My breath caught in my throat.
The sun was low, throwing pink and yellow rays across a blue-green ocean. Below me, the coast met the sea like a crumbled linen tablecloth. I could see our tiny community on Morris, beyond that Fort Sumter and Sullivan's Island.
To my left, the town of Folly Beach looked like a string of Monopoly houses crawling the beach. Here and there, a window or porch light glowed yellow in the rosy dusk.
I glanced up over my shoulder. The lighthouse was topped by a giant metal birdcage rising into an iron dome. The space inside was vacant. Gulls watched from the ironwork, wary of my unwelcome presence.
I imagined the powerful beam that had once sliced the darkness, guiding sailors safely to Charleston Harbor. It must've been an awesome sight.
Hi and Ben emerged onto the walkway.
"Whoa." Ben gazed down at his runabout bobbing far below. His face lost its color.
"Shelton, check this out," Hi called.
"Thanks, but I'm not falling to my death today."
"Your loss."
I circled the tower, taking in the panorama. Trespassing or not, I could've stayed forever.
"We should go." Ben's forehead was damp. He avoided looking down. "There's nothing here, and another boat could cruise by any time."
"One more area to check," I said.
Ducking inside, I hustled up to the lens room. Smaller than the one below, this chamber had barely enough footage to turn around. The iron framework rose above me, glassless, open to the sky.
No furniture. No equipment. Dozens of angry gulls. I didn't linger.
"Time to give up?" Hi asked.
I nodded. We'd looked carefully. The tower was an empty shell. This trip was a failure.
With exaggerated groans, the boys began the long descent.
What a waste, I thought. We were no closer to solving Katherine's murder than when we started. The killers were still in the clear.
I paused, watching the tops of the boys' heads spiral down the stairs.
It was stupid to think we could make a difference. That a bunch of teenage brainiacs could outsmart a murderer. Our adversary had probably been laughing the whole time.
Score another win for bad guys everywhere.
My fists clenched as my frustration boiled like a kettle. I was angry enough to spit.
SNAP.
The bird stink almost knocked me off my feet. I couldn't think, couldn't breathe. Gagging, I held my breath, desperate for fresh air.
Without thinking, I scrambled back out onto the gallery, desperate to escape the noxious fumes.
Outside, I gulped oxygen in huge gasps. Too quickly. Spots danced before my eyes. My vision expanded, then retreated down a long, black tunnel.
Terrified of falling, I sat down on the balcony, hands clamped on the railing.
Deep breath. Two. Three. Four.
Slowly my mind unscrambled. My head cleared, and the darkness receded. I glanced out over the water.
"Wow."
The world lay before me in immaculate detail. I could see the smallest objects with laser precision. Particles of vapor making up clouds. Water droplets hanging above foam-topped waves. A worm wiggling in the mouth of a sparrow. My own bedroom window.
My gaze flew across the harbor to Charleston itself. Lights now twinkled everywhere. Soft yellow rectangles in the homes along the Battery. Neon orange and blue strips near the old market. A stoplight changing from yellow to red.
Through the acrid ammonia, my nostrils picked up millions of other scents. Salt. Algae. Rotting vegetation. Diesel fuel.
And something else. New. Familiar.
I raised my chin. Sniffed.
There. That direction. Trickling from the watch room.
I crawled to the opening, poked my head inside, and sniffed. The odor flickered in and out, barely perceptible beneath the cloying stench of refuse.
With a jolt, I recognized the newcomer. Something I'd smelled only once before.
Excited now, I drew air through my nostrils. The reek of bird poop watered my eyes. I wiped away tears, tracing, hunting, pinpointing.
The smell was coming from the floor beside the small balcony staircase. If I hadn't sat right where I was, I might never have noticed.
I scurried inside and began clawing away leaves and turds. Bird crud coated my fingers and jammed under my nails. I fought the urge to puke.
Six inches down, I uncovered a steel grate in the floor, clogged with years of debris.
A noise startled me.
My head whipped around.
"Tory, what are you doing?" Ben was panting and his face was red. "I had to climb all the way back up."
SNUP.
I blinked. Shook my head.
"Shoot. I lost my flare."
"You were flaring up here? Why?"
"It just happened. Help me lift this. I smelled something underneath."
Ben didn't argue. Together we pried the grate loose. Beneath was more garbage. I dug with my hands, sifted through God-knows-what.
My fingers closed on something solid. Heart pounding, I dragged the object into the light.
The remains of a knapsack. Faded green. Caked with years of salt and dried slime.
