The pair were subsequently married and fled the city but later returned when the communist decided he didn’t want to be afraid of the Shelby brothers.
In the opening of series one, episode four the pair are seen returning to Birmingham on a boat but one eagle-eyed fan spotted a plot hole with this scene.
On a Peaky Blinders forum, the fan said: “When Freddie and Ada return to Birmingham from London they are seen on a boat called Kennet.
“This is a wide boat, almost twice the width of a seven-foot narrowboat, which could not have made its way from London to Birmingham in 1919, 1920 as all of the locks were narrow locks at that time.”
