Ghosts.

You drag your feet on your patrol around your so called safe house.
For sets of eyes watching you as you do so. Three move around you unnoticed and with no sound, I stay, eyes on you like a lion stalking its pray.
I move along side you, watching you through the brush, watching and waiting for the perfect moment to strike. You light a cigarette and turn your back to me. With no sound, no warning you drop to the ground with a smile along your throat and find yourself swimming in a sea of red. And like the three ghosts before me I'm gone.
