- John? You must excuse me, I... I've been unwell, you understand. My memory...

- You look well, Son.

- I am well, thanks.

- Your leg, what's the matter with it?

- Oh, I... I damaged it three years ago. It didn't mend very well.

- Oh. You should have seen a doctor and had it set.

- You wanted to see me, Father?

- Oh, yes.

- The mummy. I wanted to tell you about the mummy.

- The mummy?

- From Ananka's tomb.

- Oh, she's in the British Museum, sir.

- Not the princess, not her. It was the mummy who lives.

- I'm afraid I don't... I don't understand.

- The mummy I brought to life when I read the scroll.

- There was no other mummy.

- Don't talk rubbish, man, I was there, I saw it myself. It came from the rock when I read the scroll.

- What scroll?

- The Scroll of Life. After 4000 years, the words of the scroll brought him to life again.

- It hates us, John. It hates us for desecrating the tomb of its princess. It will kill us! It will kill us, all of us!

- Father, you mustn't upset yourself. Stop thinking about it. Nothing really happened that day, you know?
