You sent a letter?I asked, confused.

“No,” Dad said, quietly.

“Then who did write it?“I sucked in my breath.

Dad reached into the pocket of his coat, took out a clear photograph and put it face up on my hospital blanket.

The picture was of a plain white envelope on the dark hardwood floor, right next to the bottom stair of my house.

The edge of the paper was a little smudged, but the name was perfectly legible.

Rachel Callahan.
