Grace researches Christina and Alberto online. She discovers that Christina offered psychic services at Las Dalias market and that she had a brief singing career in the 1980s. She also learns more about Alberto, including his marine biology background, his publications about extraterrestrial life in the Mediterranean, and his diving company. Then, she discovers an image from the Port of Ibiza. The photograph depicts an “underwater meadow of seagrass” and her St. Christopher necklace lying amidst it (65).

Grace visits the local authorities and shows the Guardia civil officer Christina’s letter. The officer doesn’t think that the letter clarifies Christina’s death but insists on keeping it for his investigation. When Grace asks about Alberto, the officer warns her to avoid him.

Grace tries to forget the investigation and enjoy herself. She visits several of the locations that Christina recommended. Ibiza is beautiful, but Grace feels incapable of enjoying herself. She’s convinced that she’s a bad person who killed her son. She also feels guilty for having an affair with her colleague, Aidan Jenkins, and betraying Karl years prior. She tells Maurice that these are the reasons she’s been despairing but reminds him that every person has unique struggles and difficulties.
