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. Great clouds of smoke were...

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 fortunate enough to find a ta...

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 minutes later, Mrs. Hard...

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, the boys had more excitin...

“I wish I were a boy,” sighed Callie Shaw. Iola Morton looked up from her ice-cream soda. “Me, too.” “It’s tough luck that you’re not,” said Joe Hardy. “We’d like to have you along on the trip with us...

Frank Hardy wasted no time. 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 th...

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 been for the delay consequ...

Chet Morton laughed. “We heard there were some queer things happening around here, but that doesn’t frighten us.” “There’s nothing to laugh at, young man,” returned the fisherman tartly. “I’ve lived h...

The boys gazed at one another in surprise. “Where on earth did Joe disappear to?” exclaimed Biff Hooper. They peered into the gray oblivion of the storm, but the rain was teeming down in such heavy to...

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 ran at their feet. Che...

“Who is that?” demanded Joe Hardy, scrambling to his feet. There was no answer. He heard the sound of running footsteps gradually growing fainter. “Hey, there!” he shouted, now thoroughly aroused. “Fe...

The other boys searched for nearly an hour, but Frank Hardy seemed to have disappeared literally into the bowels of the earth. With only their flashlights to illuminate the huge cave, they found it di...

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. They were surprised at the number of holes and crevi...

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 the boys, and came to an ...

“Someone came into our cave last night and stole most of our supplies,” said Frank. “A man!” “We didn’t see him, but it could scarcely have been an animal of any kind, for he carried off a whole box o...

The Hardy boys looked at one another solemnly in the glow of the campfire. “Do you think Captain Royal and Todham Todd are one and the same man?” asked Joe. “What do you think of it yourself?” “It cer...

Carl Schaum did not awaken. His slumber was too deep. He was quite senseless from the effects of the liquor he had drunk. “This is luck!” exclaimed Frank. “I wonder how he got here!” “I suppose he’s h...

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 they had captured Schaum,...

So quietly had the man approached the cave mouth that the Hardy boys were taken completely by surprise. They wheeled about. There, in the entrance, stood Captain Royal. Evidently, it took him some tim...

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 aimed the gun directly a...

The boys looked at one another in awe. Their ears still rang with Captain Royal’s last dreadful cry as he went hurtling over the cliff toward the watery depths. “He’s gone!” gasped Chet. “I knew somet...

Captain Royal was unconscious, but he was still breathing. There was a bad cut on his head and it had bled profusely. “We’d better get him to a doctor right away!” said Joe. “I don’t think he’s been b...

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 before breakfast. He welc...

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 care, and the doctor g...
