Dear Father Moran Anderson: Congratulations! Although you never smoked, you have been fortunate enough to be diagnosed with lung cancer at an age when your soul is still fresh. Unfortunately, your business of raising "Children of Hell" is not yet complete, and this Duke has been forced to invoke the "delayed death" clause.

I look forward to the day when I can personally harvest your soul. ———Lucifer, the Arrogant Duke, you are trustworthy...
