The trial also showed him parts of Meridian he had never seen from the cleaning route. During the day, people filled the elevators with fast conversations and walked past repair workers as though maintenance were an interruption to the company's real purpose. Some were courteous and curious about a former cleaner joining the technical team. Others greeted him warmly until they read his new badge, then asked why someone without an engineering degree had been assigned to the floor.
Marcus had learned to answer without becoming defensive. "I'm in a supervised technical training position," he would say. "My background is commercial repair. I don't do work outside my qualifications, and I ask for help when I need it." Most people accepted the explanation. A few seemed disappointed that he did not claim to be a hidden genius who could solve any problem with a glance.
One afternoon he rode the elevator with Adrian Bell, who had not spoken to him since the night of the sensor failure. Adrian looked at his new badge and smiled in a way Marcus could not quite read. "Quite a change from cleaning offices," Adrian said. "The CEO must have been very impressed."
Marcus nodded politely. "I had an opportunity to demonstrate what I knew. I'm still learning the rest."
"That's good," Adrian replied. "Just remember we run a complicated operation here. One clever observation doesn't make someone a facilities manager." Marcus met his eyes in the reflected elevator glass.
"I know that, sir. I've never claimed otherwise." When the doors opened, Adrian stepped out first, leaving Marcus to wonder why the comment had been necessary at all.
Peter heard about the exchange later and sighed. "Adrian has built his reputation on never having a surprise reach the board," he said. "When you found that sensor problem, it made him look like he had missed something. He's probably trying to decide whether you're a useful hire or an embarrassment."
Marcus continued cleaning a multimeter probe with a dry cloth. "I don't need him to be embarrassed," he answered. "I need him to let us fix what needs fixing."
That distinction mattered more a month later when a routine review showed that Meridian's facilities team had replaced expensive control modules in several offices where the problem reports sounded almost identical. Leila found three cases described as intermittent high-temperature shutdown, two on another floor and one in a meeting suite that had been remodeled the previous year. The vendor notes concluded that controller boards had become unstable and recommended complete replacements. None included a record of a physical temperature comparison.
Marcus asked whether the vendor's conclusion could still have been correct. Peter said of course it could; the absence of a particular test did not prove the diagnosis wrong. But the pattern was troubling enough that they requested the old records and verified what could still be verified. In one location, a sensor had drifted out of calibration. In another, the original service contractor had documented a connector problem but billed for a full module replacement anyway.
