“Yes, sir,” he said at last, with a sigh.

“Then come with me.”

“Come with you, sir?”

Dexter looked at his stained and muddy clothes.

“Yes,” said the doctor; “come with me.”

Sir James shrugged his shoulders slightly, and gave the doctor a meaning look.

“Good-bye, Grayson,” he said, and he shook hands.

“As for you, sir,” he added sternly, as he turned to Dexter, “you and your companion have had a very narrow escape. If it had not been for your good friend here, matters would have gone ill with you—worse perhaps than you think.”

Dexter hung his head, and at a sign from the doctor went to his side, and they walked out of the station with Dan’l and Peter behind.

The doctor stopped.
