Sometime after Colonel Arthur Bantry dies of pneumonia, his wife moves into a cottage on the estate grounds and sells Gossington Hall to film star Marina Gregg, who takes up residence with her husband Jason Rudd. At a fête hosted by Marina, St John Ambulance helper Heather Badcock drinks a daiquiri and subsequently dies. The coroner reveals Heather died as a result of ingesting four grains of the antidepressant Calmo, a quantity six times the recommended dose.
Shortly before her death, Heather was in conversation with Marina, giving her a long, boring account of how she had met Marina many years ago in Bermuda, getting out of bed despite her illness and putting on lots of makeup, to seek Marina’s autograph.
Marina is seen with a “frozen” look on her face for a moment while Heather talks to her; it is a look likened to the Lady of Shalott, as though “doom has come upon her.”
It then comes to light that Marina had handed her own drink to Heather after Heather’s was spilled. Therefore, it is surmised that Marina must be the intended victim. As a famous star who has married five times, she is a far more likely murder target. Suspicion is cast on many people, including Marina’s seemingly devoted husband, a big-shot American TV producer who is a former admirer and an American actress who was previously Marina’s rival in love (both Americans turn up unexpectedly at the party). A photographer at the party is actually one of three children Marina had adopted in the past for a while and then “got tired of” (Marina does not recognise her as such at the party).
