"But I'll be arrested for murder, the minute I show myself," Marc protested. "And who'd believe any of this, anyway? What about that?" "Those," the doctor said wearily, spreading his long hands before him, "are your problems. I'm sure you'll find a solution to them." Toffee rose gracefully from her chair and swung easily toward the desk. "You make it all sound so easy, doctor," she said acidly. And so startling was her movement, so distracting her lovely body in motion, that neither Marc nor the doctor noticed that, in turning, she had scooped the gun from the corner of the desk, where the doctor had dropped it. But now that they did notice, another fact was also blaringly apparent. She was pointing the gun in the wrong direction. Grasped by the muzzle, it was aimed directly at her own smooth midriff. "Hands up!" she announced dramatically. "Turn it around!" Marc yelled. "You're sticking yourself up!" "If you press that trigger," the doctor said calmly, "I'll press this button." His hand was already moving across the desk. Marc swung quickly out of his chair, but overlooked the fact that one foot was still twisted nervously around a metallic leg. It was a disastrous oversight. The tardy foot, working in stiff opposition to his urgent forward movement, he sprawled awkwardly in mid-air, then came down, head-first, on the gleaming floor. Coming to haphazard rest, he rolled over, grinned foolishly, and closed his eyes in involuntary slumber. He was out like a cat at night. The minute Marc's eyes closed, the gun skittered chatteringly across the floor. Toffee couldn't have held it any longer, if she'd wanted to. She'd vanished into thin air. Dr. Herrigg stared bewilderedly at an area which, to his scientific mind, had no right to be vacant. A moment ago it had been occupied by a highly disconcerting young lady with red hair. Now, it was as empty as a rejected lover's heart. He passed a hand over his eyes, then looked again. It was still empty. * * * * * Something cool and damp struck Marc across the face, and he opened his eyes to find the doctor peering anxiously down at him, a cloth in his hand. "Where is the girl?" he demanded. Marc sat up and stared at him blankly, wondering the same thing. Toffee should be materialized, now that he was conscious again. "I don't know. You haven't done anything to her?" "Of course not. She was right here when you fell. She simply vanished." "She must have sneaked out during the confusion," Marc said, thinking that what the doctor didn't know wouldn't hurt either of them. It was his own opinion that Toffee had materialized elsewhere and gone for help. "But that's impossible! This place is locked electrically." "In her way," Marc replied smilingly, "Toffee is rather scientific herself." "Well, my men will catch her before she goes very far," the doctor said a bit more calmly. "She won't be able to get away." "Your men?" "Oh, I have quite a staff here."
