Detective Harlow Quinn stepped off the last usable stair and found a police cordon stretched across the mouth of an abandoned Tube platform. Beyond it, strip lights powered by a portable generator washed the old station in a hard white glare. Rainwater had eaten black trails down the tiled walls. A sign still promised trains to Mornington Crescent, though the rails had vanished beneath concrete decades ago. A brass bell hung from a hook beside the ticket booth. Rows of empty stalls filled the platform, their frames built from mismatched doors and lengths of pipe. Someone had painted prices on scraps of slate. The stall nearest Quinn offered TEETH, SORTED BY OWNER. Detective Sergeant Malik Voss lifted the cordon for her. “Tell me that’s an art installation.” “The lab called it a homicide scene.” “Before they saw the teeth?” “They’ve taken a sample.” Quinn passed beneath the tape. Her boots struck dry tile. A few yards on, they began to stick. The victim lay between two stalls, one crowded with stoppered glass vials, the other hung with tarnished mirrors. A woman in a grey coat, perhaps thirty, lay on her back with her hands open beside her. Blood spread beneath her head in a broad dark pool. Quinn stopped short of the body. A single shoe print crossed the blood and led toward the platform edge. “Whose print?” “Nobody’s admitting to it. First officers stayed by the ticket booth. Scene team came in from the far end.” “That leaves the killer.” “That’s one answer.” Voss stood with his notebook tucked under one arm. His sleeves were rolled above his wrists, exposing a narrow band of blue ink around the left one. Quinn had never got him to explain the tattoo. “Name?” “Dr Lena Farouk. Contractor for a conservation lab. Her flatmate reported her missing yesterday morning. We found her driving licence in her coat.” “Who found her?” “Two maintenance workers. They came down to check a power fault.” Quinn looked at the vials. Their contents ranged from cloudy yellow to a red so deep it looked black. Handwritten labels faced the aisle. SALT OF MERCY. WIDOW’S MILK. One jar held what appeared to be a human molar suspended in blue fluid. “Maintenance workers found their way through all this without touching anything?” “They used the old service access. Same way we came in.” “Did they call it in?” “One did. The other left before uniforms arrived.” Voss opened his notebook. “The caller gave us his mate’s name and number. Both false.” Quinn crouched beside the shoe print. It had a smooth heel, a diagonal cut across the sole, and a nick at the outer edge. At its centre, something pale had pressed into the blood. “Photograph that again.” “The scene photographer got it.” “From above. With a scale.” She pointed. “There’s a crescent in the tread.” Voss leaned closer. “Grit.” “Too regular.” Quinn rose and checked the woman’s shoes. Black ankle boots. Their soles carried a dense pattern of small diamonds. “The print isn’t hers. We knew that.” “And it points away from the body. Whoever made it stepped in her blood.” Across the aisle, a mirror reflected the victim’s grey coat and the bright legs of a tripod. Quinn followed the reflection up to its frame. Five tarnished mirrors hung there, but only four faced the same way. The fifth had its silvered back toward the aisle. “Your interpretation?” she asked. Voss shut his notebook. “Someone lured Farouk down here for a sale. It went bad. She fell, hit her head on the platform, and bled out. Seller panicked and ran.” “What was she buying?” “Pick a stall.” “And the cause of the fall?” “Argument. Push.” “There’s no scuffing under her heels.” “She could have stood still.” Quinn glanced at him. “You’ve never pushed anyone who wanted to stay on their feet?” Voss gave her a flat look. “Not on a report.” The woman’s coat showed no damage. One button at the waist hung by a thread, but the other buttons remained fastened. Quinn bent until her eyes were level with Farouk’s face. Blood had dried inside the woman’s left ear. There was no visible injury to her forehead or nose. “Has the pathologist been down?” “Dr Shah’s on her way.” “Good. I don’t want anyone moving the body yet.” Quinn swept her torch along the tiles. The blood pool ended against a line of pale dust. Beyond it, the floor stayed clean for eighteen inches, then another dark stain marked the base of the vial stall. Not blood. Water, perhaps, with a greasy sheen. She aimed the beam beneath the stall. A small brass compass lay against the wall, its lid open. Verdigris greened the hinge. Protective sigils crowded the face. “Did we bag that?” “Photographed. Scene team’s waiting on an explosives check before they handle the merchandise.” Quinn kept her hands clear. The needle trembled, swung left, and settled toward the platform wall. It moved again, though neither of them had touched the stall. “Faulty compass,” Voss offered. “It doesn’t