The three neighboring houses on Maine's seacoast seemed lost in the fog, cut off from the rest of the world. The houses belonged to Vera Waters, her aunt--and now there was a strange new family, who came shrouded in mystery as deep as the fog. Who were the Harpers? Just two men and a woman who, as they claimed, liked the area? If so, why did their first sight of Vera shock them into near silence? And why did Aunt Samantha's astrological readings, usually happy and frequently correct, warn Vera of impending danger?

The threat to Vera's sanity and life became brutally clear the day a private investigator arrived in town. One of the Harpers, said Detective Egan, was mad, haunted by an ancient murder--and driven to kill again! Vera, equally compelled, found herself the unwilling bait in a trap more terrifying than her worst imaginings!
