Appleton, Victor – Tom Swift Jr 24 – And His 3D Telejector

Tom frowned. “Harlan, I don’t know what they were up to, but you’d better have that sign checked for clues of any kind.”

The conversation was interrupted as Miss Trent brought in a special-delivery letter. The envelope was addressed in green ink to Tom Swift.

“It just arrived,” she reported.

Tom tore open the envelope postmarked Shopton. The letter inside was printed by hand, also in green ink. Tom’s eyes widened as he read: CALL OFF YOUR 3-D PROJECT IF YOU WANTTO STAY HEALTHY, SWIFT. THIS IS THE ONLY WARNING YOU’LL GET!

CHAPTER VI

REVOLVING EARS

TOM handed the letter to Ames. The security chief scanned it quickly, then looked up with an angry frown. “What do you think, Tom? Another move by Sturko’s outfit?”

The young inventor shrugged. “Could be-but I have a feeling it’s more apt to be tied in with that phone call I got yesterday.”

“The one offering to buy your new TV system?”

“Right. Have you turned up any leads on competitive television manufacturers?”

Ames shook his head. “Not yet, but I’ve hired some private investigators to help us cover the field.” Ames promised to check with the post office immediately and try to trace the threatening letter.

Tom and Bud had dinner at the Swift home. Mrs. Swift served fried chicken and hot biscuits, followed by strawberry shortcake. She smiled with pleasure at the boys’ hearty appetites, but as usually happened before one of Tom’s expeditions she was rather quiet.
