"You haven"t any right to lock us in here."
"Then we take the right," answered Tom grimly.
"Let us smash the door down," came in a low tone from inside the room.
"If you try it we"ll surely fire," said d.i.c.k, and c.o.c.ked his pistol so the men might hear the click. Tom did the same with the shotgun.
"See here, you let us out and we"ll make it all right with you,"
remarked Sh.e.l.ley, after another pause. "We are not the bad fellows you take us to be. We were only going to play a joke, that"s all."
"I suppose you think Sid Merrick"s doings are a joke, too," said Sam, before he had time to think twice.
"Ha! what do you know of Merrick?" e.j.a.c.u.l.a.t.ed Cuffer. "They must have been listening to our talk," he added, in a low tone to his companion.
"Yes, and if so, we are in a bad box," answered Sh.e.l.ley. "I"d give a good deal to be out of here just now."
"Talk to them, while I take a look around," continued Cuffer, struck by a sudden idea.
Sh.e.l.ley did as told, pleading with the three Rovers to let him go and offering to pay fifty dollars for his liberty. He talked in a loud tone, to cover up what noise his companion might make. The boys listened, but refused to open the door until some sort of help should arrive, or until morning came.
"Sam, you go outside and see if Jack and the Ditwolds are anywhere around," said d.i.c.k, and the youngest Rover departed immediately.
Presently Tom and d.i.c.k heard Cuffer give a cry of pain.
"You"ve stepped on my sore toe!" howled the man. "Phew! how it hurts!"
The two men talked about the hurt toe for several minutes. Then their voices suddenly ceased. Tom and d.i.c.k strained their ears, but could hear absolutely nothing.
"They must be up to some trick," whispered the eldest Rover. "Hi, you, what are you doing?" he called out.
There was no answer and the silence was just as ominous as before. The light in the inner room had gone out.
"What are you doing?" repeated d.i.c.k, and ran close to the door to listen. Nothing but absolute silence followed.
What to do next the two boys did not know. They waited for fully five minutes--then five more. Presently they heard Sam coming back.
"I yelled for Jack and the others, but I got no answer," said he. "What are the men doing?"
"We don"t know," answered Tom. "We are afraid they are up to some trick."
"A trick?" repeated Sam. Then he gave a gasp. "The room--isn"t there a back door, leading out to the shed?"
"I don"t know," answered d.i.c.k.
"I"ll run and see."
Sam was gone less than two minutes when they heard a cry, and then he pounded on the door they had so carefully guarded.
"There is a back door and it is wide open. The men have gone!" was his dismaying announcement.
CHAPTER VI
THE STORY OF A TREASURE
It was a disheartening discovery, but the three Rover boys did not stop to think it over. Throwing open the bolted door, Tom and d.i.c.k joined Sam, and in the darkness made their way to the rear of the room in which they had held Cuffer and Sh.e.l.ley prisoners. In a minute more they were outside, under the trees at the rear of the old mill.
"Which way did they go?"
Tom asked the question, but n.o.body could answer it. The moon had now gone under some clouds and it was so dark they could scarcely see ten feet in any direction.
"Perhaps they took to the river again," suggested Sam.
"It is not likely," answered his big brother. "But we can take a look."
They ran around to where the men had landed. Their boat was still in its place, tied to a tree.
"Listen!" cried Sam. "Somebody is shouting, and there is a light."
"It is Jack Ness," said Tom.
The boys set up an answering shout, and soon a boat came up to the sh.o.r.e. It contained the hired man and the two Ditwolds. They had a lantern with them and also an old-fashioned single-barrel shotgun.
The situation was quickly explained, and then the party of six began a systematic search of the woods and the various roads in the vicinity of Henderson"s mill. This search lasted until morning, but nothing came of it.
"We may as well give up," said d.i.c.k, at last. "They have gotten away and that is all there is to it."
The boys were completely tired out when they got home. Their uncle and aunt were much worried over their prolonged absence and overjoyed to see them return unharmed.
"I was so afraid one of you might get shot or something," said Mrs.
Rover. "Some of those chickens thieves are desperate characters."
"Those men were more than chicken thieves," answered d.i.c.k. And he told his uncle and aunt of the conversation overheard at the old mill.
"It is a great pity that they got away," said Randolph Rover.
"What do you imagine they are after. Uncle Randolph?" questioned Sam.
"I do not know, excepting it may be some mining stocks or a deed to some property. Perhaps your father will be able to explain it when he gets back."
The authorities were notified, but they failed to apprehend the men. It was learned that the boat they had used had been stolen from a point near Oak Run, and the craft was returned to its owner. That they had used the old mill for a stopping place was evidenced by the remains of numerous meals found there. The boys made a careful search of the premises, but brought nothing to light which was of use to them.
"I wish father was home--or we knew how to reach him by telephone, or with a telegram," remarked d.i.c.k.
"Well, we can"t reach him, so we"ll have to be patient until he returns," answered Sam. "By the way, I wonder if his going away had anything to do with what those men were up to?"
