Mr Selfridge is back for a fourth and final series, jumping forward nine years to 1928. A slightly greyer Harry Selfridge remains at the helm of his Oxford Street store but his weakness for women and gambling is beginning to clash with the running of his empire. Will the return of Katherine Kelly's Mae keep Harry grounded or will the gold-digging Dolly sisters tempt his wandering eye? We'll no doubt find out over the course of the final ten episodes. But first, meet the cast...

Familiar faces

Harry Gordon Selfridge (Jeremy Piven)

A decade since the death of his beloved wife Rose, Harry is looking rather lost. Painting the town red till the wee hours surrounded by booze, gambling and hangers on who need to be bankrolled, the Selfridges boss is beginning to lose his control on the business he built from scratch – and worrying the women who care about him most.

American actor Jeremy Piven is best known for playing obnoxious agent Ari Gold in hit US series Entourage – a role that won him a Golden Globe and three consecutive Emmy Awards. He's also appeared in more than 50 films, including Serendipity, Spy Kids and last year's Entourage movie.

Mae Rennard (Katherine Kelly)

Mae is back from Paris, licking her wounds following a second divorce. Her French husband has gone off with another woman and poor Mae is left penniless, arriving on Harry's doorstep to sell her Selfridge's shares – before Harry offers his old friend a helping hand with a job at the store.

Katherine Kelly played Coronation Street's Becky McDonald for six years, before quitting the cobbles in 2012. She's since starred in a string of acclaimed dramas including Kenny Everett biopic Best Possible Taste, The Guilty and The Field of Blood, plus a spell on stage in She Stoops to Conquer. She'll next be seen in series two of Happy Valley and the BBC's adaptation of John le Carré's The Night Manager. 

Rosalie de Bolotoff and Violette de Sibour (Kara and Hannah Tointon)

Series four finds Harry's eldest daughter Rosalie at home in London with her nine-year-old Tatiana while her husband Sergei works oversees. Her sister Violette, meanwhile, returns to London after living in Paris with her aviator husband Jacques de Sibour. 

Real-life sisters Kara and Hannah Tointon first made their names in soaps. Kara played Dawn Swann in EastEnders between 2005-2009, and has since appeared on Strictly Come Dancing, winning the show's eighth series, and played Maria in ITV's Sound of Music Live! last December. Hannah came to attention as Katy Fox in Hollyoaks between 2007-2008, going on to appear in The Inbetweeners, The Hour and Death in Paradise. 

Mr Grove (Tom Goodman-Hill)

Selfridges' chief of staff has a busy life at work and at home as a single father to four unruly children. We last saw him reuniting with head of fashion Josie Mardle, but there was no happily ever after for the unhappy pair and she's since moved to New York to start a new life.

Trystan Gravelle began his career on the stage, spending three years working for the Royal Shakespeare Company, before landing his first screen role in 2011's Anonymous opposite Vanessa Redgrave and Rhys Ifans.

Frank and Kitty Edwards (Samuel West and Amy Beth Hayes)

These two are going up in the world, enjoying the comforts of a lavish new pad, but with Frank acting as Harry's right hand man (a role that sees him frequent London's hottest nightspots) the couple don't see much of each other and Kitty's looking rather lonely...

Son of Timothy West and Prunella Scales, Samuel began his career with a Bafta nomination for 1991 film Howard's End. He's since appeared in films Notting Hill, Iris, Van Helsyng and Hyde Park on Hudson, as well as TV series Cambridge Spies, Any Human Heart and Jonathan Strange & Mr Norrell, plus a string of stage roles. Amy Beth Hayes made her screen debut in Doctor Who and has been in TV series Whatever It Takes, Misfits, The Syndicate and Black Mirror. 

Miss Mardle (Amanda Abbington)

Last seen in the arms of her former lover Mr Grove, Miss Mardle is nowhere to be seen at the start of series four after packing her bags to begin a new life in the Big Apple. Will she find her way back to London before the series is out?

During her two decades on screens, Amanda Abbington has enjoyed a successful TV career, including roles in Case Histories, Married Single Other and Cuffs, although she's best known for playing Mary Morstan in Sherlock opposite real-life partner Martin Freeman.

Gordon and Grace Selfridge (Greg Austin and Amy Morgan)

Series four finds Gordon managing the regional branches of Selfridges but yearning to be working in London's flagship store and back in his father's good books. At least he has a happy home to return to with wife – and former shopgirl – Grace and their two children.

Amy Morgan has acted in TV series Baker Boys and The Great War: The People's Story, and has trodden the boards in Hay Fever and The National Theatre's The Beaux' Strategem.
