Grace Helen Shelby (née Burgess) was an Irish barmaid who took up employment at The Garrison Pub, and secretly operated as an undercover agent for the Birmingham Police. Her mission involved getting close to Thomas Shelby whom she fell in love with. He too returned the sentiment but was heartbroken when he discovered her treachery.
Having left for New York, Grace returns mid-way through 1922, married to an American, but when she reunited with Thomas, it was clear their prior feelings have not dissipated. The somewhat awkward reunion easily culminated into a brief tryst which led to Grace's pregnancy. She married Thomas sometime in 1924, following her first husband's suicide.
Grace is an Irish woman of a Protestant background. When undercover she claimed she was from Galway, and her accent (maintained throughout the series) points to Galway likely being where she was raised . Her father, a colleague of Chester Campbell in the police force, was killed by the IRA.

Inspector Campbell Edit
As of season one, Chester Campbell is Grace's commanding officer and supervisor whom she worked closely with. Prior to their arrival in Birmingham, little is known of their relationship beyond that he had worked together with her father in the past.
Early in the season, Inspector Campbell exhibited what seemed to be fatherly concern and affection for Grace, when he tells her to be careful in her undercover work around the Peaky Blinders and particularly, Thomas Shelby.
As the season progresses, however, Inspector Campbell becomes more explicit about his affections for her. This culminates in a marriage proposal after the stolen guns are found. Her rejection comes as a surprise to him, despite the fact that she explicitly asked him to spare the life of Thomas Shelby, not in the capacity of an agent, but asking for his word on the matter "as a gentleman". His surprise quickly turns to anger as he deduces Grace's feelings for Thomas.
