"He cut the ropes!" cried Josiah Crabtree. "But how he got hold of his knife to do it, I can't guess."
Dick had to smile to himself. Evidently the rascals thought his father had liberated himself and turned the tables on them.
"Hi, Rover! Are you out there?" called Jesse Pelter. "If you are you had better unlock that door."
To this call Dick did not answer.
"He must have run away!" exclaimed Japson. "Break the door down! We must catch him!"
"That's the talk!" added Josiah Crabtree, in great excitement.
"Touch the door at your peril!" cried Dick, sharply. "I am armed and I will stand no nonsense!"
"Who is that?" asked Japson.
"That wasn't Rover's voice," added his partner.
"I think I know who that is," answered Josiah Crabtree, and his voice commenced to tremble. "Dick Rover, is that you?" he called, faintly.
"Yes, Don't you dare to touch that door, Crabtree," replied Dick.
"Is it Dick Rover?" questioned Pelter.
