Jody Hern's presumed fall has resulted in only one memory during her blackout (that of a man with a goat) and her promise to her sister, Estelle, her schoolmaster brother-in-law, Michael Page, and her fiance, Charles Vaughan, that she will try to forget. But her formidable Aunt Essie suggests she try to fill in the blanks -- and she finds the street, the owner of the goat -- and the man who has been leading it. Lt. Commander Desmond Huntley, on leave, helps Jody go further and they find a strange story in the building where Jody's accident had occurred that keeps Huntley eager for further investigating. But Jody is determined to shield her sister and Michael's school, until calculated terrorizing leads to murder and the answers to Jody's vulnerability. A smooth-running romantic adventuring, this should attract the Mary Stewart audience and please Cadell's own followers.
