The captain was silent for a long moment. Then he said, "But we've no Miss Ramsey on the passenger list. And I certainly didn't invite her to drink a toast with me in my cabin. Are you sure of your facts, Lieutenant?" Corriston's jaw fell open. He stared at the captain in stunned disbelief. "Of course I'm sure. Why should I lie to you?" "How should I know? It's unfair to ask me that. If Ramsey's daughter was on this ship, you can rest assured I'd have known about it. After all, Lieutenant—" "But she was on board and you didn't know. Isn't that obvious? Look, she was traveling incognito. The trip to the Station takes only five hours. Perhaps in so short a trip—" "No 'perhaps' about it. I'd have known." "But she is on board, I tell you. I talked to her. I talked to Clakey. Don't make me go over the whole thing again. We've got to find her. Ramsey's enemies would stop at nothing. I'm afraid to think of what they might do to his daughter!" "Nothing will happen to his daughter. She's on Earth right this minute in her father's house, as safe as any girl that wealthy can ever be. Lieutenant, listen to me. I've got a great deal of respect for that uniform you're wearing. Don't make me lose it. When you come to me with a story like that—" "All right. You don't believe me. Will you check the passenger list, just to be sure?" "I'll do more than that, Lieutenant. I'll assemble all of the passengers and check them off personally. I'll give you an opportunity to look them over while I'm doing it. Later you can ask them as many questions as you wish. There'll be a murderer among them, but that shouldn't disturb you too much. You've already met. Perhaps you can identify him for us. Ask each of the men who made a non-existent Miss Ramsey disappear and the one who turns pale will be our man." Suddenly the captain reddened. "I'm sorry, Lieutenant, I didn't mean to be sarcastic. But a murder on my ship naturally upsets me. I'll be completely frank with you. There's a very remote possibility that Miss Ramsey actually is on board without my knowledge. She hasn't had much publicity. I believe I've only seen one photograph of her, one taken several years ago. But you've got to remember that a captain is usually the first to get wind of such things. It comes to him by a kind of grapevine. She's a golden girl—actually the goldenest golden girl
