Iโve worked out a way to get @Robot_Maria to send PMs via the API, and I have a list of characters and their icons. So all I need is 2-4 players.
I did change some icons to match available emoji (pipe to monocled face, necklace to woman, police badge to policeman), so the list of suspects is:
Sebastian Moran

Irene Adler

Inspector G. Lestrade

Inspector Gregson

Inspector Baynes

Inspector Bradstreet

Inspector Hopkins

Sherlock Holmes

John H. Watson

Mycroft Holmes

Mrs Hudson

Mary Morstan

James Moriarty
