Norman shook hands automatically. Although he refused to look at the body his mind persisted in picturing it. He said, "Doctor, do you realize there's a killer loose among us?"

"What do you take me for? A simpleton?" snorted the doctor.

"But Doctor," put in Jennifer; "if he was working on the terror, he must have discovered something. Else, why should they have killed him?"

"I'd thought of that," interrupted Norman. "Do you suppose we're headed for the same fate as those other ships? We're carrying radium."

"Nonsense," grunted the doctor. "That agent might have been on the trail of smugglers, anything. Oh, here comes the Captain."

The Captain, a brusque little man who appeared to be in his fifties, glanced briefly at the body, said: "Who found it?"

Several passengers pointed out Norman.

"I?" said Norman in haste. "I didn't find it. That—that...." He flung his eyes over the crowd in search of the fat woman, but she had been carried to her stateroom. He took a breath, began again. "Miss Scott and I were going to lunch. We were right behind an Earth woman. She saw the body first."

"You didn't see anyone enter or leave this passage?"

He emphatically shook his head.
