Dave Dashaway and His Hydroplane Part 22

"So the old servant says. Gregg and Mr. Dale went away together.

There is no doubt in my mind that Gregg put up a plot to get Mr.

Dale away from Warrenton before we could expose him."

"But he could not keep Mr. Dale away from home forever?"

"No, but he and his accomplices might get the old man to some remote place and make him a prisoner."

"And force him to give up a lot of money before they let him go."

"Yes, that has been done before," admitted Dave.

"Anyhow, two days alter Mr. Dale left Warrenton, a check pa.s.sed through the bank signed by him for one thousand dollars."

Dave was both interested and alarmed.

"Four days ago a check for two thousand dollars arrived. The bank refused to cash it."

"Why, Mr. King?"

"Because it was a forgery."

"Not Mr. Dale's signature?"

"That's it."

"But where did the checks come from?" inquired Dave.

"From two cities, widely apart. I know the places. It looks to me as if the first check was given willingly by Mr. Dale. Then he must have become suspicious, and refused to pay out any more money. The second check was numbered correctly, and Gregg must have got possession of the old man's regular check book."

"This is a pretty serious affair, Mr. King," commented Dave.

"It is, and I came straight back here to tell you about it, and then cancel all my engagements at the meet. I shall start out at once to run down this Gregg and locate Mr. Dale."

"And I must join you-I see that it is my duty," declared Dave.

"Not at all," responded the aviator definitely. "I have mapped out the best plan of procedure, and I believe I can run down this business alone in a very short time."

Dave was really anxious concerning Mr. Dale. He truly believed it his first duty towards the old friend of his father to do all he could to a.s.sist him. For all that, Dave was relieved to know that he could go on without interruption in service of his employers.

"Yes," proceeded the aviator, "I feel that I have an interest in finding Mr. Dale. In the first place, he is your friend. Next, I feel responsible for letting that young scamp, Gregg, go free. At a selfish motive, I believe that if I succeed in rescuing the old man he will gladly finance my giant airs.h.i.+p scheme."

"He surely will, Mr. King," said Dave confidently. "I believe he would help you, anyway. I do hope he can be found."

"I shall not rest until he is," declared the aviator. "Now, Dashaway, I don't want you to take this affair on your mind. If I fail in what I have planned, I will certainly call you into the case. I fancy, from what Hiram here has told me, that you have some important business of your own on hand."

"Yes, that is quite true," replied Dave seriously.

"Are you having some trouble with the Interstate people?" inquired the aviator pointedly.

"Not on my account, I, am glad to say, Mr. King," replied Dave.

"There is some trouble, though, for all hands around. It's about the stolen aero-hydroplane, or hydro-aeroplane, they haven't just settled on the exact name."

"The Drifter?"

"Yes, sir."

"I read about that strange case. I suppose it puts you back in your arrangements at the meet here?"

"Not only that, Mr. King," explained Dave, "but it has placed me in a position where I shall have to give up all my engagements for a time."

"Why, you don't say so, Dashaway?" exclaimed the aviator, much disturbed.

"Those are the orders," replied Dave. "I have hurried back to Columbus purposely, to consult on your helping in a search for the Drifter."

"Of course that is not possible, now that this Dale affair has come up," said Mr. King. "As to a search for the stolen aircraft, that is going to be no easy task, I'm thinking. Have the Interstate people no theory as to the way the Drifter was stolen, and the motive for the theft?"

"I had better tell you all I know about it, Mr. King."

"Do so, Dashaway."

Dave proceeded to relate his interview with Mr. Randolph, the manager of the Interstate factory. He did not refer just then to his experience with the tramp.

"It's a good deal of a puzzle," commented the aviator. "What is your plan?"

"Why, I expected that I could induce you to take charge of the search. As you cannot, I am thinking of Hiram going back with me to Bolton."

"What's your idea?"

"The Interstate people have offered me their best monoplane to start the chase for the missing Drifter."

"It will be a blind start, Dashaway, without a clew."

"But I have a clew," announced Dave.

"You didn't say so."

"I hadn't come to that yet, Mr. King. I haven't even told the Interstate people. I am pretty certain that the Drifter left Bolton on a due northwest course," and Dave drew from his pocket the card he had got from the tramp.

"Capital!" cried the aviator, becoming very much interested. "If you know that, you have half solved the problem."

"Besides that," went on Dave, producing the duplicate N. A. L.

badge, and glancing at the scratched initials on its back, "I know who stole the Drifter."

"What's that?" almost shouted the aviator, springing to his feet, in a great state of excitement.

"Say, Dave, are you sure?" pressed the eager Hiram Dobbs, worked up to fever heat with curiosity and suspense.

"Who was it?" asked Mr. King.
