Try to include these three random things:
A metal detector
“Things were much more simple when I was young and care free.
I always go back to that time before a kill.
I need the calm and peace it gives me.
That metal detector and I didn’t uncover many treasures, but together we went through countless adventures. I felt alive then.
I remember the day I found that shiny bottle cap. It was as bright as a diamond and filled me with joy. But that joy left me with my first kill forever out of reach with every subsequent one. Unfortunately, that’s all I am good at. Sometimes even too good. So, when it is time for another I reach out to that one memory, that one that gives me solace and makes my living out of a suitcase constantly looking over my shoulder bearable.
This mark, was as insouciant as all the ones before him. It will be quick and painless. I don’t like to make them suffer. When I am done, who will suspect that one of the heating contractors did it? Anyway, by then I will be long gone.”
