Did anyone find a paperback with a green cloth bookmark?

What would you want to know first? It is a thin paperback with a cracked spine, a green cloth bookmark about halfway through, and pencil notes in the margins in small slanted writing. I lost it last Friday afternoon somewhere near Saraswati Temple, probably on a bench or a low wall. It matters because the notes are the only record of a long conversation I have been having with a friend, one margin at a time. I will check this board again on Sunday.
