- Monocaine? What is monocaine?

- Monocaine's a terrible drug.

- I never heard of it.

- You wouldn't. It's never used now. I didn't know it was even made.

- It's a drug that's made from a flower that's grown in India. It draws color from everything it touches. Years ago they tried it for bleaching cloth. They gave it up because it destroyed the material.

- That doesn't sound terrible.

- Yes, I know. But it does something else.

- It was tried out on some poor animal... A dog, I believe. It was injected under the skin, and it turned the dog dead white like a marble statue.

- Is that so?

- Yes, and it also sent it raving mad.

- You surely don't think...

- I only pray to God that Griffin hasn't been meddling with this ghastly stuff.
