The van's rear doors stood cracked open, letting in a blade of cold air that cut across the back compartment. Maya sat cross-legged on the metal floor, the brass lighter balanced in her palm, her thumb moving in slow circles over the scratched numbers as if she could read them by touch alone. The streetlight outside flickered through the gap, casting a pulse of orange light that made the markings seem to move, to shift, to rearrange themselves into something else entirely.

Riley sat opposite her, back against the van's side panel, phone angled toward the lighter. The camera lens caught the scratches under its own tiny flash, and she squinted at the screen, zooming in until the image went pixelated and soft. She held it there a long moment, then exhaled through her nose and lowered the phone.

"Six digits," she said. "That's not random."

Maya turned the lighter over, feeling the cool press of brass against her fingers. "Could be a date. Month, day, year."

"Could be." Riley didn't sound convinced. She leaned forward, extending her hand. "Let me see it again."

Maya passed it over, and Riley caught it with the practiced ease of someone used to handling delicate things. She held it up to the gap in the doors, letting the streetlight hit it at different angles. The numbers caught the light and threw it back — tiny, deliberate marks that looked like they'd been made with the tip of a knife or the corner of a screwdriver. Someone had taken their time. Someone had wanted them to be found.

"If it's a date," Riley said slowly, "it's from eight years ago. The first two digits are eighteen."

Eighteen. Maya's stomach tightened. She'd been eleven then. Still in school. Still believing her father came home late because he was working, not because he was bleeding in some warehouse or trading secrets with men who wore scars like decorations. Eight years ago, Roman Cardenas had still been alive, still been building whatever empire he'd been building before Sorrento tore it down.

Before her mother had sold him for her safety.

"Or it's a combination," Riley continued, turning the lighter end over end. "Safe combo, lock combo. Six digits is standard for a lot of storage facilities."

"Storage facility." Maya heard the words land in the cold air between them. "Someone breaks into my apartment, moves my chair, opens my drawer, leaves a warm lighter on my father's ledger — and you're telling me it's a storage unit number."

"I'm telling you it could be." Riley met her eyes, and there was something steady in her gaze, something that didn't waver. She'd been scared when they found the lighter. She'd been scared when they found the chair turned. But now, in the back of her van with the door cracked and the cold seeping in, she looked like she was doing what she did best — making sense of things that didn't want to be understood.

Maya reached for the lighter, and Riley passed it back without hesitation. Her fingers closed around it, and she felt the warmth that still lingered from her own grip, the brass holding the heat of her palm like a memory. The numbers were visible even in the dim light, shallow grooves that caught the orange glow.

Eighteen. Forty-one. Seven.

Or one-eight-four-one-seven. Or one-eight-four-one-seven-zero. Six digits, arranged in a sequence that someone had chosen with care. She traced the first digit with her thumb, then the second, feeling the edges of each scratch, the slight burr where the metal had been pushed up by the pressure of whatever tool had made the mark.

"Southgate," Riley said quietly, and Maya looked up. Riley was staring at her phone again, her fingers moving across the screen in a pattern she'd memorized years ago. "There's a facility off the industrial belt. Southgate Self-Storage. It's where people keep things they don't want found during a police search but still want to find later."

"You know it."

"I've used it." Riley's voice was flat, careful. "Before I met you. When I was working alone."

Maya let that settle. She knew Riley had a past she didn't talk about, knew there were years the hacker had spent running her own jobs, burning her own bridges, building walls that Maya had only started to climb. She didn't ask. She never asked. That was the deal they'd made without ever saying it out loud — you don't ask about before, and I won't either.

But now Riley was offering something, a piece of that before, held out like a key.

"What's the system?" Maya asked.

Riley looked up from her phone, and the streetlight caught her glasses, turning them into two discs of orange light. "Four-digit facility code, then a hyphen, then a three-digit lockbox number. But some of the older facilities use a six-digit system — the first three are the facility, the last three are the box. No hyphen. Just the numbers."

"Eighteen-four-one," Maya said, trying the numbers in her mouth. "That's the facility?"

"Or the other way around. One-eighty-four for the facility, one-seven for the box. Or one-eighty-four for the facility, zero-one-seven. Depends how they coded it."

Maya turned the lighter over again, staring at the numbers as if they'd rearrange themselves into something clear. They didn't. They stayed where they were, small and deliberate and patient, waiting for her to make the next move.

The word fault line surfaced in her mind, left there by the anonymous texter who'd told her to find it after she found the mark. The fault line was where two things met — and broke. Where pressure built until something gave. Where the ground split open and revealed what was underneath.

"This isn't a clue," Maya said slowly, her voice barely above a whisper. "This is an invitation."

