I think it's "My dear Cora, this little..."
"Cora" is a fairly common woman's name, and commoner in the past when this might have been written.
The word "little" is puzzling but I think it's a kind of error common when handwriting. I don't think it's "title" because it would be an unusual word to find in this context, and because where the crossbar is written. Notice, too, that the writer neglected to dot the "i" (or is that an intentional "ligature?")
