Three days before going missing, Ana Saura had recognised the man she had seen at Casa Castro, talking with Juan Elias on campus. Giralt learns that a colleague has interviewed the wife of a man who went missing on the same day as Ana and believes there to be a connection. Eva Duran keeps her promise to spend the day with Juan.
An injured and disorientated man arrives on foot at a petrol station, claiming to have no memory of who he is or how he got there. In hospital he is visited by his wife, who informs him that he is a prestigious lawyer, but far more ominously, that their 22-year-old niece Ana is missing and that her blood has been found in his car.
Aware that their previous relationship will compromise her ability to prosecute the case brought against Juan Elias by his brother-in-law Ramon Saura, Eva retreats to her grandmother's rural home. No-one is completely convinced of Juan's amnesia, including his partner Ricardo Heredia.
