The first scene opens with a letter of arrival from Sherlock Holmes' niece, Angie Islington, a young 12-year-old noble girl who loves to investigate cases. One day, she stumbles upon a case of robbery which involves the Queen of the United Kingdom's ring that had gone missing during a garden party. Rewarded with a new title of honorary detective and a pendant an emblem of recognition, she embarks on an adventure. She is assisted by Inspector Jackson, a detective of the Scotland Yard, his dashing assistant Michael, and Angie's best friend Franck. They are going to settle numerous problems and bring peace back into the town.

Originally planned by Takahara Planning to have a story of a Gypsy girl travelling across Spain looking for her mother, with unbeknown reason transformed into a British detective drama. ^[1] Set in the 19th century of London, the whole city has an old rustic vibe, yet still appears to be modern. Landmarks one of such is the Big Ben is present in the story giving an insight of the foreign world of English history.

Inspector Jackson is never fond of Angie as he constantly feel threatened by the fact that the 12-year-old girl is much sharper and intelligent, eventually taking his spotlight away from him. Throughout the whole series, Angie has difficulty in gaining trust on adults whom she just met. That thought of doubt however, vanished as soon as they saw the pendant that the Queen awarded to Angie for claiming her lost ring. The pendant has an inscription behind it written "Protect Charlotte in my name; Victoria Queen of England"^{[dubious – discuss]}. Which tells anyone who are brave enough go against her will have to address to the Queen themselves.

The screening of the series was spread throughout Europe and the Arabs. During the 1980s, the release of Sherlock & Me from Portland Films in the UK and The Casebook of Charlotte Holmes in the U.S. Charlotte Holmes is an animation-only version made by Mexican TV, dubbed in Spanish. In America however, it was edited strangely, by using a real-life clip of Sherlock Holmes and his assistant Doctor Watson, indirectly introducing Angie as his niece through a letter.

In 1982, it was broadcast and dubbed in Italy.

Two years after the first release at the UK market, Charlotte made a second display as a "Bonus Cartoon" on Ringo Goes West, a Mountain Video's production. It is an English dub of Toei's Three Musketeers in Boots.

Angie's activities was last seen at France. In 1990 it was aired on French TV, ten years after her debut in most other parts of Europe and thirteen years since she was produced in Japan.
