It fans out in every direction, like shrapnel. It embeds itself in the skin of the little victims of your crime; your bereavement, your divorce. By killing one you remove both. And so there are orphanages and runaways and anti-social services.
The shrapnel not extracted runs inside them, so they will always piss blood when they piss.
And nineteen years later they might feel less diminutive, and twenty little years later you are free from good behaviour. You arm yourself with a shovel. You dig up the corpse, sully the crime scene. You haunt the little victims of your crime.
