After Aggie Dunkirk's career is unceremoniously ended by her own mistakes, she finds herself traveling to Wisconsin, where her grandmother, Mumsie, lives alone in her vintage, though very outdated, home. Aggie didn't plan for how eccentric Mumsie has become, obsessing over an old, unsolved crime scene—even going so far as to re-create it in a dollhouse.

Mystery seems to follow Aggie when she finds work as a secretary helping to restore the flooded historical part of the town's cemetery. Forced to work with a puzzling yet attractive archaeologist, she exhumes the past's secrets and unwittingly uncovers a crime that some will go to any length to keep hidden—even if that means silencing Aggie.

Unfamiliar with the burgeoning world of forensic science and, as a woman, not particularly welcomed into the investigation, Imogene is nonetheless determined to stay involved. As her sister's case grows cold, Imogene vows to find justice . . . no matter the cost.
