Each card had a little handwritten note from her, a small message that I had always thought was just her “rambling grandma-isms.” They were cryptic, poetic sayings, like: “Not every door is locked just because it creaks,” and “You’ll never find truth where everyone agrees.” I used to think she was just being weirdly philosophical. But now, seeing them all together, I understood I was looking at something much deeper.
The real secret was hidden on the back of each card. She had used a different color of ink to underline certain letters—just one letter here, maybe two there—within her handwritten message. The shaking started in my hands as I spread all 17 postcards out on the kitchen table. It was a painstaking process, but I started carefully jotting down the underlined letters in the order they appeared on the cards.
