CHAPTER XVII
The Chamber in the Cliff
Frank switched on the flashlight.
The beam illuminated the depths of the dark passage. Far ahead of the brothers they glimpsed a grey shape just above the surface of the glistening water.
For a moment they were startled, then they recognized that the grey shape was nothing more than the rowboat that had passed by them in the darkness outside the cove. It had been drawn up close to a natural wharf hewn out of the solid rock. It swayed to and fro with the motion of the water.
The boys made their way forward along the ledge, which was wide enough for one person to walk on, until at last the ledge widened out and proved to be a path leading to the wharf.
There was not a sound in the passage but the drip-drip of water from the gloomy walls.
The Hardy boys stole quietly forward along the wharf, passed the boat, and then looked about them.
