Proctor pursues them by plane to Canada and Africa, and by car into the desert where he is stranded.

Constance is still grieving in the basement of Riverside Drive and is slowly seduced by Diogenes, while the surviving Agent Pendergast has been fished out of the sea by smugglers who want to use him to free a colleague from prison and plan to kill him afterwards.

Diogenes tells her that the incident on the volcano changed him and he is now working on two things: reconstructing the potion that gave Constance such a long life, and making her happy.

Her decision to leave is first hindered by a murderous attempt of her rival and then by the arrival of Pendergast and the FBI command units.

However, when Constance asks him to love her the way she wants him to, he declines and she leaves him to join her son in the far East.
