Seven Seas will release Young Miss Holmes, an all ages manga Sherlock Holmes pastiche, in March, timed with the home video release of Sherlock Holmes: A Game of Shadows.  Young Miss Holmes (Christie: High Tension in Japan) revisits several Sherlock Holmes stories from the viewpoint of Holmes’ precocious niece. 
The first release, a double-sized omnibus, includes the multi-chapter story arc “The Adventure of the Sussex Vampire,” with Dance in the Vampire Bund heroine Mina Tepes.  Dance in the Vampire Bund has been a big hit recently (three of the top 20 adult graphic novels in bookstores in the most recent month, see “'Sailor Moon' Is #1”).  The volume also includes an epilogue by Dance in the Vampire Bund artist Nozomu Tamaki.
