A murder mystery set in a clifftop house in three acts When a house party gathers at Gull's Point, the seaside home of Lady Tressilian, Neville Strange finds himself caught between his old wife Audrey and his new flame Kay.

A carefully unpeeled investigation before our eyes brings the story to a pointed ending. The play, by Agatha Christie and Gerald Verner, premiered in the West End at the St. James' Theatre in September, 1956 produced by Peter Saunders - producer of The Mousetrap.
