“Gone,” repeated Jack.
“Yes; and I would like to know where.”
“Let’s go in and see.”
Their hands rested upon their revolvers as they advanced into the room and looked about. From one end to the other they searched, when as they were about to give up, Frank discovered a door behind some old barrels in the far corner.
“Here is where they went,” he whispered.
He tried the door, and it gave way before him, though not until he had used considerable force. A pair of stairs, going down, confronted them.
“Shall we go down or not?” asked Frank, turning to Jack.
“Suit yourself,” was the reply. “I’m with you either way.”
Without another word Frank turned about and began to descend the stairs, taking care to make no noise. Jack followed him.
At the bottom, where it was pitch dark, they brought up against a second door, and making sure that his revolvers were ready for instant use, Frank pushed it gently.
