A sleuthing library director is on the case when a patron drops dead in the tenth installment of Victoria Gilbert’s critically acclaimed Blue Ridge Library mysteries.

When a stranger falls over dead in the Taylorsford Public Library, clutching a crumpled piece of paper inscribed only with the words hen and sapphire, Library Director Amy Muir must once again investigate. She soon learns that the man is the personal assistant to Warren Sanderson, an art collector and dealer who just so happens to be visiting Kurt Kendrick, the godfather of Amy’s twins.

When the autopsy reveals that the library patron was poisoned, suspicion falls on those who knew him—mainly Sanderson, his granddaughter Heather, and Kurt. Determined to get to the bottom of the mystery, Amy digs into the contentious relationships between Kurt and the Sandersons. But as it turns out, suspects abound, and when Amy’s best friend’s boyfriend is implicated, the case becomes even more complicated.

Amy’s research ties the dead man’s note to a lost treasure of the Romanov empire. Then another person falls victim. With the bodies piling up, Amy knows better than anyone that killers often keep killing until they’re caught, and she’ll stop at nothing to get to the bottom of this tangled mystery.
