I Know, Do You?

I know a child, Who with vacant eyes, Sat looking at the door, Awaiting a man, To execute a plan, Her 'partner in crime' for sure. She kept staring, Grumbling and glaring, To hear the sound of her gate, But what came next, Was not the best, And her father was never late. He did return, But in an urn, Remains of a black coffin box, He gave his life, A supreme sacrifice, It was that family's loss.
