Yuukoku no Moriarty OVA

A vandalized painting catches William James Moriarty's attention when he recognizes the name of an artist he knew in childhood. He travels with Louis to Bath to meet the man, but the man presenting himself as the artist is not the childhood friend William remembers. With Sherlock Holmes and John Watson becoming involved as well, the visit turns into a search for an old companion and the truth hidden behind the damaged artwork.

On another day, the Moriarty household faces a very different kind of crisis: successfully hosting a tea party. Between preparations, guests, and domestic confusion, grand conspiracies briefly give way to a lighter glimpse of the brothers and the people who share their home.
