"Get back in the corner and crouch down, McKenzie," said Hal, and did
the same thing himself.

At that moment there was a crash in the adjoining room. Hal's revolver
leaped out, as did McKenzie's, and both dashed into the room. McKenzie
flashed the light across the floor, and there, just getting to her
feet, was Gladys.

"Quick! You must fly!" she cried. "General Rentzel is on his way and
will be here at any moment."

The fuse in the other room was burning fast, as Hal knew. The lad
determined, in that instant, that he would not leave the house without
getting the list for which he had come.

He pulled Gladys back into the room where the fuse was fast burning to
the safe. McKenzie followed, and the three crouched down.

A moment and there was a muffled explosion, followed by a flash of
fire. Smoke filled the room. With a cry to the others to stay where
they were, Hal dashed to the safe. It was as he hoped. The door had
been blown clear.

Quickly Hal explored the contents of the safe. Then he gave a cry of
delight. His hand encountered what he felt sure was the book he
sought. He ran across the room with it to where McKenzie held the
flashlight and by its glow examined his prize.

It was the list he sought.
