The post disappeared by morning, but I had saved a copy.

I stopped refreshing the group because every new opinion felt like another hand pulling at our front door.

Sophie asked whether I was afraid.

“Yes,” I said.

“Of what?”

“That we’re missing something we should have seen.”

“I think that’s what she wants,” Sophie replied.

The letter itself surfaced in a place none of us expected.

A town sanitation worker found a torn envelope in a public trash bin outside the abandoned train platform.

He noticed the embossed Sutton seal because his daughter played clarinet in the school band.

The envelope was damp, missing its contents, and smeared with coffee.

Instead of throwing it away, he placed it in a clean plastic sleeve and called the postal office.

Evelyn Ross contacted me after the item was logged and photographed.

She did not let me handle it.

She showed me the images and asked whether I recognized the handwriting on a line beneath the printed address.

It was my own name, but not written by me.

Somebody had added the words guardian copied in blue ink.

The letter had been opened along the top seam, carefully enough that a person could have read it before tearing the corner.

“Is there a way to know who put it in the bin?” I asked.

“The station camera might help, but we haven’t established when it was discarded.”

“Could it have blown there?”

“Possibly.”

Evelyn tucked the photographs away.

“I know you want certainty, Mr. Mercer, but it would be a mistake to invent it just because we have a piece of paper.”

I drove home thinking about the unseen person who had stood over our mailbox.

For the first time, I imagined that person feeling afraid too.

Sophie asked to see the photographs when I got home.

I hesitated, then showed her the image of the torn envelope.

She studied the blue words beneath my name.

“That looks like Paige’s handwriting,” she said.

“How would you know?”

“She wrote all the rehearsal cards at Celeste’s studio.”

I asked Sophie not to say anything publicly or contact Paige about it.

She agreed, though I could tell the restraint frustrated her.

Later she found a stack of old studio cards in her desk drawer and placed them beside the photograph.

The handwriting shared a narrow letter g and a distinctive upward curl on the last stroke of each word.

I sent photographs to Evelyn without claiming a match.
