“I can’t help suspecting it.”

“I don’t, even though their hanging about Doctor Spellman’s home has a bad look. Those kidnappings are done in the cities,—not in the open country like this; and then think for a moment of the conditions. For two tousled bums to steal a little girl, and compel her father to pay a ransom for her,—here in the Maine woods, within a few miles of Boothbay Harbor,—why the thing is preposterous.”

“Has it occurred to you that they may be connected with others? They may be agents of the Mafia or Camorra or some regularly organized gang of kidnappers.”

This was new to Alvin, and disturbed him painfully. What was improbable about it? The persistency of Biggs and Hutt in prowling about the lake suggested a strong motive,—such as that of earning a big reward through the commission of some such crime as indicated.

“I tell you, Chest, none of us has gone the right way about this business. Suppose Chief Spofford or some other officer succeeds in arresting the two tramps, what good will it do? They are not such fools as to walk into a town with a little girl in their charge. They would be called to account on sight without any request from her friends. As we agreed, we must pin our faith on the bloodhound, and we may not find him for days, when the trail will be so cold that even he cannot follow it.”

The two felt that for the present they were at the end of their rope. They had done all they could to set the wheels in motion for the arrest of the tramps who were under suspicion, and the dread was strong with them that if such arrest could be brought about it would affect nothing. Any plan for the kidnapping of the little girl would be so cunningly laid by master minds that their agents would never walk into a trap, no matter how skilfully set.

“We must find Burton and his dog,” was the last remark of Alvin. His companion murmured assent and then the two sank into the sleep of weariness and sound health, because of which they did not awake until the young man who had received them the night before hammered on the door and shouted that breakfast would be ready in ten minutes.

With self-reproaches they bounded out of bed, hurried through their preparations, and went down stairs two steps at a time. The meal was on the table, and for the moment they were the only guests, with the young man referred to acting as waiter.

The boys had hardly seated themselves when through the open door entered a third guest, accompanied by a black, sturdy, long-eared dog, and the name of the youth was George Burton and that of his canine companion Zip.
