Posted on the entrance door of the Bathos apartment complex
[a sheet of unlined white paper, taped to the door at about eye level by a tallish woman with dark hair the morning of Nov. 1st. The top edge is slightly ragged as if something had been cut or torn from it, leaving the sheet slightly smaller than the average page. On the paper is a few lines written in a black ink, such as from a medium thickness felt-tip pen, in a neat long-hand written with a confident stroke.]
Slinky!
When you see this, contact me at ohmysweetgherkins@email.com. We need to talk.
I know it's been a long time since New York, so I'll understand if you don't want to see me, but, please, at least let me know you're okay.
[there is no name indicating who left it on the door, but there is enough information in the note that the correct recipient would know, or a particularly clever individual with enough clues could guess who it was for/was about.]
