Gravestones

An undisputedly perfect flaw of the flow blows
The rhyme moans as the time gradually slows
From its furry crown to the claw, a tiger shows
A true king’s disposition and it never bows
LD50 lethal injection of a golden shot overdose
As its shadow proudly strikes a superhero pose
Secrets dig their graves and buried their bodies
But the soil can’t cover the truth, it still crawls 
At the back of your consciousness it still prowls
