I Say Nothing Anywhere

I say nothing anywhere, I am silent
While you, as if my lord, order me silent
The story has something to say
But its characters are silent
Blame rains down
Yet, like a stone, I am silent
Till now the killer has been quite safe
Because the walls and doors are silent
People demand the killer's whereabouts
But the village guards are silent.
The same chained evening, same time of year
But why this time is everyone silent?
