At forty, Wednesday Addams lives in disciplined solitude, consulting on cold cases from her crumbling ancestral estate. But when a distant relative dies under suspicious circumstances, she’s pulled into a chilling mystery that includes a veiled funeral guest, a forgotten masquerade, and a photograph that shows Wednesday somewhere she shouldn’t be—somewhere she doesn’t remember being. As she investigates her own missing time, Wednesday crosses paths with Felix Marron, a private investigator with grief of his own. Their alliance is slow, sharp, and reluctant—but essential. The deeper they go, the clearer it becomes: someone once tampered with Wednesday’s memory. And someone—perhaps Genevieve Thornhart—never stopped watching.
