Episode 1.1 Edit
Thomas rides a big black horse into the Chinese quarters in Birmingham, where the horse is subjected to a "powder trick" in an attempt to rig a horse race. It is revealed that the horse is named "Monaghan Boy". He then returns to the Shelby residence for a family meeting. Upon learning that a new policeman is about to be stationed in Birmingham following the loss of a consignment of guns from the BSA factory, Polly Shelby takes Thomas aside and questions him on the matter. He reveals to her that his men accidentally acquired the wrong crate during a routine pick-up, instead taking a crate that contained Lewis machine guns, ammunition, semi-automatic rifles, and pistols with shells.
Seemingly heeding Polly's advice, Thomas says he'll dump the guns as soon as the full moon wanes, in the hope that the policemen won't pursue the matter further. After Arthur Shelby Jr. is forcibly taken to meet Inspector Campbell, and reveals that Campbell might want to work together with them to recover the missing consignment, Thomas, after a moment's pause, leaves the room without any further discussion of the matter. Some time after, as Curly and Charlie Strong (Thomas's uncle) are preparing to drop the guns off, Thomas changes his mind about leaving the guns for the police to find, and has Curly drop the guns off at the old tobacco wharf, where the Peaky Blinders keep contraband cigarettes—all in favour of some alternative strategy.
Later, it is revealed that the new barmaid at The Garrison Pub, Grace, is an undercover agent working to recover the missing guns, when she meets with Campbell. She then informs Campbell that the leader of the Peaky Blinders is not Arthur, but Thomas.
Thomas likes the snow aka cocaine but not as much as Arthur.
