Accidental Soulmates- A Mormor Fanfiction

Sebastian Moran is a sniper, working for the only consulting criminal in the world, Jim Moriarty. However, Seb has never even seen his face. He gets his assignments from someone entirely different who gets assignments from someone else, the same goes on several times until you reach Moriarty himself. Seb has never had direct contact with him and isn't sure if he wants to. However, one day, he gets a text from an unknown number claiming to be Moriarty, threatening to turn him in to the authorities, and telling him to come to the enclosed address or risk loosing everything. Seb doesn't have a choice, so he meets with Moriarty for the first time. Seb never expected to fall in love with his captor, but accidents happen, don't they?
(Sorry the title sounds like a romcom title. I tried.) I don't own the fanart on the cover. Thanks for reading.
