In 1976 in New York City, Gina Engel was murdered in her front hall. The police believed the victim had known her attacker. But they had few suspects, and as time went on, the case remained unsolved. Yet the suspicions of those who knew Gina both intimately and from a distance continue to plague them. Gina's son, Steven, discovered the body and caught only a fleeting glimpse of the killer as he fled. If only, he wonders again and again. As Lily Chin prepares for her upcoming wedding, her life is irrevocably changed when a mysterious woman appears to inform her of her fiance's secret life - a life that may have included Gina Engel. And more than a decade later Louise Carpanetti, the woman who received a call from the dying Gina, finally acknowledges that her own emotionally disturbed son may have committed the gruesome murder. As long as the murderer's identity remains a mystery, all three must forever call into question the nature of the people closest to them.
