The secret of the caves

It was a Saturday afternoon in June, one of those warm, drowsy days when even the leaves of the trees seem too indolent to stir. There was scarcely a ripple on the surface of th...

As the Hardy boys sped toward the woman, who appeared above the surface again in a moment and began to struggle wildly, they saw that confusion prevailed on board the yacht.

Frank Hardy lost no time on the run back to Bayport. Instead of proceeding directly to the boathouse, he docked the _Sleuth_ at one of the city wharves. There the lads were fort...

It was quite evident that Miss Todd was in no condition to go to any of the city hotels. She needed rest and quiet more than anything else, and when she had been revived a few m...

Vacation time came, as it always does, although the days dragged, and when the last examination was written and the Hardy boys and their chums faced the long summer holidays, th...

The Hardy boys, Chet Morton, and Biff Hooper were celebrating their departure by treating Callie Shaw and Iola Morton--and incidentally, themselves--to ice-cream at the Bon Ton...

The motorcycle had been stolen. There was no doubt of that. That it had been stolen within that past five minutes, he knew. When the boys were coming out of the water he thought...

The Hardy boys and their chums spent the night at a hotel in a small village. They were up bright and early next morning, eager to reach the end of their journey. Had it not bee...

"If it's rum-runners, they'd be bringin' their cargoes out to the road, wouldn't they? Not much sense in 'em hidin' the liquor in the caves and leavin' it there, is there?"

They peered into the gray oblivion of the storm, but the rain was teeming down in such heavy torrents and the gloom was so intense that it was impossible to see more than twenty...

With the goal in sight, the Hardy boys and their chums hastened down the treacherous path, along the steep side of the ravine. The path was slippery and little rivulets of water...

"I guess I was right, then," declared Joe. "There really _was_ somebody. I thought for a minute it might be one of you playing a trick on the rest of us."

With only their flashlights to illuminate the huge cave, they found it difficult to conduct the search with any degree of satisfaction. They blundered here and there, not at all...

When the three boys reached the cave where they had last seen Frank Hardy they piled the driftwood in a heap close by one of the pits in the floor.

Having concluded this verse, the strange old man elevated one arm above his head and danced a couple of steps of a sailor's hornpipe. In the middle of this he caught sight of th...

"This is very strange. I had no idea there was any one else around this part of the coast. You can see for yourself that it is hard to get here, and if there were any one else a...

"It certainly looks strange. But how _could_ this queer old chap be Todham Todd? How would the college professor get away down among these caves, and what would be his idea in p...

It was a small package containing several tins of meat, of the same variety the Hardy boys and their chums had brought with them on their expedition to the caves.

Their friend, the fisherman, was greatly interested in the Hardy boys' adventure with Carl Schaum and wanted to know all the details of the affair. Frank and Joe told him why th...

Evidently, it took him some time to become accustomed to the dim light of the cave, for he was peering intently at the boys, but with no sign of recognition on his face.

To Frank Hardy's unbounded astonishment, the explosion was followed by a white cloud that rose from the barrel of the shotgun. It was not smoke, and although Captain Royal had a...

"There's still a chance," he shouted to the others. "He may be alive yet. If we hurry we may be able to get him out of the water before he drowns. The tide's coming in, so he ma...

"I don't think he's been badly hurt." Chet began feeling the unconscious man's ribs. "There are no bones broken, at any rate. He hit his head against a rock, I guess."

Next morning, refreshed by their sleep, Frank, Joe and Chet were downstairs early, but not earlier than Fenton Hardy, who was already busy in his office clearing up some work be...

Todham Todd hovered between life and death for almost two weeks. For days he lay unconscious, knowing nothing of the efforts that were being made to save him. He had the best of...
