saw passing civilians, with now and then an officer or trooper or so,
but Berlin seemed to be sleeping securely in the knowledge that the
enemy was far from its door.

Hal gazed at his watch by the glare of a street light. It was almost 4
o'clock.

"Two hours to daylight," he muttered. "We shall have to hurry."

Fifteen minutes later Stubbs slowed down.

"My automobile is in a small garage around the next corner," he said,
and added significantly, "if nothing has happened to it."

"Let's get it then," said Hal. "We don't want to stand here."

Stubbs moved on again and Hal and McKenzie followed him closely.

There was no sign of a living person near the little garage. Stubbs
approached and attempted to throw back the closed door. It would not
budge.

"Let me try, Stubbs," said Hal, pushing forward.

He took from his pocket a short but well tempered piece of steel. He
found that the door was held by a padlock. He inserted the piece of
steel in the top, and, putting forth all his strength, broke the lock.

There was a sharp report as the lock fell to pieces.
