When an unexpected message requires Maggie to finally go through long-ignored boxes from her late husband’s archaeology lab, she discovers more than just priceless Native American artifacts in her storage room. Instead, she pries open a years-old mystery that casts doubt on her beloved Richard’s intentions — and even his integrity.

Hesitant to open the proverbial Pandora’s box, Maggie distracts herself with preparations for the town’s History by Candlelight Tour and tries to delay her investigation of the crates’ contents until after the event. Unfortunately, someone else is in a much bigger hurry to unpack the past, and Maggie becomes a target for increasingly frightful encounters. As the alarming incidents pile up, Maggie starts questioning the motives of even those closest to her.

Not knowing where else to turn, Maggie enlists her friends at the historical society to get to the bottom of the confusing cargo. Can she bear it if the results of their research cast Richard in a poor light? Will knowing the truth about these puzzling packages help her get the closure she seeks — or will it upend her fragile life in unimaginable, and potentially disastrous, ways?

This is one mystery Maggie must handle with care . . . or else.
