"You knew?"

"One of the troopers sent a short-wave message you were safe and Donner captured."

"But Chet . . . What . . . ? How . . . ?" Frank stammered.

"Nothing to be amazed about," said Chet as the others, grinning, made a place for Frank at the table. "Old Chet went for the police and brought 'em back, that's all!"

"But the smashed car-you weren't in it?"

"Right! Just a little detective's trick." The stout boy shrugged with attempted modesty. "I had a head start on that hijacker, so I hid the convertible in some trees near that jalopy we saw. I put in a blanket, set the old crate on fire, and shoved it over the bluff."

175 Chet beamed. "Did it burn! That Socky thought I was in it. I waited till he'd gone, drove on down Rim Road without lights, and called the State Police from the first house with a phone. Told 'em to come ready for a wild animal as well 58 as criminals. When they got here I showed the police the secret chute and the cabin. They did the rest, and rounded up all the crooks."

"You're a real trooper for sure," Frank said. "We couldn't solve a mystery without you."

This proved to be true in the boys' next case, THE VIKING SYMBOL MYSTERY.

"As for me," Fenton Hardy took up the story, "I hurried over here from New Jersey right after I quizzed that pair you boys caught in the station wagon.

Just by luck, I was at the State Police barracks when Chet's call came in."

"This is the gang you've been after, then?" Frank asked.

"Sure is," his father answered, "and they're all behind bars now. Webber's shoes matched the cast taken by Sheriff Ecker-so he confessed to setting the cabin on fire, hiding nearby, and seeing you boys escape. We found the cache of hijacked goods in two of the underground pa.s.sages.

"Webber has also confessed to selling everything but the missile nose cones as property of fict.i.tious companies which were going out of business. A clever racket he worked with an auctioneer in New York City."

176 Joe added, "And he was holding up the settlement of the Donner estate until he and Walter had disposed of all the hijacked goods. The gang confessed they did take that hound dog, and kept it for their own use. Socky was the one who spied on us in the woods, and also on Webber. Donner didn't even trust his own men. By the way, William and his sister are innocent of any part in the racket."

"Well, my job's over now," concluded Mr. Hardy. "And you three boys did the major part of it for me. Which means you get the major share of the credit, and the major share of the reward money, too!"

"And they certainly deserve it!" Captain Maguire put in fervently.

"My share's going to Simon," Frank declared immediately. "Dad, perhaps his voice could be restored through surgery!" Joe and Chet instantly seconded Frank's decision.

"I'm sure medical science can do something," Fenton Hardy answered. "Some very successful mechanical speaking devices have been developed, if it should turn out his voice can't be restored in any other way. In any case, we can send him to art school. I understand he has a fine talent for drawing."

"That's for sure," said Chet with admiration, as Simon's eyes shone with grat.i.tude. "I'll have all the reward I want out of this case if I can keep Mystery. But say, I want to make sure Miss Donner gives back Skippy to little Bobby Thompson!"

"It'll be done, Chet," Mr. Hardy promised.

"That leaves just the puma," said Joe. "We'll give him to a zoo. They can put up a sign over its cage: This Animal Was Once Known and Feared As the Screaming Witch of Black Hollow'

"How about adding a couple of owls?" Chet suggested. "Boy, that screeching really gave me the creeps!"

THE END.
