Dear potential guest,
I am Mr. Hollow, Head of Service here at the Estate of Dr. Ambrosia. I write to you to provide a cordial invitation for an evening of puzzling hospitality and whimsical cooperation!
Seeing as I have the house to myself, I’d like to challenge you and your friends to solve a most precarious quandary. If you believe you possess the ability to best me, I eagerly await your reservation.
The man cocked his head to the side and spoke into his radio...
Sincerely,
Mr. Hollow
