Hoddan was puzzled for a moment. Then he realized that Derec's information about the fleet came from the spearmen he'd brought back, loaded down with cash. Derec hadn't noticed the absence of the flashing lights at sunset—or hadn't realized that they meant the fleet was gone away.
"Hm-m-m," said Hoddan. "Why don't you think I've already done it?"
"Because they'd have killed you," said Derec. "Don Loris pointed that out. He doesn't believe you know how to make deathrays. He says it's not a secret anybody would be willing for anybody else to know. But ... you know the truth, Bron! You killed that poor man back on Walden. You've got to sacrifice yourself for humanity! You'll be treated kindly!"
Hoddan shook his head. It seemed somehow very startling for Derec to be harping on that same idea, after so many things had happened to Hoddan. But he didn't think Derec would actually expect him to yield to persuasion. There must be something else. Derec might even have nerved himself up to something quite desperate.
"What did you really come here for, Derec?"
"To beg you to—"
Then, in one instant, Derec made an hysterical gesture and Hoddan's stun-pistol hummed. A small object left Derec's hand as his muscles convulsed from the stun-pistol bolt. It did not fly quite true. It fell a foot or so to one side of the boatport instead of inside.
It exploded luridly as Derec crumpled from the pistol bolt. There was thick, strangling smoke. Hoddan disappeared. When the thickest smoke drifted away there was nothing to be seen but Derec, lying on the ground, and thinner smoke drifting out of the still-open boatport.
Nearly half an hour later, figures came very cautiously toward the spaceboat. Thal was their leader. His expression was mournful and depressed. Other brawny retainers came uncertainly behind him. At a nod from Thal, two of them picked up Derec and carted him off toward the castle.
