Mrs. Henderson slowly swept the blonde strands behind Chloe’s ear.

The hospital smelled of ozone and antiseptic; the outside air smelled of impending rain.

Dr. Reed had given me two hours while they ran broad-spectrum toxicological panels on Chloe’s blood. I couldn't sit in that plastic chair and wait for Richard’s lawyers to serve me with papers. I had to find the source.

I drove like a madwoman back to Oak Creek Elementary. The parking lot was empty now; the final bell had rung at 3:15 PM, and the yellow school buses had already carried the children home to their safe, warm living rooms.

Only two cars remained parked in the staff lot: Principal Vance’s sleek black Audi and an aging Honda Civic that belonged to Nurse Henderson.

I didn’t use the front entrance. I knew Vance would have locked it. Instead, I walked around the perimeter toward the gymnasium and the path leading into the woods behind the athletic fields.

A chain-link fence separated the soccer field from the dense tree line of Blackwood Creek. But near the corner post, the heavy wire had been pulled up, tied to a wooden stake to create a wide gap.

Scattered on the mud on the other side of the fence were tiny footprints—sneakers, sizes 1 through 3. Second and third graders.

Beside the prints lay a discarded plastic specimen jar with a brightly colored label: *Oak Creek Science Dept – Aquatic Ecosystem Sampling Project.*

My stomach twisted into a hard knot.

They hadn't just walked near the creek; the teachers had brought the kids down to the water’s edge to scoop up samples.

I scrambled through the gap in the fence, sliding down the muddy embankment into the overgrown ravine. The air down here was heavy, sulfurous, smelling of rotten eggs and stagnant chemical sweetness. Blackwood Creek wasn't running clear; it was a sluggish, oily sludge of milky gray and rust-orange.

Just fifty yards upstream, half-hidden by overgrown weeds and brambles, a massive corrugated steel pipe emptied directly into the water. Painted on the rusted concrete collar was a fading yellow stencil: *CYTEC INDUSTRIAL CORP – DRAINAGE OUTFALL 04.*

I pulled out my phone and began snapping photos. The pipe. The oily scum. The children’s tiny footprints pressed deep into the contaminated mud right at the water’s edge.

Then, my flashlight beam hit something floating near the reeds.

A dead bullfrog.

I stepped closer, aiming my phone camera. The frog wasn't decomposed. Its belly was split open, and emerging from the flesh along its spine were dozens of thin, charcoal-black filaments—identical to the line on Chloe’s neck.

One of them twitched.

I scrambled backward, slipping in the mud, barely catching myself on a tree root. My heart was hammering like a trapped bird against my ribs.

“Mrs. Miller?”

A voice called out from the darkness above the embankment.

I froze, clicking off my flashlight.
