Finn Shelby is the youngest of the Shelby siblings and a member of the Peaky Blinders.
Unlike his three older brothers, Finn did not fight in the First World War as he was not old enough to be recruited. Though he is a Peaky Blinder, his brothers often watch over his safety as he learns to fit better and grow into the role.
Series 1 · 1919Edit
Series 2 · 1922Edit
Although Finn is older now, his brothers still shield him from the violence of their life, and he also evidently has trouble fist fighting, a quality that separates him from his older brothers as they are all naturally good at it.
At the day of the grand re-opening of The Garrison Pub, Thomas tells Finn to go get his brother Arthur Shelby Jr. to come to the event. After seeing Arthur's violent episodes many times, and with the suggestion from his brother Thomas, Finn introduces Arthur to a drug called Tokyo (cocaine), and tells him to only use it during race days and special occasions.
Series 3 · 1924Edit
Finn is 16 now but still kept away from a lot of the business by Arthur and John but is allowed to be present in the meeting with Vicente Changretta with Arthur, John and Isaiah. He also witnesses the murder of sister in law Grace Shelby and kills the killer with his brothers.
Arthur is Finn's oldest brother and the one he is closest to out of the four. He and aunt Polly raised Finn when his mother died and his father abandoned the Shelby Family. Maybe this is the reason why Arthur tries so hard to keep Finn out of the illegitimate business. Arthur and Finn are first seen together in Season 2, at the day of the grand re-opening of The Garrison Pub.
