Nathan rose. It was as if an electric charge had been thrust between the other men.

"I'll find the killer," said Nathan evenly. He looked down at the form on the cavern floor. "I'll find him if it takes the rest of my life. Why did he warn me of Firebird? Was it only because of the Jewels or do you think she could have done this?"

"He hated Firebird because of an old quarrel. She might have done it, but I don't know. I was with Thymar in Aquatown when he received a message saying information concerning the Blue Jewel could be found here. He went alone and we were to meet a day later to leave for Mars. He didn't show up so I came here and found him like this."

Nathan nodded. The policeman, Cleeg, had told him that much after Tabor had sent word. But that was no help. It only served to fix Nathan's hatred more intensely upon the cursed Seven Jewels of Chamar.

"Was my father carrying any of the Jewels when he came here?"

"He had the Pink one. I tried to warn him, but he said he could take care of it."

"And now it's gone, of course."

Tabor nodded. "The whole thing was a trap by someone who knew he had it."

"Who knew of it?"
