"No one in sight," he informed his companions, and softly the four stepped outside, closing the door gently behind them.

Silently four shadows flitted along the corridor, out across the bridge and to the wall beyond. They encountered no one.

"Your Uncle Billy is a jewel," declared the young Frenchman, in a whisper.

"He is for a fact," whispered back the lieutenant.

Chester crept silently through the gate and peered in all directions.
Then he crept back to his companions.

"All safe!" he whispered.

"Now to get to the place where Uncle Billy said friends would be waiting," said Hal.

"I guess we had better make it at a run," spoke up the Frenchman.

"Yes," said the lieutenant; "some one might happen along and we would have to make a fight for it."

Passing through the entrance to the old castle, the four broke into a run, and turning to the right in accordance with their instructions, increased their speed.
