She said that an Evil spell was cast on the Hotel by Emeline Partridge, She saw it herself (When she was actually lying about it.) and Buzzy and his niece Anna go and solve the Mystery of what happened to them.
Buzzy meets a few friends on the way Including Chris Todd (Dewey's grandson) and Claire Poulet (an actress from France, in French Poulet means chicken). Abigail appears again in Buzzy's House and tells more lies about Emeline. She says that the 5 people have identifiers and if the wicked Person gets all five identifiers the spell will be re-casted and all of the people in the hotel will be sent to the underworld of eternal misery.
A counterspell has to be casted on All Hallows Eve which is her birthday. Then Abigail was next seen with Anna (Played by Kirsten Dunst) and Buzzy and Chris "Quartermaster" Todd (Q for short). Q gives Abigail the hat that belonged to Dewey and Abigail still has the Hair from Sally Shine and the Handkerchief from Emeline Partridge.
When Anna talked about Emeline Partridge she says "Beware of her, Evil does not die." and Buzzy and anna go inside the hotel to find the rest of the identifiers. When Buzzy and Anna found the last of the Identifiers the Spirit of Gilbert London appears Pouring Wine into a cup. Dewey was mad about it and Gilbert calls Dewey a Stooge. Sally appears and mad about Gilbert calling Dewey a stooge. Dewey and Sally were fighting (with words) with Gilbert and Carolyn Said to Stop. Carolyn shows them that their friend named Claire Poulet was actually her stage name. Dewey starts to worry that it's his fault that he got them all dead.

Buzzy went downstairs to find Abigail and told her to stop. Abigail told them that the elevator will crash the way it was supposed to, 60 years ago. Anna along with the spirits (except for Sally) was getting worried. Abigail told them why she was doing it and she thought everyone forgot about her and her birthday too.
