The Sister on ITV, starring Russell Tovey, is a dark and spooky four-episode series which began the last week of October – just in time for Halloween.


The drama is stripped across four nights, and each episode has proven to be full of murder, intrigue, deception, haunted houses, the supernatural — and ghosts.

The Sister cast features Flesh and Blood's Tovey alongside a particularly creepy Bertie Carvel (Doctor Foster) as Bob, while the show is based on Luther creator Neil Cross' book, Burial.

The series focuses on Tovey's character – a man with a terrible secret who is (perhaps literally) haunted by the mistakes of his past. And given Cross' involvement in the drama, it's no surprise that we've been watching The Sister with our fingers over our eyes.

The Sister cast features Russell Tovey as the well-meaning but directionless Nathan, "a man with a terrible secret he’s prayed would stay buried and for which he’s worked hard to make recompense". Tovey has previously been seen in Years and Years, Him & Her, Being Human, The History Boys, and Flesh and Blood.

Joining him is Bertie Carvel as Bob, an "unwelcome face" from Nathan's past who "turns up on his doorstep with shocking news, triggering a series of catastrophic decisions which drive a tense and compelling narrative of psychological suspense, dread, love and possible redemption." Carvel's recent credits include The Pale Horse, Doctor Foster and Baghdad Central.

Further cast includes Amrita Acharia as Holly, Nina Toussaint White as Jackie, Paul Bazely as Graham, Simone Ashley as Elise and Amanda Root as June.

The Sister plot

The four-part murder mystery, written by Neil Cross (Luther, Spooks) and inspired by his novel Burial, follows a man attempting to escape the (potentially literal) ghosts of his past. Nathan is a well-meaning man who's spent years trying to atone for a terrible secret from his past, involving the disappearance of his wife's sister, Elsie (Simone Ashley).

However, a decade into his new marriage with wife Holly (Amrita Acharia) and Nathan is visited by Bob, a figure from his old life who is somehow connected with Elsie's disappearance.

Bob imparts shocking news to Nathan, resulting in "a series of catastrophic decisions which cleverly drive a tense and compelling narrative of psychological suspense, dread, love and possible redemption".

Earlier in October, exclusively revealed a first-look teaser clip from The Sister where we see we see Bob stare at a picture of Holly and her missing sister Elsie in Nathan's home before saying, "Nathan, what have you done?"
"It’s one of my favourite stories," Cross said when the show was commissioned. "A tale of psychological suspense, of guilt and ghosts and murder. Oh, and love. Always love. Our job is to make viewers want to sleep with the lights on. We're looking forward to it."

Is The Sister based on a true story?

For viewers wondering if The Sister is based on a true story, the four-part series is based on creator Neil Cross' book Burial, which in turn was inspired by a nightmare The Sister creator Cross had in 1985 about murdering a homeless man.

Speaking to and other press about the real-life inspiration behind the book, Cross also revealed that he himself had experienced a "haunting" – suggesting that the series will involve elements of the supernatural.
