"Fine. We'll go now."
They left the cave, unmindful of the appeals of the auto thief, and made their way down a passage that led into the outer cavern where the stolen cars were stored. The light showed them a large opening that they had not seen when they were in the place on the first occasion.
"I guess this is the way they drive the cars out," remarked Frank. "We'll go out the way we came in. We won't be so likely to meet the others."
The boys hastened down the far passage. They hurried past their roadster, on through the tunnel. At last they saw a gleam of light ahead, shining faintly in the distance.
CHAPTER XXI
At the Farmhouse
In a few moments, the Hardy boys had emerged from the passage and stood in a heavy clump of bushes that obscured the entrance to the tunnel in the bluff. Brushing aside the trees, they stepped out onto the beach.
The light they had seen was from a ship, steaming into Bayport Harbor, and in the distance they could see a dim yellow haze—the lights of the city.
Above them towered the rocky bluff. Farther down the beach they saw the break in the cliffs where the gully ran back toward the Shore Road.
