Rocky Crawfish's hand twitched on the gleaming brass handle of the oversized door, his palm sweaty as he pushed into the lobby of the Metropolitan Surveillance Bureau. He took a tentative step inside, eyes darting. The room buzzed with agents crisscrossing like electrons, the air crackling with urgency. He caught snatches of hushed conversation, each word wrapped in mystery.

"Deep cover...satellite intel..." an agent muttered into her headset as she whisked by.

"Encryption levels are through the roof," another said, fingers flying over a tablet screen.

Rocky's gaze swept across walls lined with monitors flashing maps and data streams. His heart did a jitterbug. He felt like a kid who'd stumbled into a secret club - except this one had the fate of nations tucked in its back pocket.

"Excuse me?" Rocky ventured, approaching the reception desk where a man loomed like a storm about to break. This had to be him. The MSB Director – a human fortress in a charcoal suit.

"Director, sir." Rocky's voice squeaked out more like a question than a greeting.

The Director didn't smile; it wasn't in his repertoire. Instead, he appraised Rocky as one might assess a questionable piece of art.

"Agent Crawfish, is it?" The Director's brow arched ever so slightly, his eyes laser beams of scrutiny.

"Rock, actually." A nervous chuckle slipped from Rocky. "But you can call me Agent Crawfish if that floats your boat."

"Boats," the Director deadpanned, "are not my concern. Agents staying afloat, however, are." He glanced down at a file on the reception counter, then back up at Rocky. "You're late."

"Ah, well, you see, there was this cat in a tree and—"

"Save it. We have work to do."

"Of course." Rocky's Adam's apple bobbed in a dry swallow. It seemed his charm offensive would need rearming if he was to survive under the watchful eye of this stern gatekeeper.

"Agent Crawfish," the Director beckoned, his voice not just filling the space but owning it. "Over here."

Rocky shuffled over, shoes echoing a staccato rhythm against the polished floor. His gaze darted between the Director and the symphony of screens and gadgetry that adorned the walls.

"Welcome to the nerve center of global security," the Director began, arms opening as if to embrace the complexity around them. "The MSB doesn't just watch; we predict, we prevent."

"Predict and prevent," Rocky echoed, nodding so vehemently he feared his head might unscrew. "Got it."

"Every agent here plays a crucial part in a machine greater than themselves." The Director's eyes were steely, unblinking.

"Like cogs," Rocky said, then winced. "Or... not cogs? More like... uh, important... machine parts?"

"Indeed." The Director's face was a study in granite. "The point is, you are now part of this. Your actions carry weight."

"Weighty actions. I can do weighty." Rocky's laugh sounded strangled, even to his own ears. He cleared his throat, trying to dislodge the nerves lodged there.

"Your levity is noted, Agent Crawfish." The Director's tone suggested notes weren't necessarily a good thing. "But understand, our work is grave."

"Grave, yes. Not a laughing matter. No sirree." Rocky's smile faltered under the Director's piercing gaze. "I'm ready to be... grave. Seriously."

"Good." The word cut through the air, a knife slicing tension. "You'll need to be."

"Agent Crawfish."

The voice sliced through Rocky's reverie, sharp and immediate. He spun on his heel to see a woman with eyes like flint and posture that spoke of countless covert operations. Her hair was pulled back in a no-nonsense ponytail, and her gaze was appraising, critical.

"Agent Cassie Cole," the Director introduced. "She knows MSB's corridors better than her own pockets."

"Seems practical," Rocky quipped, offering a hand that hung awkwardly in the air between them.

"Practical saves lives," Cassie said, ignoring the gesture, her words clipped as if cut from the same stone as the Director's façade. "Humor can kill just as easily."

"Guess I should avoid cracking jokes at funerals then," he replied, retreating hand morphing into a self-conscious rub at the back of his neck.

"Especially at these funerals," the Director interjected, drawing their attention to the gravity awaiting them. "We've lost agents, Crawfish. Not to chance, but systematically. Someone is targeting MSB."

"Targeting?" Rocky's humor wilted under the starkness of the situation.

"Three dead in two weeks," the Director continued, voice grim as the final verse of an elegy. "All under mysterious circumstances. You're fresh eyes. Outside thinking."

"Outside... Right." Rocky swallowed hard, feeling suddenly like a pawn facing down queens and knights.

"Your mission," the Director said, locking eyes with him, "is to find the thread before we unravel further."

"Find the thread," Rocky repeated, his thoughts racing. "Unravel the mystery."

"Exactly." The Director nodded, and for a moment, his stern mask seemed to appreciate Rocky's turn of phrase.

"Keep your wits sharp and your jokes sharper," Cassie advised dryly, her eyes softening just a fraction. "You'll need both if you're going to survive here."

"Survive," Rocky echoed, the word tasting like a challenge on his tongue. "I'm good at that."

Rocky's chest swelled with a mix of pride and fear as he stood, nodding more fervently than he intended. "I'm on it," he declared, the words a buoy in the sea of his bubbling anxiety.

"Good." Cassie was already turning, her stride back businesslike. "This way."

He followed her through the labyrinthine corridors of the MSB, each step echoing his internal seesaw between eagerness and dread. The walls were adorned with maps and screens that flickered with data streams he couldn't yet comprehend.

"Interrogation rooms," Cassie pointed out, her thumb jerking toward a row of doors without breaking pace. "Mostly soundproof."

"Mostly?" Rocky quirked an eyebrow.

"Let's just say you'll know if someone hits a high C."

"Got it. Avoid opera singers." He winced at his own jest but couldn't suppress the quip.

Cassie shot him a look that could have been amusement or annoyance—it was hard to tell—and continued the tour. "Tech lab there. If it beeps or blinks, Briggs has poked it."

"Or made it beep louder," a voice chimed in from behind a door emblazoned with warning stickers.

"Briggs!" Cassie called without looking back. "How's the sonic decrypter?"

"Only shattered two mugs today!"

"Progress," she muttered, steering Rocky onward.

"Training rooms down here," she said, gesturing broadly. "Sutton practically lives in them."

"Sounds intense."

"Vic doesn't do 'halfway'." Cassie paused, her gaze sharpening. "You won't either, if you're smart."

"Full throttle, got it." Rocky flexed his fingers, imagining the weight of a weapon he had yet to hold.

"Here we are." She stopped before a nondescript door, its surface scuffed from years of service. "Your new home away from home."

"Looks... cozy." Rocky pushed it open, revealing a compact office dotted with aging tech and files stacked like miniature skyscrapers.

"Cozy is one word for it." Cassie lingered by the door. "Make it work, Crawfish."

"Always do." He flashed a grin, stepping into the space that would become his command center in the hunt for a killer amongst them.

"Remember, eyes open, mouth mostly shut." Cassie's parting words came with a rare twitch of her lips—a smile perhaps?

"Mostly," Rocky echoed, heart racing as the door clicked shut behind him. Alone in his new office, excitement surged over trepidation. This was his chance, the mission that would define Agent Rocky "Rock" Crawfish. And he was ready to prove himself.