point north.” “Neither does that sign.” He nodded toward an enamel arrow marked WAY OUT. It pointed straight into a tiled wall. Quinn stood. Six strips of cleaner grout framed the arrow, tracing a rectangle the width of a doorway. The surrounding tiles bore water stains. Inside the rectangle, the tiles looked fresh. “Is there a room behind that wall?” “According to the station plans, a cable shaft. Bricked up in the eighties.” “Get someone to check the other side.” “We can do that after the body.” “Now.” Voss looked past her at the compass. “You think someone went through a wall?” “I think the plans might be wrong.” A camera flashed near the booth. Quinn turned to see a crime scene officer collecting a row of small white objects from the floor with tweezers. Teeth. Each sat a hand’s breadth from the next, forming a line between the stalls and the exit. “Did you photograph them in place?” Quinn called. The officer held up the camera. “All eleven.” “Leave the rest.” “There are more?” Quinn pointed her torch beyond the cordon. Two pale glints marked the stairwell, one on each of the bottom steps. “At least two.” Voss walked over to inspect them. “A trail.” “Or a boundary.” Quinn looked back toward the victim. “Where does it start?” They followed the teeth past the ticket booth. Quinn kept to the edge of the aisle while Voss counted aloud. Eleven on the platform, two on the stairs, then none until the landing. There, three more teeth lay under a collapsed timetable. The line ended at a waist-high turnstile rusted into its open position. Beside the turnstile, someone had cut a narrow slot in the old wooden ticket counter. A card pinned above it read ONE BONE PER ENTRY. “The maintenance workers came down here?” Quinn asked. “Through a locked service door on the other side of the stairs.” “So whoever used this entrance paid.” “For what?” Quinn studied the wood around the slot. A varnished patch surrounded it, free of the dust that filmed the rest of the counter. Hundreds of scratches crossed the lower edge. People had pushed hard objects through, again and again. She shone her torch into the slot. Something pale had caught in a splinter near the back. “Can you get that photographed before they pull it?” Voss waved the scene photographer over. While they waited, Quinn examined the turnstile. A fleck of grey wool clung to the iron bar. Farouk’s coat was grey, but her sleeves showed no snags. Quinn held her light close. The wool had a blue thread twisted through it. “Another customer?” “Or our seller.” Voss glanced toward the body. “What made you look at the turnstile?” “Someone polished the counter. Nobody bothered with the rail.” Voss followed her gaze to the iron bar. A thin smear crossed the dust at shoulder height. It bore the ridged outline of a hand wrapped in fabric. The photographer took three pictures of the slot and stepped aside. Quinn pulled on fresh gloves and used tweezers to lift the fragment free. It was a sliver of carved bone, drilled at one end. A length of dark cord remained knotted through the hole. “Bag it,” she told the photographer. “Separate from the teeth.” Voss wrote down the position. “You think Farouk carried a ticket?” “I think somebody broke one here.” “You have a woman dead beside a stall full of bottled poison. Why spend time on the entrance?” “Because the poison’s still bottled.” They returned to the platform. At the body, Dr Shah had arrived with a medical examiner’s bag and a cup of coffee she set well outside the cordon. She knelt on the clean side of the blood. “Tell me you’ve saved me an easy one.” “Head wound,” Voss answered. “Possible fall.” Shah parted Farouk’s dark hair above the right ear. “She has a wound. I’ll give you that much.” “How many?” Quinn asked. “One I can see.” Shah angled her penlight. “Narrow. Deep. If she hit a tile edge, I’d expect more tearing.” “A tool?” “Ask me after the post-mortem.” Quinn watched Shah check the woman’s hands. The fingernails were clean. A faint green stain marked the skin of her right thumb and forefinger. “Copper?” Quinn asked. “Could be.” Shah lifted the hand under her light. “No skin under the nails. No obvious defensive injuries.” Voss crouched beside Quinn. “Seller strikes her from the side, then takes the weapon.” “Leaves the purse?” “Leaves in a hurry.” Farouk’s handbag rested half under her coat. The clasp was open. Inside sat a phone, a travel card, a folded paper receipt and a small packet of tissues. Quinn asked Shah to move the coat hem enough to expose the bag’s base. The leather beneath it had stayed dry. “Whoever put the bag there did it before she bled,” Quinn said. “She could have dropped it when she fell,” Voss replied. “Then why is the clasp open?” He looked at the bag. “She had it open already.” Quinn held her hand over the purse, judging its distance from the woman’s fingers. Too far for a dropped bag to have