“We’ll go back this way, sir,” said Ben; and he went on first with the lantern, till he came to one of the flights of stone steps leading up to the ground level.

“Let’s go on here, Ben,” said Roy; and, upon their reaching the corridor above, the boy looked back along it towards where the stairs went up into the corner tower, beneath which they had been so busy.

“Wonder whether Master Pawson heard us, Ben.”

“Can’t say, sir. I should fancy not, or he’d have been on the stir to know what was the matter.”

“Mightn’t have cared to stir in the dark, Ben. I say, I should like to know. Look here, he went off early to bed, because he said he was unwell. I’ll go and ask how he is. That’s a good excuse for seeing.”

“Well, so it is, sir,” said Ben, rubbing his ear; “and if he did hear anything, he’d be pretty sure to speak.”

“Of course. Then I will go. Come and light me.” Roy hurried along back with Ben following and casting the boy’s shadow before him, till they reached the arched door-way, where they went up the few stone steps in the spiral staircase, reached the oaken door leading into the apartments, felt for the latch, raised it, and gave it a loud click; but the door did not yield to the boy’s pressure, and he tried it again, and then gave it a shake. “Why, he has locked himself in, Ben!”

“Has he, sir? Didn’t want to be ’sturbed, maybe.”

“Perhaps he was frightened by the noise we made, and then fastened himself in,” said Roy, with a laugh.

Ben chuckled at the idea.
