"Who is between us?" he ejaculated.
"The devil!" cried the sexton, leaping from the coffin-lid with an agility that did him honor. "Is aught between us?"
"I will discharge my gun. Its flash will light us."
"Do so," hastily rejoined Peter. "But not in this direction."
"Get behind me," cried Luke. And he pulled the trigger.
A blaze of vivid light illumined the darkness. Still nothing was visible, save the warrior figure, which was seen for a moment, and then vanished like a ghost. The buck-shot rattled against the further end of the vault.
"Let us go hence," ejaculated the sexton, who had rushed to the door, and thrown it wide open. "Mole! Mole!" cried he, and the dog sprang after him.
"I could have sworn I felt something," said Luke; "whence issued that groan?"
"Ask not whence," replied Peter. "Reach me my mattock, and spade, and the lantern; they are behind you. And stay, it were better to bring away the bottle."
"Take them, and leave me here."
