Susan Henshaw and her husband, Jeb, are the proud grandparents of beautiful twins, and their daughter and son-in-law are temporarily moving into the Henshaws' Connecticut home with their tiny bundles of joy. Added to the mix are two giant bullmastiffs and a nanny. Though a bit overwhelmed, Susan and Jeb are delighted to be a part of the chaos.
But a neighbor, Nadine Baines, soon starts to rain on their parade. She recognizes the nanny as a suspect in several recent shady deaths at a nursing home. The day after this troubling revelation, Nadine is found in her kitchen with a knife protruding from her chest. Is the nanny the culprit? Are Susan's grandchildren at risk? With murder so close to home and another possibly following, Susan must investigate-and she uncovers a tangled conspiracy beyond her wildest imagination.
