The Demand

I'm calling you on a very secure line, Your problem last night I did coldly remove. She died among so many more innocents, Of my methods you would never disapprove. They died as if the work of a serial killer, The true target blended in with many another. Keeps the cops guessing and sorry to inform you, One that I murdered was your very own mother. But I still demand my remaining payment, After this sadness you're now going through. If not I will simply murder your wife, And after her I will easily come after you.
