Foreign Rights

When I went to pick my mother up at her workplace, I discovered she had disappeared. Just in front of her computer, which was still on, six piles of sand and earth of no more than three centimeters high, aligned at an exact and equal distance between them. Seven miniature mountains are my only clue. I am not scared. I am angry. I will do whatever I have to. Someone has taken my mother away and they will regret having done so.
