Set in 1936, the series follows British tennis star Nevile Strange and his ex-wife Audrey, who decide to spend the summer together at the coastal estate of Nevile's aunt, Lady Tressilian, despite their scandalous divorce. But with the sportsman's current wife also present, tensions are running high.

The synopsis continues: "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 (World on Fire, Ripper Street) teased the show as a "disturbing tale of truth and lies, love and hate". "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," she said in a statement. "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."

Meanwhile, director Sam Yates (Magpie) added: "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."
