Portrayed by Stephanie Beacham, the character was introduced on Dynasty in the November 1985 two-part episode "The Titans" as the socialite wife of wealthy California CEO Jason Colby (Charlton Heston).

[3] Faye Dunaway, Angie Dickinson, Elizabeth Ashley, and Diana Rigg all turned down the role of Jason's wife Sable.

[5] In August 1985, producers cast Beacham, "a household name" in the UK who had starred in the title role of the ITV drama Connie.

[6] On vacation after playing a ruthless businesswoman on Connie, Beacham almost passed on the request that she return to London to screen test for The Colbys.

[13] The Colbys of Los Angeles come to Denver to celebrate a new business venture with oil tycoon Blake Carrington (John Forsythe) in the 1985 Dynasty episodes "The Titans - Parts 1 and 2".

Sable is the wife of mogul Jason Colby, and the mother of his three children Miles (Maxwell Caulfield), Monica (Tracy Scoggins), and Bliss (Claire Yarlett).

A dismissive Jason tells Sable to stay out of it, but she makes a failed attempt to convince Constance that she has made a mistake.

In "Conspiracy of Silence", the Colbys are surprised when Miles comes home married to Randall, who they now know is an amnesiac Fallon Carrington (Emma Samms).

She is reunited with her estranged sister Francesca (Katharine Ross), Jeff's mother with Jason's deceased brother Philip, but makes it clear she hopes Frankie will not stay in town long.

Sable comes across Jason's medical report and is shocked to learn that he is dying, unaware that his doctor has told him the diagnosis was a mistake.

Sable learns of Constance's secret boyfriend Hutch Corrigan (Joseph Campanella), and mistakenly comes to believe that he is a con man extorting money from her.

In "Burden of Proof", Sable is shocked to hear Jason claim to be Jeff's father in court, and vows to never forgive him.

In "A Family Affair", Sable remains unable to convince Constance of her good intentions, but manages to ingratiate herself to Jason by offering concern for Jeff, who has also been arrested for murder.

Leaving for Greece to investigate Jeff's case, Jason and Frankie are joined by Sable, who has invited herself along for moral support.

Sable is terrified when it seems like Miles has jumped bail, and when he reappears she makes it clear she is willing to lie in court to give him an alibi.

In the season two premiere "The Gathering Storm", Sable refuses pleas from Frankie and Miles to drop the charges against Jason.

Despondent, Sable asks Monica for advice, and confesses that she lied to the police about Jason and now wants to drop the charges.

Taking Arthur's advice, Sable drops the charges and, to avoid legal repercussions, pleads temporary mental incompetence brought on by her shooting.

While investigating Channing's fertility in "Bloodlines", Sable inadvertently discovers that the paternity of Fallon's child is uncertain, and deduces that the father may very well be Miles.

In "Bid for Freedom", Sable helps convince Jason to assist Bliss's Russian ballet dancer boyfriend, Kolya Rostov (Adrian Paul), in defecting to the US.

In "The Manhunt", Sable tries to convince Cash and Monica that Scott will be better off away from Adrienne, who has had addiction issues and made suicide attempts.

After witnessing Monica's heartbreaking goodbye to Scott, Sable picks the boy up from school without the Cassidys' consent and persuades him to come with her.

Alexis is there to meet with Sable's wealthy friend Hamilton Stone (Christopher Neame) to aid her in recovering her ships, which are being held in the African nation of Natumbe.

Sable tells Blake he has her support if the story comes out, as the dead man is Roger Grimes (J. Eddie Peck), Alexis's lover from 25 years before.

Sable and Dex flirt after they each independently follow Colbyco's comptroller, Fritz Heath (Kenneth Tigar), to a casino.

Blake accuses Sable of acting on her ex-husband Jason's behalf, but before she can explain, Alexis arrives and vows to destroy them both.

In "Virginia Reels", Sable tells Blake and Dex she was searching the lake to discover what Jason was keeping hidden there.

Jealous of Dex's interest in Sable, her assistant Joanna Sills (Kim Terry) befriends Adam Carrington (Gordon Thomson.

Blake confesses to her and Dex that hidden beneath the lake is a Nazi treasure of precious art innocently obtained by his father which the Carrington, Colby, and Dexter families have kept secret to protect their reputations.

Having learned about the Nazi treasure, Alexis offers to spare Blake public scorn in the series finale "Catch 22" if Sable withdraws her lawsuit against Colbyco.
