Seven months after our divorce, I rushed into St. Jude’s Children’s and Women’s Hospital, still angry at my ex-wife, only to learn that she had just given birth to twin boys, and both of them were mine. Before the night was over, a nurse would place a brass key in my hand and tell me to use it before my own family arrived. And what was waiting for me beyond that was even more shocking.

It showed me as a twelve-year-old boy standing proudly beside my grandfather at the edge of the estate garden.

The silver frame had been moved carefully, without any damage at all.

I picked up the frame and set it upright.

Tucked neatly into the wooden backing behind the glass was a small white index card.

I pulled the card out and held it up to the dim light.

Three simple words were written in my grandfather’s neat, narrow handwriting:

Roots remember doors.
