I'm halfway through The Mummy by Anne Rice. I predict I will have nightmares tonight.
Ramses just tested the powers of his immortality potion on a severed mummy hand. Imagine, if you will, a shriveled, dry, blackened claw transforming to a fleshy, pink, human hand. Then it begins scratching at the table. Oh, and it's immortal, so you can't kill it. So you chop it up with a knife and the pieces begin to bleed, but they are still moving. If the pieces get close enough together, will they reform a functional hand and come after you?
