The precinct was chaos. Phones rang off the hook. Screens flickered with reports of panic across Halcyon. Citizens poured into the streets, fearful of what the Cipher’s broadcast meant.Inside the task force war room, the atmosphere was no calmer. Officers barked into radios, analysts pored over feeds, and the Commissioner’s voice thundered through the noise.“Shut it down, now! I want that signal traced, I don’t care if you have to burn every server between here and the damn moon!”Adrian stood back from the frenzy, his gaze fixed on the static-filled monitor. He heard Elias’s words replaying over and over in his mind: Keep up, Adrian.Beside him, Iris crossed her arms, her expression grim. “He’s not just taunting anymore. He’s declaring war.”Adrian said nothing. Because she was right.They retreated to a quieter corner, away from the shouting. Iris’s sharp eyes didn’t let him breathe.“You should’ve told me sooner,” she said, voice low but cutting.Adrian rubbed the back of his nec

The rumble of the city above was faint here, muffled beneath layers of rusted steel and dripping concrete. Adrian’s boots echoed as he followed Iris into the abandoned subway tunnels. Their flashlights cut weak beams through the dark, illuminating graffiti-smeared walls and discarded syringes. Rats skittered ahead of them, vanishing into cracks.“This place reeks of death,” Iris muttered, pulling her jacket tighter. “Remind me again why we’re here?”Adrian’s fingers tightened around his notebook. The latest cipher had pointed them here — not with words, but with coordinates hidden inside a grid of numbers carved onto the second victim’s skin. The pattern was unmistakable.“Because this is where he wants us to go,” Adrian said. His voice echoed off the tiles.Iris shot him a look. “You say that like you know him.”He didn’t answer. He just kept walking.The tunnel forked. Adrian crouched, running his fingers over a smear on the wall. Dried blood, brushed deliberately into a curve — not

The cathedral swallowed every sound, as though the building itself held its breath. Rain tapped against shattered stained glass, dripping into puddles on the stone floor. The laptop glowed like a lone beacon on the altar, bathing the nave in cold, artificial light.Adrian stepped forward, ignoring the tremor in his hands. Iris stayed back, her weapon raised, eyes scanning the cavernous dark.The screen pulsed. A timer appeared above the cipher:01:00:00Exactly one hour.The synthesized voice hissed from the speakers again.“Decode, or another life ends. Every second wasted brings you closer to failure, Adrian.”Adrian’s jaw clenched. His stomach knotted. He’d seen ciphers used as tools of control before—but this was weaponized math.He slid onto the altar, eyes scanning the spiraling code. Symbols layered over symbols: runes, glyphs, fragments of his own early designs. The killer had evolved them, mutating his work into something monstrous.“This isn’t just a puzzle,” Adrian muttered

The silence in Iris’s car was heavier than the storm rumbling outside. Rain lashed against the windshield as she drove them back into Halcyon’s core, neon signs bleeding into the wet glass like distorted runes.Adrian sat in the passenger seat, hands clenched so tightly that his knuckles were bone-white. His clothes were torn from the warehouse fight, his hair damp with sweat and grime. But what weighed heavier than exhaustion was the way Iris looked at him—like he was both an asset and a threat.Finally, she spoke.“You didn’t tell me the killer knew your old system.” Her voice was low, edged with steel.“I didn’t think—”“Bullshit.” She cut him off sharply. “Back there, in the warehouse—you knew what those ciphers meant before you even touched them. And the killer left a message for you. That doesn’t happen by accident, Cross.”Adrian exhaled shakily, staring at the rain-smeared streets. “Iris… if I told you everything, you’d drag me in as a suspect before you listened.”Her knuckle

Adrian’s knuckles whitened around the phone, Nina’s broken voice still echoing in his head.“Adrian… twelve hours…”The city’s night air pressed against him, sharp and cold, but inside his chest, heat boiled like molten iron. He wanted to smash the phone, scream at the streets, drag Kaine from the shadows with his bare hands. But he forced himself still. Rage was useless without focus.Iris’s hand touched his arm—steady, grounding. “We move now. Kaine just gave us the clock. That means his second key is in play.”Adrian’s jaw tightened. “Then let’s crack it before he writes the ending.”They hurried back to Iris’s car. Adrian spread the blurred city map from the photo across the dashboard, overlaying it with his own sketches.“The bomb was the first key—placed at a site from Halcyon’s old grid. If the pattern holds, the second key will be another historical pressure point.”Iris studied the lines. “So where’s the symbol from the tunnel feed?”Adrian pulled up the still frame he’d save

The image of Nina burned in Adrian’s mind, but his eyes kept drifting to the blurred background—the crude map of Halcyon marked with strange symbols.“The city itself is the code,” Kaine’s message had said.Adrian enlarged the photo, tracing the marks with his fingertip. “These aren’t random placements. They line up with the old city grid, pre-redevelopment.”Iris frowned, crouched beside him under the pier’s shadows. “Meaning what?”“Halcyon wasn’t built cleanly. The original grid from the 19th century was overlaid with modern zoning. Kaine’s symbols… they’re sitting on fault lines where the old city still bleeds through.”Iris tilted her head. “So these are… locations?”“Yes. But not just locations. They’re pressure points. If Kaine’s mapped out all these sites, then he’s planning something massive.”Adrian’s pulse hammered. He looked at Nina’s terrified eyes in the photo. “This isn’t just about her. He’s using her as leverage—to drag me into his bigger puzzle.”Iris stood, pulling
