Unbeknownst to Martha and Levi Keach, their conversation was being monitored by someone from the inside of an old nonfunctioning air conditioning unit that was left there for decades. The inside was hollow, and it hid a secret door where someone who knew this strategic hiding place can peek through what was going on inside the laboratory. A shadow that breathes slowly quietly listens as it memorized the steps Levi was typing on the computer.
The small tv like computer screen just announced that the program was now fully functioning and it offered them back to the same menu, but this time it unhides the new button that was not there before.
"Open door?" Matha buzzed.
Levi just stared at the computer monitor.
"This could be the door to the possibilities of the 4th dimension."
Martha was gripped with excitement. "Then, that equation did it for us."
