ECHO CHAMBER

Chapter 2 – Echoes in Darkness

The quiet click of Echo's nails against the polished concrete floor preceded James Harlow into the gleaming halls of Cyberscape Solutions. He'd remembered the layout months ago—twenty-three steps from the elevator to reception, a sharp right bend, and another seventeen feet to his office. Echo, a golden retriever with great training and awareness, guided him expertly despite the always shifting obstacle course of standing desks and programmers' backpacks.

"Morning, James!" yelled Natalie from reception. "Coffee's fresh, and your nine o'clock is already waiting in your office."

James flashed his most disarming smile in what he hoped was Natalie's approximate direction. "Early bird gets the vulnerable server, I suppose." He adjusted his dark spectacles, a habit from when he'd first lost his sight. "Any calls worth mentioning?"

"Just the Bureau again. Third time this week."

James's smile slipped somewhat. The Federal Analysis Bureau has been insistent lately, something about consulting on a specialized situation. He'd been similarly relentless in avoiding them. A government job involved paperwork, restrictions, and explaining his methods to people who rarely understood them.

"Still reviewing those, Nat. Thanks for running interference."

Echo steered him past what sounded like an intern carrying too many electronics. James could hear the slight electrical whine of at least three computers and what was certainly the unique buzz of a badly insulated tablet. The sounds formed a detailed aural world that most people couldn't begin to grasp.

In his office, James immediately detected the presence of his client—expensive cologne (sandalwood with a hint of bergamot), the soft creak of Italian leather shoes as the man shifted impatiently, the subtle electronic hum of a high-end smartphone, and beneath it all, the barely perceptible clicks and whirs of what was almost certainly a pacemaker.

"Mr. Riordan, I presume?" James extended his hand in the direction of the respiration. "Sorry to keep you waiting."

"How did you—" Riordan began, but halted himself. "Right?" Your helper must have told you."

James didn't correct him. Let consumers believe what makes them comfortable. Echo brought him to his chair, then nestled into her allocated seat by the desk.

"Your Secure Bank has experienced three penetration attempts in the last month," James stated, without bothering with small conversation. "Each is more complex than the last. Your security experts can't find the vulnerability, but they've traced unique audio irregularities during each try."

Riordan's heart rate raised slightly—James could hear the tiny change in his pacemaker's rhythm. "That information wasn't in the brief I sent over."

James smiled again, this time with genuine amusement. "No, it wasn't. But that's what you're coming to ask me about."

He reached for his keyboard, fingers finding the precise position without hesitation. His screen stayed dark—no need to waste electricity—but his specialist audio interface sprang to life, translating digital information into delicate tones and clicks that built a detailed image in his mind.

"The attacks happened at 2:17 AM, when server demand was modest. Your team identified no malware signatures, no unexpected data transfers." James inclined his head, listening to the pattern of clicks as his system examined the bank's security logs. "But there was something else, wasn't there? A sound that shouldn't have been there."

Riordan moved again, leather cracking. "How do you do that?"

James's fingers danced across the piano. "Before I lost my sight, I specialized in audio cryptography for military intelligence. Afterward, my hearing... adjusted. Evolved. I hear things others don't." He never discussed the explosion, the colleagues who hadn't survived, and the nightmares that still woke him in cold sweats five years later.

"The security system recorded an ultrasonic frequency during each attempt," Riordan finally conceded. "Our engineers say it's impossible—sound can't hack computers."

James chuckled, but there was no fun in it. "Your engineers need to refresh their education. Sound may undoubtedly effect electronic systems when correctly adjusted. Resonant frequencies can disrupt operations, even damage electronics. But this is something more complicated."

He plugged in a sophisticated audio gadget, tweaking settings by feel. "I need the original recordings from your security system."

As Riordan scrambled with his phone to transfer the data, James leaned back, absently rubbing behind Echo's ears. This was his element—translating the invisible world of sound into security solutions. Clients turned to him when conventional methods failed, when they needed someone who could hear what others couldn't.

The files arrived with a characteristic notification tone. James plugged in his earbuds—not because he needed privacy, but because the sounds he needed to examine would be unnoticeable or excruciating to regular hearing.

What he discovered made him sit up straight.

"Your intruder isn't using sound to attack your systems directly," he said after several minutes of hard listening. "They're utilizing highly tuned acoustics to trace the keystrokes of your security people. I can hear the distinct rhythms of password entries."

"That's impossible," Riordan objected.

"For most people, absolutely. For someone with highly sophisticated equipment and knowledge of acoustic analysis? Entirely plausible." James removed his earbuds. "They're listening to your security team type their passwords, then using the sonic signatures to reproduce the exact keystrokes."

He could have explained further—how different keys made microscopically varied sounds, how the timing between keystrokes created unique patterns—but clients often didn't care about process, only outcomes.

"I'll need access to your security center to install specialist dampening equipment. And your team requires retraining on audio security protocols." James named his charge, purposefully high.

Riordan didn't even negotiate. "When can you start?"

"Tomorrow morning," James stood, signifying the conclusion of the meeting. "And Mr. Riordan? You might want to have that pacemaker checked. The rhythm's a little uneven."

After Riordan left—stunned quiet by the pacemaker comment—James bent down to Echo. "Another day of making normal people uncomfortable with what we can do, girl." The dog nuzzled his palm sympathetically.

His phone buzzed with the particular pattern he'd allocated to Natalie. "The Bureau called again while you were in your meeting. They're sending someone over this afternoon. Said it's non-negotiable this time."

James sighed. "What's so important that they can't take no for an answer?"

He couldn't know that across town, a deaf acoustics specialist was seeing noises that shouldn't exist, colors and patterns that would eventually connect their lives in ways neither could understand.
