Is it possible to put aside years of investigative instincts and habits to live quietly in a retirement home? Is it possible to redefine who you are at the age of eighty? These are the questions that Bess seeks to answer in Gumshoe Granny Investigates. When she arrives at the Honey Hills Retirement Center, Bess Bullock has every intention of occupying her days with simple activities like reading and idle conversation. However, Bess begins to notice that even at a retirement home, her instincts for noticing the 'little mysteries in life' won’t allow her to live as quietly as her fellow residents. Whether it is a thieving therapy dog, a philandering husband with a touch of dementia, or a baby’s cry in the middle of the night, Bess is drawn into each mystery with the same curiosity she had fifty years earlier as the first woman to work for her town’s police force.
