Mysterious Parcel

Boss, I have a package for you. The messenger who delivered it, there was definitely something strange about him. I can swear I saw smoke rising up from his hood!
He shoved me the parcel and muttered that he'd be back next week. And he told me to pass it to you immediately, and then he just disappeared, I swear!
So I have no idea who the sender is.

If this messenger show up again the next week, I won't let him go away this easy. I'll ask who he is and what he's up to! Have to keep all my eyes about him, though, or he’ll flee in a wink again!
