Hidden so they can't be found

Safe within your cloak of sound, 
Blocking out the world around, 
Floating on angelic ground, 
Hidden where you can be found.
Standing here against the wall, 
Close enough to catch your fall, 
Waiting at your beck and call, 
Thinking how to make you stall, 
Creeping just a step behind, 
Always in my sights to find, 
Keeping you in heart and mind, 
Hoping you will act in kind, 
Stepping out into your life, 
Introductions with a knife, 
Walking now like man and wife, 
No one here to aid your strife, 
Leaving you my sacred mark, 
Putting out your angel's spark, 
Pretty eyes now cold and dark, 
A work of art so bold and stark, 
Safe within my cloak of sound, 
Thoughts of pain and death abound, 
Keeping them deep in the ground, 
Hidden so they can't be found.
