Helen McCrory's Polly Grey (Shelby) has become one of the most sought after characters on BBC One's 'Peaky Blinders'. Polly is the matriarch of the infamous Shelby family who rules over Small Heath, in Birmingham. Polly's three nephews, Arthur Shelby (Paul Anderson), Thomas Shelby (Cillian Murphy), and the late John Shelby (Joe Cole) lead the notorious street gang, Peaky Blinders, who are known for slashing the eyes of their enemies with razors attached to their caps. While her three nephews take care of the Shelby Automobile Pvt. Ltd's external affairs, which often involve murder, theft, and robbery, Polly is the company's treasurer. 

In a recent shot of her from the set of Season 5, uploaded on Instagram, the matriarch can be seen posing in front of what seems to be a Wolseley 21/60 County de Luxe car. She is clad in a shirt with a tie, a waistcoat, and a suit, and she sports her curls with a hat. Polly Grey completed the attire with a pair of gloves and shades, as she casually leaned against the car.  The picture immediately drew fans' attention some of whom even compared the character's look to Marlene Dietrich, the German-American actress whose stunning appearance and skillful performance in silent films made her the highest paid actress of the early 20th century. "Is she channeling Marlene Dietrich? Such queens."

Fans are even more impatient now about the show's release date so that they can tune in at just the right time to catch up on what Polly Shelby might be up to.  One fan commented, "Please just give us a release date already :(." Another fan commented, "I know, right? Stop teasing us and bring on the show!" Some fans admired Polly's look as they said, "Femme Fatale and the Matriarchal type who happens to have ice in her veins... I love her character." Some are even claiming that probably the Shelby family has got even richer ever since Thomas was elected a Member of Parliament, after becoming the Communist party leader, in Season 4. "I can see series 5 being quite polished...There’s a lot more money in the pot... ".

Polly's character has been one of the most interesting developments on the show. She started off as an almost-mother figure of the Shelby brothers, whose child was snatched away from her at birth. However, once Polly was told by Thomas that her son, Michael, was alive and he had met him, Polly sort of lost her ground. Throughout season 3 Polly struggled to maintain her sanity as she begged Thomas to help her reunite with Michael. However, she gained back her position as the matriarch once she reunited with her son. Season 4 saw Polly reclaim her place in the business, and spearhead several of the Peaky Blinders' operations. 

Wonder what more is Polly Shelby up to in Season 5, which is set to return on BBC One in Spring this year.
