of and some wet foot prints appear to the shed. They hear a young girl cry. It stops as Clyde pulls a sheet of a Mirror. All of a sudden a face appeares on the mirror of a man. They ran back into the manor to find Sarah Jane. Meanwhile in the control room the camera in the playroom cuts out. Rivers goes to investigate. All of a sudden the nursery monitor starts to play. Then seconds later Rivers vanishes. They all go to investigate and they find that all the toys come alive. On the mirror in the room a message appears saying "Get Out". Clyde and Rani begin exploring and find a secret passage way, they go down and find Erasmus' lab. Meanwhile Sarah Jane goes out and finds a balcony a creature in the bushes with red eyes appears it advances towards Sarah Jane. But Lord Marchwood's ghost manifests and he fights it of. Clyde and Rani find a computer, then when they turn around they see Erasmus Darkening.

She warns her that "he is coming for you" and then disapears. Sarah Jane reunites with Clyde and Rani and then they find Lord Marchwood. Sarah Jane believes they're not ghosts. Toby, Sarah Jane, Clyde and Rani discover all the people that have disappeared except for Professor Rivers who hasn't been absorbed yet. Erasmus arrives and they all disappear. Erasmus tells them he will come for them all. Sarah Jane knows Erasmus is playing with them. Sarah Jane and Toby investigate Erasmus' secret chamber while Rani and Clyde distract Erasmus. 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. Clyde and Rani run into the pavilion. Sarah Jane and Toby get interrupted by Erasmus. Sarah Jane works out that the machine is giving Erasmus and all the people that disappeared eternal life. She also works out the creature that attacked her earlier came through the machine. Lord Marchwood once again rescues Clyde and Rani again by slaying the creature.

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.
• Neither Mr Smith nor K9 appear in this episode. Mr Smith is mentioned.
• This isn't Callum Blue's first experience playing a "ghost", as he is well known for his role as Mason, a grim reaper in the American series Dead Like Me.

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).
