"Stop!" she snapped.

Using the Voice again! He swung his attention back to her face.

"I hold at your neck the gom jabbar," she said. "The gom jabbar, the high-handed enemy. It's a needle with a drop of poison on its tip. Ah-ah! Don't pull away or you'll feel that poison."

Paul tried to swallow in a dry throat. He could not take his attention from the seamed old face, the glistening eyes, the pale gums around silvery metal teeth that flashed as she spoke.

"A duke's son must know about poisons," she said. "It's the way of our times, eh? Musky, to be poisoned in your drink. Aumas, to be poisoned in your food. The quick ones and the slow ones and the ones in between. Here's a new one for you: the gom jabbar. It kills only animals."

Pride overcame Paul's fear. "You dare suggest a duke's son is an animal?" he demanded.
