Towards Zero by Agatha Christie

When a house party gathers at Gull’s Point, the seaside home of Lady Tressilian, Neville Strange finds himself caught between his first wife, Audrey, and his new wife, Kay. A nail-biting thriller, the play probes the psychology of jealousy in the shadow of a savage and brutal murder. The investigation unfolds before our eyes and brings the story to a pointed ending. “A double parlour game – before guessing the killer’s name, we are invited to guess who is going to be killed.”
– Kenneth Tynan, The Observer
“An evening in which we do not smell a rat until too late.” – The Times
