Story
As Lara and Sam attempt to get back to their previous life, it is clear that both are having trouble adapting to life in the everyday world of their London flat. Lara suffers from anxiety, flinching at noises and having panic attacks. The situation becomes more complex as the hospital phones Lara, telling her that Sam has suffered an overdose and has allegedly attempted suicide, Leaving a note for Lara:


 * "Dear Lara,


 * My very best friend!


 * It's all too much!


 * I know that you understand. you were there. I don't think that I can bear it any longer. You saved me once, but I don't believe that I can be saved again. I don't think I can be saved from Her. It isn't your fault. Know that I don't blame you. I just can't live with what happened at Yamatai.


 * Your true friend through all eternity,


 * Samantha Nishimura."

Lara stays with Sam at the hospital, but unfortunately her friend seems only to refer to herself as "Himiko". Lara panics and returns home, looking for help from "The Book"; a historical log book which had passed hands many times before coming into her possession. After research, she discovers the legend of the Golden Fleece and seeks help from her father's friend Professor Cahalane. He refers her to a professor of antiquities at Oxford, St. John Babbington, whom she arranges to meet. On her way, she feels suspicious of being followed on her train, and befriends a group of students.

At her meeting with Babbington, she discovers that the fleece legend derives from an old method of gold panning with fleece in Colchis. He then invites her to attend relevant lectures for the week. After taking him up on his offer and attending the lectures, she meets a post-graduate American student called Kennard Montez, who is researching Colchis. She spends more time with him to find out more about Colchis and the fleece myth. He refers her to a man in Paris who may be able to help uncover the secrets of the Fleece, and she embarks immediately.
