You will die by surprisewhen 
I take your life 
I will smile
John George 
Haigh was a vampirewho drank old ladies bloodthen put them in a non-corrosive drumand with acid he'd dissolve them
With my knife 
I make a cut on your neck
Your blood fills a glass for me
A special treat
Now that you're deadin a metal drum you'll stay
I pump the acid into melt your corpse away
