But guys we have sweet Victor and all but just think about it. Assassin!Victor.
Assassin!Victor's next target being Sherlock Holmes, the detective he's been watching for a very long time. The target is supplied by a very high up mafia boss who Sherlock pissed off.
Sherlock already being on the case of a highly skilled assassin that has taken out at least twenty people since the beginning of the long case. He leaves no evidence whatsoever and the cases go cold every time.
Victor still accepts the hit just for the game and the fun of it and one day Sherlock comes home to find it completely dark in his flat and when he goes into the living room, seeing the rough silhouette of a man on his chair. Victor would have already removed every bug in the flat and Sherlock knows this so he just sits down on the chair in front of Victor, up close being able to see his features only slightly.
He can tell almost immediately that Victor is the person he's been looking for but they don't say anything. After sitting in complete silence for a few long moments Victor finally stands and walks over to Sherlock to place a file on his lap and leans down to press a light kiss to his lips before disappearing completely.
The file contains the needed information to catch every criminal in the mafia boss' web. The mafia boss that the Yard finds just a day later with a bullet placed perfectly between his eyes and a note on his chest.
"Catch me if you can, Mr Holmes. xx"
