"And he wants to go to the station, which I wish he would do promptly,"
observed Roland, in some suspense.

"But she wants him to drive up to the house. See, she points that way,"
said Nat.

The woman climbed into the carriage, and the driver turned toward the
castle. The boys prepared to make their escape.

"They'll go out the back way," ventured Nat. "Now's our time!"

At that instant a shrill scream rent the air. It was the same, only much
louder, that had startled the party before.

"The ghost!" gasped Roger, jumping into the car.

The others followed. The carriage had made a quick turn and was now almost
upon them.

Ned put on full speed, and was soon out on the open road.

"What's the answer?" asked Tom, who could not make out what all the fuss
was about.

"Did you see Abe's face?" asked Nat as they once more felt that it was
safe to exchange remarks.

"Almost went white," replied Ned. "None is so frightened at ghosts as a
darky."
