This 1897 reality, that was once a major covert Infinity-Centrum battleground, has been turned into a popular Time Tours destination. "Holmes" is played by various actors (one or two of whom have real criminological experience) who on occasion have to deal with crimes committed by a Centrum Unattached agent who goes by the name "Moran". Because "Moran" doesn't want Infinity Patrol interfering he keeps his actions “in genre”.
Moran obviously refers to Col Sebastian Moran who appeared in "The Adventure of the Empty House". In that story it is stated he is "the second most dangerous man in London" (Moriarty being the first)
Even though Moran on occasion engages in airship piracy it is not clear if this reality is TL5 or a steampunk TL(5+1).
