Ghost Couple

The Ghost Couple is a duo of characters appearing in both the book from Tales to Give You Goosebumps and the television episode "The House of No Return".

Past
Originally, the couple's husband had built an entire house so that he and his wife could raise their child. However, he had made a mistake during the construction and they lost their first child to death by breaking the floor of the house. Their daughter also killed herself, which drove the couple mad for several months. At one point, authorities came to their house, only to find the couple dead and they took their bodies away. According to Danger Inc., after their death, the children of the neighborhood disappeared and they presume that the ghosts of the couple abducted them.

The House of No Return
While it's unclear whether the couple are haunting the house at first, this is confirmed when Chris Wakely is locked in by the trio of bullies. First he hears a lot of noises upstairs as if someone is moving. Then he was locked up when someone invisible barricaded the door with a wooden plank. Then he hears voices saying they are coming for him, causing him to scream in fear. The ghost couple physically appear upon arrival from the Danger Club to the haunted house. Glad to see them, they explain to the trio that Chris left after making a deal with them; if he left, he will be replaced by three children. Horrified, the trio ask if they can leave but the couple say no and that they will love them forever as they approach them threateningly. It is likely that the ghost couple killed all three children although this is not confirmed in the book or episode.

Personality
During their lifetime, the couple were jovial, happy and caring. They were devastated by the deaths of their children, gradually driving them mad and causing their deaths in some unknown way. As ghosts, they grew ghoulish and obsessed with having children again, trapping those who entered their old home like they did with Chris (even though they let him go) and the Danger Club.
