Jerry consulted his clipboard. Today's inspection route would take him through Section D-7, one of the oldest parts of the system dating back to the 1920s. That section always required extra attention—the pipes there were temperamental, prone to pressure fluctuations that could be either a minor annoyance or a major problem depending on what the gauges said.
He moved through the tunnels with practiced efficiency, checking pressure readings at each junction box, noting temperatures, looking for signs of leaks or structural issues. The heat was oppressive but manageable, something he'd long since acclimated to. Some of the newer guys couldn't handle it—they'd last a month or two before transferring to street maintenance or snow removal, anything that kept them above ground. But Jerry had never minded. There was something peaceful about the tunnels, something almost meditative about the isolation and the steady hiss of steam through pipes.
At Junction D-5, he paused. His digital thermometer was reading higher than it should—138 degrees Fahrenheit when the system was calibrated for 125. Not dangerous yet, but unusual enough to warrant investigation.
Jerry pulled out his radio. "Walsh to dispatch."
Static crackled, then Cindy's voice came through, bored at this early hour. "Go ahead, Walsh."
"I'm showing elevated temps in Section D-7, Junction D-5. Nothing critical, but I'm going to trace it back to see if we've got a valve issue."
"Copy that. Log it when you're done."
He clipped the radio back to his belt and consulted the schematic he'd brought, though he barely needed it. The elevated temperature was probably coming from the D-8 branch, which fed into some of the older buildings near the waterfront. That section had given them trouble before—old valve assemblies that didn't always seat properly, pipes that had been patched so many times they were more solder than original steel.
Jerry followed the main line deeper into Section D-7, where the tunnels grew narrower and the bulbs were spaced farther apart. This was the part of the system that made the new guys nervous—tight corridors, older construction, areas where you couldn't always stand upright. But Jerry had been coming down here since before some of those kids were born. The tunnels might be old, but they were solid. Built to last.
The temperature climbed as he progressed, going from oppressive to genuinely uncomfortable. Jerry loosened his collar, wiping sweat from his forehead. The thermometer now read 145 degrees. That was definitely a problem—sustained temperatures that high could damage the insulation, create safety hazards for anyone working in the area.
He reached Junction D-8, where the corridor split into two branches. The heat was radiating from the left branch, the one that serviced the old maritime buildings down by the port. Jerry hesitated, checking his watch. 5:23 AM. He could radio it in, wait for someone else to investigate during regular hours. But that would mean leaving a potential problem unattended for hours, and in his experience, small problems in the tunnels had a way of becoming big problems if you ignored them.
Besides, he was already down here. Might as well take a look.
The left branch was narrower, forcing Jerry to duck slightly as he moved forward. The pipes here were older, wrapped in asbestos insulation from decades past that they'd encapsulatedrather than removed—safer that way, as long as nobody disturbed it. The heat was intense now, making the air shimmer slightly in the beam of his flashlight.
Something felt wrong. Jerry couldn't articulate exactly what, but after thirty-two years, you developed instincts about these things. The tunnels had a rhythm, a normal pattern of sounds and smells and ambient conditions. This felt off.
The corridor opened into a small maintenance chamber, one of dozens scattered throughout the system. This one serviced the old valve array for Buildings 14 through 17, buildings that had been converted from warehouses into office space back in the eighties. Jerry had been down here countless times, knew every inch of it.
But he'd never seen it like this.
The heat was overwhelming, radiating from the pipes with an intensity that seemed impossible. His thermometer maxed out at 160 degrees and was still climbing. And there, slumped against the far wall beneath the main steam line, was a shape that Jerry's brain initially refused to process as human.
"Jesus Christ," he whispered.
It was David Langford. Jerry recognized him despite everything—recognized the Public Works uniform, the distinctive silver watch David always wore, the wedding ring on his left hand. David was a pipe fitter, worked the day shift, good guy who always had photos of his kids ready to show anyone who'd look.
But David looked wrong. His exposed skin—face, neck, hands—was covered in strange burns, red and blistered in patterns that didn't make sense. Not like he'd touched something hot, but like the heat itself had reached out and marked him. His eyes were open, staring at nothing, and his mouth was slightly agape as if he'd been trying to speak when he died.
Jerry stumbled backward, his boot catching on an uneven section of concrete. He caught himself against the wall, the metal pipe burning his hand through his work glove. He yanked his hand back with a curse.
His radio. He needed his radio.
Jerry fumbled for it with shaking fingers, his thumb slipping on the transmit button. The heat was making it hard to breathe, hard to think. What the hell was David doing down here? The pipe fitters didn't work night shifts, and even if they did, nobody came into the steam tunnels alone. That was basic safety protocol, drilled into every employee from day one.
"Dispatch," Jerry gasped into the radio. "This is Walsh. I need... I need emergency services to Access Point 7 immediately."
"Walsh? What's wrong?" Cindy's boredom had vanished, replaced by sharp concern.
"I found David Langford. In the D-8 maintenance chamber. He's..." Jerry's voice cracked. "He's dead. And there's something wrong with the heat down here. Something really wrong."
"Are you in danger? Do you need to evacuate?"
Jerry looked back at the chamber, at David's body slumped beneath those impossibly hot pipes. The rational part of his brain catalogued details automatically—the way David's uniform was soaked with sweat, the position of his body suggesting he'd collapsed rather than been placed there, the complete absence of any tools or equipment that would explain why he'd been down here in the first place.
"I'm moving back to the main corridor," Jerry said, already backing away from the chamber. The heat was unbearable, making his vision swim. "But you need to get someone down here. Police, paramedics, I don't know. Just get someone."
"Copy that. Stay on the radio, Jerry. Help is coming."
