The sound is gone. There's nothing left but the insomniac throbbing of crickets. Crickets in the garden, the courtyard, the back courtyard. Close, domestic, identifiable. And those out in the country. Between all of them they raise, little by little, a wall that will keep out the thing that lies waiting for the tiniest crack of silence to steal through. The thing that is feared by all those who are sleepless, those who walk through the night, those who are lonely, children. That thing. The voice of the dead. 
Rosario Castellanos, The Book of Lamentations
death, silence
