My name is Margaret Elaine Caldwell. I was 76 years old when the ground beneath my feet began to shift. Harold was 78. We had three children, our son Douglas, who lived in Phoenix with his wife Renee, and our two daughters, Patricia and Susan, both in the Boston area. Six grandchildren between them. Every Thanksgiving, the house smelled like cornbread and cinnamon. That was the life I knew. That was the life I thought was permanent.

The first sign came on a Tuesday in late October. I remember because the leaves had just peaked, that particular orange and gold Connecticut does better than anywhere on earth. I had gone to the pharmacy to pick up Harold’s blood pressure medication and mine, and the pharmacist told me Harold had called ahead to change the billing address on his account. Not ours. His. A post office box in Westport I had never heard of.

I told myself it was a mistake. Harold was forgetful. He was 78. These things happen.
