It is a hanwritten note that looks like some kind of riddle.
I can't read it all but here's my best transcription job.
First think of the person who lives in disguise. Who deals in secrets, and tells naught but lies.
Next tell me what's always the last thing to (meet, med?) the middle of middle and end of the end.
And now give me the sound often heard during the search for a hard to find word.
Now string them together and answer me this which creature would you be unwilling to kiss?
I can't figure it out.
Hopefully the attachment works, so you can see the original. (edit, I guess the attachment won't work, it's a PDF)