remained partly tucked beneath her back. She shifted to the other side of the body. The coat fabric rose in a shallow ridge beneath Farouk’s left shoulder. “Shah. Can you lift her shoulder a fraction?” Shah slid two gloved fingers under it. A brass object caught the light. “Don’t move it,” Quinn said. Shah eased her fingers back. Quinn leaned in. A round impression marked the woman’s coat, green at its edges. The brass compass beneath the stall sat two yards away. This object was smaller, flatter. “A coin?” Voss asked. Quinn studied the sliver visible under the coat. “A token, perhaps.” “The one from the slot?” “Not if the fragment came off somebody else’s.” Shah examined Farouk’s neck. Quinn stood to give her room and noticed the mirror opposite them had changed. The fifth one still faced backward, but its frame threw a narrow reflection from the polished metal at its edge. It showed the blood pool, the vial stall, and a patch of bare floor behind Quinn. In the reflection, a second shoe print darkened that patch. Quinn turned. The tile looked blank. “Voss. Come here.” He joined her at the mirror. “What?” “Look at the floor behind me. In the frame.” He leaned close enough that his breath clouded the glass. “Print.” “Look at the floor.” Voss turned from the mirror to the tiles. He crouched and swept his torch low across them. A shallow depression cut through the film of dust: the same diagonal sole, the same nick at the heel. No blood. Its toe pointed toward Farouk. “There’s your approach,” he said. “Perhaps. Why could we see it in the mirror and not from above?” “Angle.” Quinn shifted her torch until the depression emerged. A second print lay beside it, almost buried under a scatter of pale powder. Then a third. They led from the tiled wall to Farouk’s body. The bloodied print led away from it, back toward the wall. Voss marked their positions with numbered tents. “Seller came from behind that fake wall, killed her, then went back.” “Walk the distance.” He rose and followed the prints, stopping where the last toe met the blood. Quinn stayed by the body. The line brought him within arm’s reach of Farouk’s head. “Could you strike her from there?” “With something long enough.” “The wound is narrow. Shah found no tearing. Look at her head.” Farouk’s right ear faced the wall. The wound lay above it. Voss extended his hand as if he held a blade, then lowered it. “I’d have to reach across her.” “Unless she stood facing you.” “Then she turned as she fell.” Quinn looked at the blood again. Its thickest point lay beyond the back of Farouk’s head, close to the stall, and a fine spray marked the underside of a glass shelf. The pool told one story; the spray told another. “Shah, can you tell whether she died where she lies?” Shah peered under the shelf. “Not from here. What have you found?” “Blood above her, where the wound couldn’t have cast it if she was on the floor.” Shah shifted on her knees. “Show me.” Quinn pointed out the spray. Shah followed its direction with her penlight, then checked the hair at the back of Farouk’s head. “She was upright when that blood hit the shelf,” Shah said. “Someone lowered her or she collapsed beneath it. I’ll need photographs before I move her.” Voss glanced between the bloody print and the wall. “That still gives us a killer coming in and going out.” “Only one bloody print,” Quinn said. “If the killer walked from here to the wall, where are the others?” “He cleaned the soles.” “With what? The dust beyond the print hasn’t shifted.” Quinn crouched at the print once more. The pale crescent in its tread caught the light. She adjusted her torch, and tiny parallel grooves appeared across its surface. “Not grit.” She turned to the vial stall. Its nearest shelf held several empty recesses among the bottles, each lined with green felt. One recess was shaped like a shallow crescent. “Check the stock on that shelf.” Voss read the slate tag fixed beneath it. “BRASS WORKS. No prices.” The compass lay directly below. Its open lid had a curved bite missing from the rim. Quinn compared the break to the pale mark in the print. The shapes matched. “Someone stepped on the compass,” Voss said. “After it fell. The broken edge lodged in the tread.” “Then they left the print when they stepped in blood.” Quinn tracked the print’s toe. It pointed toward the wall, but its heel lay deeper in the blood than its toe. The dark liquid had pooled inside the heel cut; only a thin film coated the front. “They stepped backward,” she said. Voss joined her. “Toward the body?” “Toward the wall. They backed into the blood, lifted that foot, and set it down here. No second print because they never walked across the pool.” “Where did they go?” Quinn looked toward the cleaned rectangle in the tiled wall. The brass needle beneath the stall shivered and pointed at it again. “First find out what’s behind those tiles.”
