"Why, about Pan, I should presume," he says. "About John McCarthy, also? And likely the Ripper, oh my yes. And poor, sweet, dear Mary. Oh, yes. Mary was a special one, she was. But one cannot rewrite the past, can they? One cannot see what... course a woman's actions may take. But at any rate, I assure you men, you will thank us for what we do here today. Pan will change things. For the better. While you may see only the beginnings of that, Inspector, Baron, Doctor, certainly your children, and your children's children will look back and thank us.
"The early details of my life are of no import to you, and too painful for me to recount. But it was then I began to read Spinoza and some of the Greeks which influenced him. Nature is God, they said, and an extremely powerful one it is. I developed then the beginnings of my current interests. It was 1817, then, when first I arrived in England from France. I set up a medical practice in... Fleet Street, I believe my first was. Then I moved to the London Hospital, and gave several lectures at Oxford and Cambridge.

"Gorgo is, ahh, indisposed at the moment, you may find," she says. She takes a seat beside the door and places her finger on her chin. "You know, Nystor, it seems to me that your role in Hawksmoor's plan has been written out. You have served your purpose here."
"My role, Sosostris, but your interpretation of the role. I must still be here to guide it, to help it take the proper shape."
"There is your first mistake, Nystor," she says, rising. She draws a pistol and levels it at him. "Not Sosostris. Tera. Finally I have a name again. A name, and my own plans. Plans which do not include you!" There is a crack as the pistol is discharged and a crimson stain blooms on Ferencz's jacket. She smirks at Dr. Hewitt as he rushes over to Ferencz. "What did I tell you men? An unexpected turn of events." She points at a spot in the shadows along the wall and vanishes.
