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.

"The list," he said in a hoarse voice, "where is it?"

Hal smiled.

"Where you will never get it, I hope," he replied quietly.

General Rentzel strode forward with a shout.

"They are spies! Seize them, men!" he cried.

Hal's right arm shot out and the chief of the German secret service
sprawled on the floor.

"To the stairs!" Hal cried to McKenzie.

The Canadian needed no urging. Two German soldiers fell to the floor
under his quick blows and then McKenzie joined Hal on the steps which
fled upward from the rear of the room.

Hall produced a revolver. McKenzie did likewise.

"The first man who moves dies!" cried Hal, as he moved his revolver
from side to side.
