Quote context

[...]

- We recognize your mastery of the occult sciences, but I can't permit your beliefs to interfere with my work.

- Then why did you send for me this afternoon?

- As a friend and an expert. Because I saw this find was unique, and I wanted your opinion on it.

- It is providential that you did.

- Come, Dr. Muller. Surely a few thousand years in the earth would take the mumbo-jumbo off any old curse.

- I cannot speak before a boy.

- Come out under the stars of Egypt.

- Do not touch that casket.

- Go on with your cataloging. We'll open it later.

- You needn't think you can persuade me not to examine the most wonderful find of my whole experience out here.

- If you're right about the legend, then this casket may contain the Scroll of Thoth from the holy of holies in the temple. And I can hardly wait to get back to find out.
