Frierson was returning to London from a  to rejoin his grandson Norman, his brother Kay, and twin cousin Scotty Doneeta.

Suddenly, the reunion is cut short when a shadow covers a door, revealing the shape of a bat, Fidget, as Norman, Kay, and Scotty hide in their rooms, Franklin attempts to fight the bat, but Fidget takes him hostage, and Norman sends Kay and Scotty to follow the bat and sends prepares to go off to find Basil of Baker Street to give him the details.

Hiram Flaversham, who has most recently returned to London with his daughter Olivia, hears of the news and comes across Norman, knowing he was looking for Basil of Baker Street himself, and takes him there. The landlady, Mrs. Judson lets them in to wait as Basil and his kindly assistant, Dr. David Q. Dawson barge in and introduce themselves. When the formalities are complete, Norman informs them that the peg legged bat, Fidget has returned and taken his grandfather hostage under orders of a Hungarian-born German savage beast, József G. Rathoug, cousin of the late Professor Ratigan. Rathoug coaxed the bat under orders like Ratigan before him.

Meanwhile, in Ratigan's former Lair, three of Ratigan's former thugs, who had confessed to Ratigan's plot to overthrow the Queen, are now working for her, are spying on Ratigan's cousin, the Hungarian-born German sewer rat, Rathoug, who with minions of his own, are mourning the death of his cousin and vows to kill Basil to avenge Ratigan. To do this, he starts by sending Fidget to spy on the heroes to get information on Basil. After thunder crashed and Fidget appeared at the window, frightening Norman, Basil realizes that fidget is still alive, even after he fell into the river.

Eventually, after Norman finds himself separated from the Detectives and Olivia, he finds Rathoug's lair and enters, hoping Franklin is in there, and sure enough, he's right. But before he can meet him again, Rathoug blocks his path, feeling cheated because no one would ever try to enter the lair after Ratigan's death, but cunning as he is, Rathoug congratulates Norman for being clever enough to make it inside and find the lair, and allows him to reunite with his grandfather inside, but he also finds that Kay and Scotty have cornered Fidget and are trying to reveal the reason for kidnapping their grandfather, but Norman stops them and tries to get them to leave with him so they can save their grandfather. Kay and an orphaned girl he met, Alana Chambers agrees, but Scotty is reluctant because he is more concerned with dealing with the bat and keeping Joanna, a girl he met in the lair safe, but they all come along then and escape.

While that happens, Basil learns that Fidget left behind a parchment with information that he collected while spying on them and after he escaped.

Back at Baker Street, Basil, Dawson and Olivia recount their adventures, as well as the queen's gratitude for saving the throne yet again. Afterwards, Basil thanks everyone for dealing with the case with him, especially Norman, who feels remorse for not holding his temper in when things at times went wrong, but Basil forgives him, and Olivia reminds him he did good on the case and kisses him, Joanna is accepted by Scotty to live with him, and Basil wraps it up, offering everyone in his flat tea and cheese crumpets.
