He was raving, Officer. Raving?

He was just raving.

When he was taken home he was delirious.

Big Jim was becoming delirious, hysterical.

Stupid babbling drunk. I'm sorry, Rupert.

Let the poor man rave. Don't give me your professional pity!

Many of them said, He has a demon, and is insane! Why do you listen to him?

And many of them said, He hath a devil, and is mad why hear ye him?

He remained unconscious, uttering incoherent phrases, until he died in the hospital two days later.

Vampires, according to eighteenth century science, were nothing more than the product of victims' delirium.
