Mark Carter stepped out of the shadows. His tanned face looked as if it had been carved from the rock of ages. His eyes were pools of sudden death.

He spoke:

"Elaine's gone, Vance. Through the mirror. We want her back."

Just that. Nothing more. But suddenly Vance was shaking.

"What are you talking about? I don't know what you mean."

Professor Duchard said:

"You are lying. I have examined the mirror. I tested with black light. It showed the picture of the first Elaine Duchard."

"You're mad," said Vance. "You don't make sense."

"I fear I make too much sense, Adrian Vance. I wish I could disbelieve my own mind. But I cannot. I know that you have found a way to pass the barrier between space and time. I know that you have projected Elaine's mind into the past, leaving her body behind in a state of suspended animation."