Riley was watching her, those hazel eyes visible now as the streetlight flickered again, the orange glow sliding across her face and then retreating, leaving her in shadow.

"Someone wants you at that facility," Riley said. It wasn't a question.

"Someone wanted me to find this." Maya held up the lighter. "They didn't hide it. They put it on top of the ledger, centered, aligned to the spine. They wanted me to pick it up. They wanted me to find the numbers."

"And the symbol."

Maya turned the lighter over, her thumb finding the curved-line-and-dot engraving on the side. The same symbol that had been pressed into the back cover of the ledger. The same symbol that had been carved into the stairwell wall at the textile mill. A signature. A calling card. A mark left by someone who wanted to be known without being caught.

She thought about the intruder standing in her apartment, lifting her chair, turning it to face the door. Opening her drawer just enough to signal that they'd been through it. Placing the lighter with surgical precision on the ledger's cover. A message delivered in objects, not words.

I was here. I touched your things. I could have done anything.

And instead, they'd left breadcrumbs.

"The numbers were scratched in," Maya said, more to herself than to Riley. "Not engraved professionally. Not stamped. Scratched. Like someone did it in a hurry, with whatever they had on hand."

Riley leaned forward, resting her elbows on her knees. "Or like someone didn't want it to be permanent. Didn't want it to look like it was supposed to be there."

The thought hit Maya sideways, and she felt it in her chest, a tightness that had nothing to do with the cold. "They didn't know if I'd find it. They left the lighter, and if I picked it up and looked close enough, I'd find the numbers. But if I didn't — if I was too scared or too careless — the numbers would stay hidden. Plausible deniability."

"Or a test." Riley's voice was soft, and there was something in it Maya hadn't heard before. Respect. Or recognition. "They wanted to see if you were paying attention."

The cold air crept through the van doors, carrying the distant hum of a truck somewhere on the industrial belt, the low thrum of the city moving in its sleep. Maya pulled her jacket tighter, the leather creaking as she shifted her weight, and she felt the photograph folded in her inside pocket, the one Dante had given her. Roman, her mother, Sorrento. Three faces frozen in a moment before everything had cracked open.

She pulled the photograph out, careful and slow, and laid it flat on the van floor between them. The streetlight caught the glossy surface, and the three figures seemed to emerge out of the dark — her father with his arm around her mother's shoulder, her mother pregnant and smiling, Sorrento standing to the side with that scar through his eyebrow and a smile that looked practiced and hollow and wrong.

"I keep thinking there's something in this picture I'm not seeing," Maya said. "Something about the way they're standing, or the way they're looking at each other, or —"

"The background." Riley shifted, pointing at a corner of the photo. "That building behind them. See the sign?"

Maya leaned closer, squinting, but the photograph was too small and too grainy. She shook her head.

Riley pulled out her phone, snapped a picture of the photograph, and zoomed in. The image went blurry, then sharpened as the camera adjusted. She held the screen up.

It was a sign. Part of a sign, really — the letters S-E-L-F visible on a white background, with the rest cut off by the edge of the frame. Below it, a number. One-eighty-four.

Maya's breath caught.

"That's the facility," Riley said. "Southgate Self-Storage, facility one-eighty-four. Your father had a unit there."

The impossible weight of it settled into Maya's bones, heavy and cold and undeniable. Her father had known. He'd known before he died. He'd left a trail — the ledger, the symbol, the lighter, the storage unit — and she was following it the way he'd wanted her to, the way he'd set it up for her to follow.

Unless someone else had set it up after he died.

Unless the intruder — the one who'd moved her chair and left the lighter — was someone who knew about the facility and wanted her to go there. Wanted her to find whatever Roman had left behind. Wanted her to walk into a trap with her eyes wide open.

"It's a gamble," Maya said, her voice steady even though her hands weren't. "Either this is my father's legacy, waiting for me to claim it, or it's Sorrento's people baiting a hook."

"Or it's the person who left the note in the stairwell."

Maya looked up, meeting Riley's eyes. The note that had told her to find the man with the spade tattoo. The note that had led her to Dante. The note that had set her on the path to the photograph, to the truth about her mother, to the lighter and the numbers and the facility that stood somewhere out in the dark, waiting.

"There's only one way to find out," Riley said quietly. "That's a storage unit number. Lockbox 417, at the Southgate facility. I know the system."

The words hung in the cold air between them, carrying the weight of a decision that had already been made, a threshold Maya was already stepping toward. The lighter cooled against her palm, the metal losing the last of her body heat, and she felt the truth of it settle into her chest like a second heartbeat.

The intruder hadn't just left a warning.

They'd left an invitation.

And Maya Cardenas had never been good at turning down a door that someone else had opened for her.
