"You I shall kill," he grinned evilly. "But not now. First you must taste the horror of sinking into the long sleep. You have no more drug, nor can you obtain any. Those pitiful storage batteries will be exhausted by the time you have aroused the child. So you must sleep unless you have the courage to kill yourself. Doctor, I deeply regret that this has occurred, but you see that I must let you and June sleep too. When I have need of you I will recall you. That is all. Farewell. May God pity you, Baron. I will not."
He sprang through the door and, the tails of his black coat flapping like the wings of a gigantic bat, vanished down the stairs.
Manthis slammed the door and locked it, then leaned weakly against the panels and wiped his round face. His hands shook pitifully.
"This then is the end," he whispered hoarsely.
"Is there none of the drug left?" Jack shook him out of his lethargy.
"Enough for a half portion for all of us," sighed the doctor. "But what use of that? Better we poisoned ourselves now and escaped that demon."
"Nonsense. A half portion means twelve hours of life. In that time I can rig up the big transmitter. Perhaps there is still time to revive New York. Solinski won't know we have a generator until we turn on the power. Quick. Poor June must be nearly frightened to death at our shouting."
But they found the girl sitting tense and jubilant at the controls.
"Father! Jack!" she cried as the door opened. "It's working. I saw her move. That means we may be able to revive the world!" Her face was streaked with tears.
