The sulking boggart is most displeased to find himself mistakenly shipped to Canada inside an antique desk destined for Emily Volnik's room.

Filching oatcakes quickly becomes a thing of the past as the boggart finds all sorts of new ways he can drive this modern family crazy.

Back in Scotland, the mail carrier swears his van is haunted when he delivers Tommy's Christmas package all the way from Canada.

Tommy Cameron is a person who has known the boggart for years as a frequent nuisance at his family's general store in Port Appin, Scotland.

Tommy sends Emily and Jessup a few postcards after they leave Scotland, and he becomes an invaluable resource when they need someone to explain what a boggart is and how to deal with it.

Thirteen-year-old Tommy is also a computer whiz, and it is with his help that the boggart is finally shipped back home to his beloved Scottish castle.

She is, unfortunately, a very highly strung woman, and the sight of the boggart flinging furniture out the window or levitating expensive wine glasses in her antique shop sends her into near-hysterics.

Maggie is apt to blame the children for the chaos that is taking over their house, and she is easily convinced by the evil Dr. Stigmore that Emily needs to be institutionalised.

Fortunately, Maggie discovers that Dr. Stigmore is exploiting Emily's so-called "poltergeist" to make himself famous on a tabloid show, and promises that she will never let him near her family again.

At the end of the story, he is safely ensconced in his new home—which he has updated with central heating and electric lights—with his new tweeds in the closet, his new puppy curled in the hall, and his little grandnephews asleep in their beds.

The boggart cannot believe his good fortune to have in his castle not only a kindly old man, but small children to play with and a dog to tease, and sews their shirtsleeves closed to welcome them properly!

It details the adventures of Princess Imogen (played in this version by the actress Meg), whose father King Cymbeline refuses to let her marry the noble but poorly born knight Leonates Posthumus.

The two brothers and their guardian eventually save Britain from an invasion of Romans, and King Cymbeline, mourning the death of his evil Queen and his wicked stepson, rediscovers his long lost princes and their sister.
