Part 3: The Extraction Sequence
Marcus adjusted his grip on the edge of the metal workbench, the metal creaking slightly under his weight. “I used my key,” he said, his voice dropping to a low, measured register. “I saw the system alerts from my phone upstairs. Clara left the temperature regulation valve open by three percent. I came down to salvage the batch before the cell line degraded. I ran a stabilization cycle to lock the sequence.”
Clara let out a short, sharp breath, her hands tightening around the edge of the sink. “The temperature valve has an automatic mechanical override, Marcus. It doesn’t need manual intervention. And if you stabilized the sequence, where is the product?”
“It failed during the stabilization,” Marcus said. He looked directly at David, ignoring Clara. “The sequence was already too degraded. I had to dump the inactive carrier material into a secondary containment sleeve to prevent it from outgassing in the main chamber. I didn’t want to wake everyone up for a failure.”
David did not look away from the tablet in Leo’s hands. “A containment sleeve,” David said. “Leo, check the inventory of the sleeves.”
Leo tapped the screen. “The box of containment sleeves has a physical weight sensor. It registers twenty-four units. The database shows twenty-four units were present yesterday. It still shows twenty-four units.”
Marcus’s chest rose and fell rapidly. He took his hand out of his jacket pocket, then immediately put it back in. “I didn’t use the standard lab stock. I used one of the test sleeves from my personal kit. The ones I keep in my bag.”
“The test sleeves from your kit are clear plastic,” Clara said, her voice steadying as she stepped forward. “The vector requires amber tinting to protect it from the fluorescent light. If you put it in a clear sleeve, you would have destroyed the DNA sequence instantly. You know the protocol.”
“I used what was available, Clara,” Marcus said, his voice rising slightly before he checked himself. “I was trying to save your work. I didn’t have time to run a search for the correct materials in the dark.”
David walked toward the metal cabinet, his heavy boots loud against the concrete floor. He pulled open the drawer containing the amber tubes, counting them with a gloved finger. “Every amber tube in this drawer is sterile and empty. If you saved the sequence, Marcus, it is not in the drawer. If it failed and you put it in a clear sleeve, the residue would be in the biohazard bin.”
“I already told you, I put it in my bag to dispose of it safely,” Marcus said.
“Then show us the bag,” David said. He pointed to the leather satchel resting on the stool near the door.
Marcus did not move. He stood between the stool and the workbench, his shadow casting a long silhouette against the plastic sheeting on the garage wall. “My personal bag contains proprietary research from my day job. I’m not opening it.”
Leo looked up from the tablet. “The system log shows the 2:15 AM cycle didn’t run a stabilization program. It ran a product extraction sequence. That sequence only runs when a target molecule is successfully detected in the supernatant.”
Clara took a step closer, her eyes fixed on Marcus’s right jacket pocket, where the fabric sagged slightly under a small, solid weight. “He has it,” she said.
David turned slowly to face his cousin. “We have a choice, Marcus. We can cancel the investor call, declare bankruptcy on the garage, and let the creditors seize our personal assets. Or you can show us what is in your pocket.”
