Peaky Blinders: The Worst Thing Each Main Character Has Ever Done

7. Polly Shelby - Telling Hughes About Tommy's Plan

Polly Shelby - played so brilliantly by the mighty, late Helen McCrory - isn't just the second in command to the Shelby company, she is also the most trusted advisor to Tommy.

The bond the pair have is one of deep and unmoving trust, even when they disagree and don't speak, they still are able to somehow retain the ties that bind. Polly was a surrogate mother to Tommy, Arthur, John, Ada, and Finn - so her worst action was one that wasn't made out of spite, it was made out of ignorance.

In trying to confess her sins, Polly gets incredibly drunk and tells Father Hughes about Tommy's plan to kill a man of the cloth. Polly has no idea that Hughes is the man that Tommy is going to kill, or that he is the one giving all the information to the Russians.

However, because of her stupidity, her actions lead to Charlie Shelby being kidnapped and Tommy almost losing his wife and son inside a matter of weeks.

Charlie is rescued in the end by Michael, and no harm does befall the boy, though the actions that the rest of the family have to undertake in order to get the job done are heinous, which is all caused through Polly's ignorance.
