The stairs down to the abandoned platform smelled of rust and something else. Something sweet underneath, like overripe fruit left too long in a bin. Harlow Quinn clicked her torch on and swept the beam across the curved tile walls. Posters from 1962 peeled in long strips. A rat scuttled into a crack. "Down here, Detective." The voice echoed up from the platform below. Sergeant Webb had gotten the call forty minutes ago and beaten her to the scene by fifteen. She'd spent those fifteen stuck in traffic on Camden High Street, watching buskers and tourists stream past, none of them knowing what lay beneath their feet. She descended. Thirty-two steps. She counted them without thinking, the way she'd counted steps for eighteen years on the force. Her left wrist caught the torch beam as she moved. The leather strap of her watch had cracked again. She'd need to replace it soon. The body lay near the old ticket barrier. A man, mid-fifties, grey hair matted against the platform. Face down. One arm stretched out as if reaching for something. Webb stood over him with a notepad, his young face pinched in that way new detectives got when they'd seen three bodies and thought they understood death. "Mugging gone wrong, looks like. Wallet's gone, phone's gone, watch is gone." Quinn crouched beside the body. She didn't touch it yet. Just looked. The man's shoes caught her attention first. Loafers. Good leather, recently polished. Small scuff on the right toe, nothing on the left. The kind of shoes that cost more than Webb made in a week. "These aren't Camden shoes." "Pardon?" "His shoes. His coat too." She nodded toward the dark wool overcoat bunched around the man's shoulders. "Savile Row cut, or close to it. This man didn't come down here to catch a Tube that doesn't run anymore." Webb flipped a page in his notepad. "Could be lost. Could be meeting someone. Wealthy types come to Camden for all sorts, don't they? Drugs, women—" "Then where's his car?" The question hung between them. Webb's pen stopped moving. "I've had uniforms check the streets above. No abandoned vehicles matching what we'd expect. No taxi records. No Uber drops in the last three hours within two blocks." Quinn stood, her knees popping once. "A man in a four-thousand-pound coat doesn't walk from Mayfair to an abandoned Tube station." She moved her torch along the platform. The original tiles had held up well, all things considered. Dark green with a cream border. Some graffiti newer than others. A tag in red spray paint. A stencil of a rat wearing a crown. And then, near the far end where the tunnel mouth gaped black, something scratched into the tile. She approached it, boots crunching on debris. "What've we got here?" Webb followed. "Vandalism, probably. Kids break in all the time. There's a whole community of urban explorers—" "This isn't vandalism." The scratches formed a symbol. Circular, with lines radiating outward at uneven intervals. Not carved with a key or a knife. The grooves were too precise, too deliberate. She'd seen markings like this before, three years ago. In the basement of a warehouse in Docklands where DS Morris had drawn his last breath. The case file had listed them as "unknown origin, possible gang signs." She'd believed that. She'd had no reason not to. "Webb, get forensics down here. I want photos of this symbol from every angle." "Ma'am, if this is just—" "Did I stutter?" He flinched. She watched him pull out his radio and make the call, watched him walk a few paces away to give himself privacy from the crazy woman who wanted forensics to photograph graffiti. Let him think she'd lost the plot. She'd lost it years ago. The question was whether she was finding a different one. She returned to the body. Crouched again. This time she pulled on nitrile gloves and lifted the man's coat collar. No wallet, no phone, no watch. Webb had noted all of that. But Webb hadn't noted the marks on the man's neck. Four small punctures, arranged in a semicircle. Not a knife wound. Not a human bite. The skin around each puncture had turned black, the discoloration spreading in thin lines like roots from a plant. "Webb." He looked up from his radio. "When you rolled him over to check for ID, did you notice these?" He approached, squinted. "Bruising, maybe? If he fell—" "Four puncture wounds in a semicircular pattern, each exactly two centimetres apart, with necrotic spreading that suggests some kind of venom or chemical agent." She let the coat drop. "Does that sound like a fall to you?" Silence. His notepad hung loose at his side. "I'll get the pathologist to—" "I want Dr. Achebe specifically. Not her junior, not whoever's on rotation. Achebe." "You're going to have to justify that to the super." "Then I'll justify it." She stood and swept her torch across the platform again. The beam caught something near the wall, half-hidden beneath a discarded newspaper. A small object, brass-coloured, catching the light. She crossed to it in four strides and picked it up. A compass. Old, with a patina of verdigris across the casing. The face was etched with symbols she didn't recognise, patterns that seemed to shift when she tilted it. The needle inside didn't point north. It pointed toward the tunnel mouth, trembling slightly, as if whatever lay at the other end pulled at it with invisible hands. "What's that?" Quinn closed her fingers around the compass. The metal was warm against her palm. Warmer than it should have been, sitting on a cold platform in an abandoned station. "Evidence." "Looks like junk. Some old compass—" "Bag it." Webb produced an evidence bag from his kit, holding it open. She dropped the compass inside and watched the needle continue to point at the tunnel, even through the plastic. "Run the victim's prints through the system. If he's wearing clothes like that, someone's reported him missing." "And if no one has?" Quinn turned to face him. Her jaw tightened. "Then we've got a bigger problem than a mugging gone wrong."
