"But you—"' protested Gladys.
There came the sound of rapid footsteps in the next room. Hal picked Gladys up in his arms, carried her to the window, and dropped her to the ground as he said in a low voice:
"To hesitate means failure. Do as I say and quickly."
He returned to McKenzie's side. When he reached there McKenzie extinguished his light.
"Well, we've got the list," he said quietly.
"We have," Hal agreed, "but our lives probably will pay the forfeit. We must stay here until we are discovered. To follow Gladys would mean her capture."
"We won't have to wait long," said McKenzie grimly. "Here they come."
It was true.
Footsteps came toward them. Suddenly the room burst into light as someone pressed an electric, light button. General Rentzel strode into the room.
His eyes fell upon Hal and McKenzie immediately. He said nothing, but gazed about. Then he saw the shattered safe. He dashed forward with a cry and examined the interior, carefully. Then his face turned white as he faced Hal.
