Casting and characters are confirmed as: Lady Tressilian (Anjelica Huston), Inspector Leach (Matthew Rhys) and British tennis star Nevile Strange (Oliver Jackson-Cohen) – seen here with the two ladies in his life: ex-wife Audrey (Ella Lily Hyland) and new wife Kay (Mimi Keene). Clarke Peters, Anjana Vasan, and Jack Farthing are also seen in the new pictures from the series, which co-stars Jackie Clune (Motherland), Grace Doherty (Call the Midwife), Khalil Gharbia (Mary & George), and Adam Hugill (Sherwood).

The plot is set in England, in 1936. After a scandalous celebrity divorce, Nevile Strange and his ex-wife Audrey make the unthinkable decision to spend a summer together at Gull’s Point, their childhood home and the coastal estate of Nevile’s aunt, Lady Tressilian.

With unfinished business between the former childhood sweethearts, plus the presence of Nevile’s new wife Kay, tensions are running high. Add to this a long-suffering lady’s companion, a mysterious gentleman’s valet, an exiled cousin with a grudge, a venerable family lawyer, an inquisitive orphan and a French con man, and soon there will be murder. A troubled detective must rediscover his purpose to untangle a toxic web of jealousy, deceit and dysfunction. Can he solve the crime before another victim meets their death?

An explosive love triangle, a formidable matriarch and a house party of enemies. All compelled… Towards Zero.

Writer, Rachel Bennette, says: “These are among the richest and most complex of Christie’s characters, and I was captivated from the first by the charisma, in particular, of her female characters. It has been thrilling to bring them all to life in this disturbing tale of truth and lies, love and hate, a story which unfolds amidst the dark, cinematic glamour of the 1930s, yet feels startlingly of our time.”

Director, Sam Yates, says: “It has been an honour to bring this most psychological and sensual of Agatha Christie’s stories to vibrant life with a peerless cast of actors and an extraordinary team. Audiences are in for a propulsive, intoxicating ride into the dark hearts of some of Christie’s most irresistible characters.”

Towards Zero follows 2023’s hit Christie adaptation Murder is Easy, which was one of the UK’s most watched dramas of last year across all channels and streamers, averaging 7 million viewers across both parts.

Adapted for screen by BAFTA-nominated Rachel Bennette (NW) and directed by the Olivier Award-winning Sam Yates (Magpie), Towards Zero is made by Mammoth Screen and Agatha Christie Limited for BBC iPlayer and BBC One.
