From the cover, format and illustrations to the hokey writing style and gratuitous incidents, this is the sort of mystery you'd expect to find on the drugstore rack. It begins when Kevin (with ""bright and eager eyes""), his sister Christie (swirling ""honey-blond"" hair), and their mother Mrs. MacAlistaire (her eyes ""twinkle"") arrive at the Oregon cottage where they're to spend an ocean holiday. A girl named Mora tells the children that the next house, on its own cove, is inhabited by a witch (who plays her flute on a rock in the sea) and haunted by ghosts of sailors drowned by the vengeful magic of the witch's ancestor. Mora fills their heads and these pages with a lot of other claptrap, but though Kevin and Christie themselves observe the flute-playing witch, who seems to have three green eyes and the power to turn people to rocks, it turns out that she's an innocent lady being held captive by a pair of bank robbers. Kevin and Christie brave high tides, sheer cliffs, and a cave containing a dead sailor's bones to save the green-eyed lady (the third eye is just a jewel on her forehead) from the desperate gunmen, whereupon their parents arrive from a concert with guest soloist Zogrodzky in tow and more surprises: ""Mr. Zagrodzky was as horrified as the MacAlistaires to learn all that had happened in the haunted cove, for the green-eyed lady was his wife."" Like Mora said, it's best to avoid The Haunted Cove altogether.
