I took off my coat and examined the envelope under the light.

The attorney’s name was printed in the upper left corner.

Below it, in smaller letters, was an address I did not recognize.

The seal had not been broken, but the old file number was written by hand beneath it, separate from the return address.

I copied the number onto the back of the grocery receipt.

Then I turned the envelope over and checked the writing once more.

The ink had faded, but the last two digits were clear.
