Shirley Duffield is on holiday at her grandfather’s cottage beside the sea. She becomes fascinated by Mavora, a rock that looks like a mermaid combing her hair and beckoning. Legend has it that Mavora has lured many seamen to their deaths, and Shirley is now hearing strange voices that come from the direction of the rock. Then Shirley finds a comb that suggests that there may have been a real mermaid.
