Part 1
Part 2
Thomas Lionel, a physicist freshly triumphant after outwitting an over‑bearing engineer, wakes to a day that seems almost too perfect. Over breakfast he debates the latest theories on multi‑resonant wave guides, while his mind drifts between chess strategies and the uneasy balance of their uneasy partnership. The routine is shattered when a sleek, three‑wheeled “sky car” lands on his lawn, its name—Poltergeist—hinting at the uncanny technology it carries.
The vehicle’s driver, a pragmatic courier named Jim, explains that the contraption is a prototype capable of hovering without conventional wings or rotors. Intrigued and cautious, Thomas is drawn into a covert test that could rewrite the rules of propulsion, yet the engineer’s hidden agenda looms large. As the sun glints off the strange machine, Thomas must decide whether to help refine this breakthrough or watch it slip through his fingers.
