"Yes—such is my determination," answered Tom.

Old Death opened the clock, and touched some secret spring inside. This was immediately followed by the noise of wheels, accompanied by a peculiar sound as of a windlass turning rapidly; and in a few moments Rainford perceived that the entire clock itself was moving slowly along the wall, revealing by degrees an aperture in the floor.

In about a minute the working of the machinery ceased—the clock-case was once more stationary—and in the place where it first stood was an opening cut in the boards, large enough to admit the passage of even a moderately stout man.

"Shall I go first?" asked Old Death, with a sardonic smile, which seemed to indicate his opinion that Rainford would not venture to follow him.

But if such were really his idea, he was disappointed; for the highwayman said in the coolest manner possible, "By all means, old chap. And make haste about it—for the night is passing away, and as yet I have seen scarcely anything."

Old Death made no answer, but began to descend an iron ladder, to which the aperture led; and as he gradually went down the steps, he held up the candle in one hand, and with the other supported himself by means of a rope hung for the purpose.

Tom Rain unhesitatingly followed him; and when he reached the bottom of the ladder, he found himself in a long, narrow, vaulted passage, apparently stretching far underground, but to the end of which it was impossible for the eye to penetrate, so feeble and flickering was the light afforded by the candle.

"Wait an instant while I close the entrance," said Old Death: "it is a precaution I never neglect."

"Quite right," observed Tom coolly; and while he affected to be leisurely whistling a tune, he was in reality keeping a most careful watch upon his companion's movements.

Old Death pulled a thick wire which hung down from the top of the vault, and the mechanism of the clock was again set in motion, until the clock-case itself had resumed its usual station over the entrance to the vaulted subterranean.
