"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."

"How do you keep them? Surely they don't approve of what you're doing?"

"They were brought here just as you were. They think they're on a very secret mission for the government, and remain as voluntary prisoners."

Toffee's face bore only the marks of outrage.

"Get those clammy hands off me!" she shrieked, "or I'll scratch that nasty face of yours right out of existence!"
