With a yell, Snackley flung the man to one side. “Down into the cave!” he roared. “Quick!” Confusion prevailed. In the resulting uproar the match went out and the room was plunged into darkness. Frank resolved on a daring move. He was standing directly beside one of the smugglers, and as soon as the light went out he sprang at the fellow, dashing the revolver from his grasp. It clattered on the floor. “Help!” roared the fellow, as they grappled together. Fenton Hardy had also been watching for his chance, and he sprang through the darkness at Snackley. He collided heavily with the chief of the smugglers and they rolled on the floor in a desperate struggle. It was impossible to distinguish friend from enemy in the darkness. Joe plunged into the midst of the surging figures and his fist smashed against the face of one of the smugglers, who gave a howl of pain. Then, outside the house, another uproar burst forth. Some one was banging on the front door. Men could be heard shouting to one another. Snackley made a desperate effort and managed to get to his feet. He struck out with both fists and managed to break free from the detective. He whirled to one side, stumbled out into the kitchen, and then reached the back door. He flung the door open. Almost instantly a dark figure appeared in the doorway. It was the figure of a man in the uniform of a state trooper with drawn revolver and Snackley shouted the warning to the smugglers in the other room. “The police!” he roared. “Every man for himself! Make your getaway!” The trooper shot through the doorway at him, but Snackley dodged to one side. There was a rush of footsteps from the other room as the rest of the smugglers raced out into the kitchen. The officers tried to hold them back, but they were too many for him and he was hurled against the wall. Utter confusion prevailed. The place was in absolute darkness and out in the yard shots, shouts and hoarse imprecations mingled in an indescribable uproar. One of the smugglers managed to reach the shed. He flung open the trapdoor and descended the steps. Some of his companions followed, and in the darkness and excitement their escape was unnoticed. Half a dozen police officers were in the yard. They had been attracted to the house by the sound of the shots when the Hardys were pursued by the smugglers, and they had planned to surround the place. They would have succeeded in capturing the entire gang had it not been for the man on guard outside. Back in the living room of the house Frank was still struggling with his antagonist. The man was strong and heavy, a rough-and-tumble fighter, and the boy soon found that he had his hands full. They struggled desperately in the darkness, the smuggler frantic with the fear of capture, Frank grimly resolved that the man should not get away.
