A Trace of Smoke

Detective Elara Vance stood at the edge of the charred ruins, her black boots crunching over shattered glass and soot. The warehouse, once abandoned, was now reduced to a smoldering skeleton of beams and ash. Firefighters were packing up, but she remained still, scanning the wreckage.

She wasn’t here for the fire. She was here for the body.

“Male, mid-thirties, tied to a chair before the blaze,” the fire chief had said. “Someone torched the place after he was already dead.”

A murder, masked as an accident—but sloppily.

Elara squatted beside a twisted piece of metal. Something faint lingered in the air, even through the acrid smoke: lavender. Not the scent you’d expect in a warehouse. And not from any man she'd known.

She scribbled in her notebook:
Lavender. Arson. Male victim. Bound. Pre-mortem bruising. No wallet.
Then she paused. There, half-buried in the ash—a cigarette butt. Not fully burned.

Carefully, she bagged it.

The lab confirmed the obvious: the cigarette had been smoked by someone wearing berry-flavored lipstick. Female DNA. No match in the system.

Elara revisited the scene. Nothing new, until she noticed a camera mounted on a building across the alley. It pointed straight at the side door of the warehouse.

She pulled the footage.

There she was—a tall woman in a black coat and sunglasses. She arrived at 11:52 p.m., walked in calmly. Fourteen minutes later, smoke began curling from the building. The woman never came out.

That is, until Elara froze the frame at 12:08 a.m. The same coat. The same sunglasses. But now, her hair was tucked under a hat, her lipstick wiped away. She turned her head slightly as she walked by the camera—revealing a scar above her eyebrow.

“Elara,” her partner, Detective Marquez, said the next morning, “the vic was James Rourke. Real estate agent. Recently under investigation for fraud.”

“Someone wanted him silenced,” she replied.

“And that woman? Any leads?”

Elara tapped the scar on her temple. “That’s the key.”

They combed through mugshots from old fraud cases, con artists, angry clients. Nothing.

Then Marquez found her.
Lena Vale. Convicted four years ago for grand larceny. Disappeared after parole. Known for disguises. Known for holding grudges.

Rourke had testified against her.

Elara knew where to look now.

They found Lena in a motel on the outskirts of town. She answered the door like she expected them.

“Detective Vance,” she said, smirking. “How long did it take you?”

“Long enough,” Elara replied. “You're under arrest for the murder of James Rourke.”

Lena didn’t flinch. “Didn’t kill him. Just watched him burn.”

“That’s murder.”

She shrugged. “He deserved it.”

Elara cuffed her, but the scent hit her again—lavender, faint and clinging. A trace of smoke in her hair.

At the station, Lena confessed. She’d tracked Rourke for weeks, watching him, waiting. She said he ruined dozens of lives, not just hers.

“I gave him a choice,” she said. “Confess on camera, or burn.”

He laughed. So she lit the fire.

Elara watched the footage Lena had recorded on her phone. Rourke was tied up, furious, panicked. He didn’t confess.

And then, flames.
The case closed, but something nagged at Elara.
That cigarette.
---
Days later, the DNA came back with a match—not to Lena, but to her younger sister, Ivy Vale, presumed dead five years ago in a boating accident.

But Ivy had never died.

Elara dug deeper.

Security footage from a gas station near the motel the day before the fire showed two women—one clearly Lena, the other nearly identical but scar-free. Ivy.

Elara confronted Lena again.

“Where’s your sister?”

Lena didn’t answer. She just smiled.

“She was the one who lit the match, wasn’t she?” Elara asked.

“I’m not saying a word.”

“You took the fall to protect her.”

Still silence.

Elara leaned in. “You’re clever. But Ivy’s out there. And she made one mistake.”

“What mistake?” Lena asked, unable to help herself.

Elara smiled faintly. “She left a trace. A trace of smoke.”

Conclusion: The Smoke Always Lingers

In the end, the case wasn’t as clean as it seemed. Lena was behind bars, but Ivy was still out there, a ghost behind the flames. And Elara knew she’d be watching.
Because murder, like smoke, never disappears. It drifts. It clings. And if you follow it carefully enough, even the faintest trail can lead you straight to the truth.
