"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.
