Meg loved the beautiful butterflies that frequented her garden. Her narcissistic husband, Lyle, enjoyed them even more when he could trap them. He would watch the poor creatures slowly suffocate to death in a preserving jar while his wife looked on in horror-and then he pinned them onto a display board. After years of physical and mental battering, Meg freed a precious, blue butterfly and smashed the jar. Her tormentor forced her to the ground to pick up the shards of glass while he stood over her. Afterwards, he made her accompany him on their regular Friday night fishing ritual, forcing her to carry all his fishing gear to the Heads-a dangerous fishing spot. But that day, when a rogue wave swept Lyle into the sea and he disappeared, Meg froze, standing on the rocky ledge, unable to help him. It was his life versus hers, and she turned away and walked home. Suffering from clinical amnesia when under stress, she later couldn't remember if the fateful event actually happened. If he had drowned, was she capable of being a cold-blooded killer? The detective, Ann Grieves, offers to help Meg unravel the turmoil in her brain-but will she ever be ready to accept the truth?
