Yuukoku no Moriarty OVA

The Moriarty series explores the life of William James Moriarty, particularly in two separate storylines. In the first, a vandalized painting prompts Moriarty to investigate, teaming up with Sherlock Holmes and John H. Watson to uncover the truth behind the damaged artwork. This case takes them to Bath to meet the artist, only to discover that the person in question is not who Moriarty expected.

In another storyline focused on the Moriarty household, the family hosts a tea party, but this seemingly ordinary social event conceals their underlying activities. As they navigate this event, they must protect their home and their operations from those who might stumble upon their secrets, including curious aristocratic women.
