Chapter 14
Margaret sat in the common room at Shady Glenn, Spotty making his rounds from lap to lap. She’d come for her regular Friday afternoon visit, but her mind was still churning through the case. The IT contractor information Nick Liu had sent her led nowhere—a reputable firm with no apparent connections to activism or terrorism. Everything felt like running into walls.
“You look like you’re trying to solve world hunger, dear,” Linda observed from her wheelchair. Spotty had claimed his spot on her lap, and she stroked his fur absently.
“Just a case that won’t cooperate, hon.” Margaret rubbed her temples. “Every answer I find leads to three more questions.”
George wheeled himself closer. “The pesticide case?”
Margaret leaned back in her chair with a sigh. “I thought I had it figured out. The R&D director sent my client away the night of the theft. There’s proof of that. But he has an airtight alibi. He was in Philadelphia.”
“He could have sent the email remotely,” George suggested.
“That’s what I thought. But the email isn’t in his sent folder. Someone accessed his account and sent it, then deleted all traces.” Margaret spread her hands. “And the IT contractor who maintains their system is clean. No radical connections, no financial troubles, nothing suspicious.”
A nurse approached with a small paper cup of pills and a glass of water. “Linda, time for your afternoon meds.”
Linda made a face but accepted the cup. “Which ones are these? They keep changing them on me.”
The nurse checked her computer, frowning. “Your blood pressure medication and—wait, that’s odd.” She tapped the screen a few times. “The system says you already took your 2 PM dose.”
“I most certainly did not,” Linda said indignantly. “I’ve been sitting here with Margaret and these troublemakers all afternoon.”
“Let me check the paper log.” The nurse pulled a clipboard from the medication cart and flipped through pages. “Hmm. You’re right—nothing written down for 2 PM. But the digital system shows...” She shrugged. “Must be a glitch. Let me just correct it.” Her fingers moved across the screen. “There. Now it shows you didn’t take them yet. See? Just edit it right here, and it’s like it never happened. History rewritten. Go ahead, Linda.”
Linda swallowed her pills and handed back the cup. “Your system needs fixing.”
“Tell me about it,” the nurse said cheerfully.
Margaret sat very still. “You mean you can just go back in and edit any entry?”
“As long as you’re the administrator, anyway. Makes it look like it was always recorded correctly.” She moved on to her next patient, the medication cart squeaking down the hallway.
“Margaret?” George’s voice seemed to come from far away. “Are you all right?”
“As long as you’re the administrator,” Margaret repeated slowly. “You can just... edit the entry.”
Cheryl wheeled closer. “What’s got you so thoughtful all of a sudden?”
“The badge logs.” Margaret stood abruptly, startling Spotty. “Everyone’s been asking how someone cloned Sade’s badge. The IT firm said it was impossible. But what if no one cloned it?”
Four pairs of eyes turned to her.
“What if someone with administrator access just went into the system and changed what the logs say? Made it look like Sade’s badge was scanned when it wasn’t?” Margaret’s voice grew more animated. “Like the nurse just did. The digital system said one thing, but it was wrong. So she just... edited it.”
“That’s too simple,” Linda said. But she looked intrigued.
“Exactly!” Margaret was pacing now, Spotty trotting behind her. “Everyone’s been focused on how someone could beat such an elegant system. Sophisticated bypass, technical wizardry. But the answer isn’t elegant. It’s brute force. Direct manipulation.”
George’s fingers steepled. “Who has administrator access to those security logs?”
“Chris Webb. The security manager.” Margaret felt pieces clicking into place. “He manages the entire system. He could just open the logs and edit them. Write in that Sade’s badge was scanned when it wasn’t.”
“But the IT firm investigated,” Tony said, confused. “Wouldn’t they see that?”
“Would they?” Margaret pulled out her phone, already scrolling through her notes. “If someone edits a digital log cleanly enough, there might not be any trace. It just looks like the original record. Like Linda’s medication entry—once the nurse corrected it in the system, it looks like it was always recorded that way.”
“Except there’s the paper log,” Linda pointed out. “That nurse checked the clipboard and saw nothing was written down.”
Margaret stopped pacing. “Is there a paper log? For the badge system?”
George shook his head slowly. “Everything’s digital now. No paper backup.”
“Then there’s nothing to compare it against.” Margaret felt her pulse quicken. “Chris Webb could have edited those logs the night of the theft. Made it show Sade’s badge was scanned at 11:35 PM and 11:47 PM. And with the cameras conveniently down, there’s no video evidence to contradict it.”
“Why would he steal pesticides?” Cheryl asked practically.
“Money,” Margaret said. “It’s always money. Someone paid him to get into that storage room and take a specific container. He might not have even known what was in it or what it would be used for.”
Linda shifted Spotty on her lap. “So how do you prove he edited the logs?”
“I don’t know yet.” Margaret grabbed her briefcase. “But there has to be a way. Digital forensics, metadata analysis, something that shows the logs were tampered with.” She kissed her father’s forehead. “Thank you. All of you. That nurse just broke this case wide open.”
Tony beamed. “We helped solve a mystery!”
“You absolutely did.” Margaret scooped up Spotty. “Now I just have to prove it before the feds bury my client under terrorism charges.”
She hurried toward the exit, her mind racing. Chris Webb. Security manager with administrator access. The one person who could edit the security logs without anyone questioning it. And his alibi was the weakest of everyone involved.
Margaret reached her car and immediately called Katherine.
“Kat, I need a digital forensics expert. The best one you can find.”
“What’s going on?”
“The badge logs were edited. I’m sure of it now. Chris Webb didn’t need to clone Sade’s badge—he just changed the digital records to make it look like her badge was scanned.” Margaret started her car, adrenaline singing through her veins. “Everyone’s been so focused on this sophisticated security system, asking how someone could beat such elegant encryption. But the answer isn’t elegant. It’s simple—like a nurse editing a medication log.”
“Okay. Send Lee the AgroSynthetics security logs. If they were edited, he’ll find the proof.”
Lee Stewart, Katherine’s digital forensics specialist and one of the best in the business. Margaret felt relief wash through her. “How long?” She heard murmuring in the background.
“He says if the logs were tampered with, he’ll have evidence by tomorrow morning.” Katherine’s voice held quiet confidence.
Margaret pulled out of the parking lot. “Kat, we need Chris Webb’s financial records. See if there’s been any unusual deposits, large cash transactions, anything that suggests he was paid for this.”
“Jake can handle that. What about the terrorism connection?”
“I think it might be a red herring. Chris steals the pesticides, sells them for profit. He doesn’t know or care what the buyer plans to do with them.” Margaret navigated through traffic, her thoughts coming faster than she could articulate them. “He framed Sade to protect himself. Used her badge in the logs because she was the only other person with storage access who didn’t have an airtight alibi.”
“That’s conspiracy. Evidence tampering. Digital forgery.” Katherine’s voice sharpened. “If you’re right, Chris is looking at serious time.”
“Good,” Margaret said grimly. “Because my client is looking at life in federal prison for something she didn’t do.”
