Tom Swift and The Visitor from Planet X

Bud Barclay, a dark-haired young flier and Tom Swift Jr.'s closest friend, chuckled. "If anyone can get the bugs out of your new invention, genius boy here will do it!"

Tom and Bud were bursting with curiosity. Although the Swifts had been in radio contact with creatures from outer space for many months, this was the most exciting news yet!

By this time Tom had recovered from his surprise and coolly sized up his enemy. The man was about thirty years old, with close-cropped black hair. Steely eyes glinted in a lean,...

Tom was appalled at this new danger. Shoving his drawing board back into its wall slot, the young inventor hurried to his desk and made a number of telephone calls.

As the trooper's flashlight stabbed through the cellar gloom at the spot where Bud had disappeared, there came a loud splash! The light showed a round hole in the floor, rimmed...

"Reports just in say that Brungaria has been taken over by a rebel group. Military aid to support the rebel coup is pouring in from Maurevia, Brungaria's powerful province in th...

Minutes went by before the signal bell rang on the electronic brain. Both Tom and Bud dashed over to the machine as it began to spell out the incoming message on tape:

The next morning Tom was up at the crack of dawn, grimly determined to find an answer to the earthquake menace. He ate a hasty breakfast, then drove to his private laboratory at...

Both boys were a bit shaken by the accident, nevertheless. Chow came rushing in as Bud was brushing the fragments of debris from Tom's clothes and examining the young inventor's...

"Don't be silly! Snap out of it!" Bud gave his pal a cheerful poke in the ribs, hoping to buck him up. "You heard what Blake said--Washington itself was hardly touched. Without...

Tom was thoughtful for a moment, frowning as they watched Ole Think Box continue its gyrations. The figure seemed to be calming down somewhat, although Tom could not be sure of...

A strange sight greeted Tom's and Bud's eyes. In the first rays of sunlight, the space robot was moving back and forth about the laboratory in wild zigzag darts and lunges.

"It's bad enough that an enemy was able to get the information," Mr. Swift remarked. "But, potentially at least, it's even more dangerous that he was able to imitate my voice so...

Both Tom and Mr. Swift were shocked by this latest blow of their enemies. Tom called Ned Newton at the Swift Construction Company at once and told him the news.

Mr. Swift, beaming with pride, gave Tom a quick hand-squeeze. "It's an amazing achievement, son. And it may prove to be the key for unlocking the secrets of space, if and when w...

Tom's maneuver had carried them a good hundred yards off the missile's course. Now he yanked a lever, pulling the cadmium rods still farther from the atomic pile, in order to in...

Mr. Swift looked on eagerly as Tom explained and demonstrated his touch apparatus. By moving a pantograph control, Tom was able to manipulate the claws like a hand with fingers....

But the waiting seemed endless. Bud's eyes met Tom's. The flier grinned and held up crossed fingers, just as Tom had done to Mike Burrows the previous evening. Tom managed a fee...

A chill of fear gripped Tom and his companions as they blinked helplessly in the glare! Had the enemy detected them the first moment they had set foot on Balala Island? Had they...

The elder scientist was feeling Tom's wrist. "His pulse is beating, but it's a bit weak. He must have received a terrific shock from all that energy!... Tom!... Tom, son, can yo...
