Sketch, Fiber and Seal

Sketch went first, and Sketch touched nothing.

Sketch's whole nature was to record the scene before anyone touches it — and so Sketch drew. Where every flattened plant lay. Which way each one fell. The scuff on the floor by the third pot. The open door and the closed window. The exact position of a single dropped glove. Sketch measured, and noted, and sketched it all, building a perfect frozen picture of the scene the way it was found — before the room could be changed by the very people who came to understand it.

"People think this part's boring," Sketch admitted, carefully noting an angle. "All this drawing while everyone's itching to grab clues. But listen — the moment we start moving things, this scene is gone. This drawing is the only version that will ever exist of how it truly was. If I rush it, we lose the truth before we even begin." Sketch finished the last measurement. "Now you can come collect. Now it's safe to touch. Because now it's remembered."

And now it was Fiber's turn, and Fiber worked on a principle so small and so certain it felt almost like magic: every contact leaves a trace.

Whoever had knocked those plants flat had touched this room — and Fiber knew, with quiet certainty, that they could not have touched it without leaving something behind, and without taking something away. A thread from a sleeve caught on a broken stem. A fleck of paint. A single hair. A smear of soil carried in and dropped that didn't match the greenhouse's own. These were the traces — tiny, easy to miss, impossible to fake — and Fiber gathered them, one by patient one, into tiny labeled bags.

"This is Locard's promise," Fiber murmured, lifting a blue thread with tweezers. "You cannot enter a place and leave it exactly as it was. You always leave a little of yourself, and you always take a little of it with you. So the person who did this left something here — and they don't even know it." Fiber sealed the tiny bag. "Test the trace, don't guess at the story. The thread doesn't lie. The soil doesn't lie. They just quietly tell us who was here."

But a trace is only worth something if you can trust where it's been every second since — and that was Seal's whole careful life.

The moment Fiber lifted anything, Seal was there with the logbook. Bag it. Label it. Log it. Every single piece of evidence got its own bag, its own label — blue thread, third stem, 4:15 — and then, most important of all, a written record of every hand it passed through from that moment on. Fiber to Seal. Seal to the box. The box to the desk. Every step, every hand, written down.

"Because here's the thing nobody likes to hear," Seal said, logging the thread. "A clue is only as trustworthy as its chain. If there's one moment — even one — where nobody can say where this thread was or whose hands it was in, then anyone can doubt it. Maybe it got swapped. Maybe it got dropped somewhere else. A broken chain can't be trusted, no matter how good the clue." Seal signed the line. "So I write down everything. Every hand. Unbroken. That's how the truth stays the truth all the way to the end."
