Every day in any country, in any city, people disappear. Disappear into darkness. No one, including the police, knows why, does not understand how this happens. And soon almost everyone will forget about these missing. That's it, but not Mila Vazquez. Seven years have passed since the events described in the "Tip," but the darkness does not let go of Mila, she leaves traces on her skin, perhaps because the roots of evil stretched to her soul. Remembering the disappeared is her job. These people look at her from the walls of the Hall of Lost Steps.
