'Bill Morrow is a middle-class Australian, an insurance investigator and assessor who usually knows the score and suspects everyone until proved innocent. He is asked to go down to a remote seaside pub with Sally Mears, who has just received a letter from her wealthy sister Anne, asking her to bring to the hotel a valuable diamond bracelet.
'What mystifies Sally in the letter is that “bracelet” is spelt correctly and not “bracelette,” as Anne would normally have spelt it, for she never could spell. Sally fears foul ploy. Morrow arrives at the hotel, with its unusual mural paintings, and is told that Anne has gone, her little daughter Janet with her. Then Anne, plainly frightened, is seen mysteriously about the hotel, wearing the expensive bracelet. It is Sally who has now disappeared.'
