Gloria Lamerino's goddaughter, Mary Catherine Galigani ("MC" to her friends), needs a change in her life. She decides to move back to her hometown of Revere, Massachusetts, thereby ridding herself of both an abusive relationship and an unfulfilling job in Houston, Texas. At least that's the plan.
When two homicides disrupt MC's peaceful return to Revere, Gloria applies her not inconsiderable detecting skills to help the police solve the crimes. At the same time, Gloria must face the medical problems of her partner, Detective Matt Gennaro, and the next steps in their relationship. In this sixth periodic table mystery, Gloria delves behind the scenes into the worlds of nanotechnology and show horses, and unwittingly uncovers a crime ring larger than the distance between Texas and Massachusetts.
