With the eyes of a madman he stared--and listened.

His arms relaxed from about Joanne, and she slipped crumpled and lifeless to the floor.

He stared--and that steady _beat-beat-beat_--a hundred times louder than the ticking of a watch--pounded in his brain.

Was he mad?
He staggered to the choked mouth of the tunnel, and then there fell shout upon shout, and shriek upon shriek from his lips, and twice, like a madman now, he ran back to Joanne and caught her up in his arms, calling and sobbing her name, and then shouting--and calling her name again.

She moved; her eyes opened, and like one gazing upon the spirit of the dead she looked into the face of John Aldous, a madman's face in the lantern-glow.
"John--John----" She put up her hands, and with a cry he ran with her in his arms to the choked tunnel.
"Listen! Listen!" he cried wildly.
