mother to please, please let us out. Maybe she hadn’t heard me or maybe she simply hadn’t cared. But now, with each clinging strand I brushed away, I imagined the web’s caretaker crawling on me, just as the spider in the closet had. I wanted to run from the forest, strip off my clothes, scrub myself with hot water and lye soap.

      Of course, I didn’t.

      I ignored the silly voice that gibbered fearfully at the back of my mind and concentrated on following Possum, guided mostly by the reflective strip on his collar. Periodically, I paused long enough to take a compass reading or tie a neon-yellow plastic ribbon around a branch or tree trunk at eye level. The markers would enable me to find my way out. Or help Chad and his people find their way in. Sometimes I spent a minute calling out to Tina and listening carefully, praying for a reply.

      She didn’t answer.

      When I wasn’t shouting Tina’s name, the only sounds besides my breathing and the crunch of my footsteps were Possum’s panting, the tinkle of the bell on his collar and his steady movement through the brush. Overhead, the canopy of trees thickened, almost blocking the sky. Night wrapped itself around us like an isolating cocoon, heightening awareness and honing instincts. Ahead, the inky blackness was broken only by the erratic flash of fireflies that exploded, rather than flickered, with brightness. Behind us, humans waiting beneath electric lights became distant and unreal, irrelevant to the search.

      Possum picked up the pace, moving steadily forward, detouring only for tree trunks and the thickest, most tangled patches of roses and raspberries. I struggled to keep up with him, knowing that calling him back or slowing him down risked breaking his concentration.

      I ignored the thorns I couldn’t avoid, dodged low-hanging branches, skirted tree trunks and stepped over deeper shadows that marked narrow streams, twisted roots and fallen trees. Sometimes I used my flashlight, running it over the ground to judge the terrain ahead. Always, I paid for that indulgence with several minutes of night blindness, and I didn’t turn the light on often.

      As I made my way through the forest, fragmented thoughts of Tina—fragmented bits of hope—floated to mind. Maybe we’ll find her easily. She’ll be tired and cranky and mosquito-bitten, but okay. She’ll be okay. Possum and I will take her back to her parents. To the parents who love her. Who would never harm her. She’ll be okay. We’ll find her, and we’ll go home. I’ll take a hot shower and have a cold beer. Possum can have a dog biscuit. Maybe two. If we find Tina. Alive.

      Ten minutes later, Possum’s pace slowed.

      He wavered, whined and stopped. He had lost the scent. A more experienced search dog, like Highball, would have known what to do next and done it. But Possum was still young and not always confident.

      I hurried to his side and gave him a brief, encouraging pat, then checked him for signs of heat stress. Youth had its advantages—he was doing fine. Then I pulled Tina’s socks from my pocket. When I held the bag open for Possum, he sniffed the fabric again, lifted his head, put his nose in the air, and wandered in an erratic little circle. He whined again, definitely frustrated.

      I oriented my body slightly to the left and pointed.

      “Go on,” I said. “Find Tina.”

      Possum followed my direction. I counted ten, slowly. When nothing about the dog’s movement hinted that he’d rediscovered Tina’s trail, I called him back. Then I turned to the right and sent him off that way.

      Still nothing.

      I moved forward several yards and we repeated the process. Left, then right. On each sweep, I sent Possum farther away from me. After that, he needed no direction and followed the ever-expanding pattern on his own. The night was still and humid—bad search conditions for any air-scenting dog. And although he was fit, Possum’s heavy coat made him susceptible to the heat. If he didn’t pick up the trail soon…

      Patience, I told myself. Patience.

      Minutes later, Possum rediscovered a wisp of Tina’s scent. His ears pricked, his tail wagged and his pace suddenly became faster and more deliberate. He continued through the woods with me at his heels.

      Between the darkness and the terrain, it was difficult to know how far we had gone. I knew where I was, generally. Knew that I could turn around and find my way back to the Fishers’ house. But, at the moment, the physical landmarks that were so clearly marked on Chad’s map had little to do with the reality of the forest.

      Possum’s collar disappeared. And didn’t reappear.

      I could still hear his bell, so I assumed he was simply blocked from my view. I hurried forward, not considering what I wasn’t hearing—the sounds of his movement through the brush.

      A spider’s web, strung between two trees at shoulder level, probably saved my life. I walked into it. And somehow noticed that, rather than trailing back over my neck and chin, the strands tickled my cheeks and nose, driven by the slightest stirring of upward-moving air. I stopped in my tracks, heart pounding from a sudden rush of adrenaline, my body sensing danger before my conscious mind registered it.

      I switched on my flashlight and, with hands trembling from reaction, aimed it two strides forward. And down. A long way down. Maybe forty or fifty feet. I’d nearly stepped off a soil-covered outcrop of crumbling limestone, nearly tumbled to the stream bed below. Now that I was standing still, I could hear moving water.

      The seeping groundwater that fed the stream had carved deep scars into the ravine’s limestone walls. Horizontal fissures marked places where softer rock had been washed away between layers of less porous stone. Soil had collected on the exposed ledges, creating islands of ferns and a network of slippery, narrow paths. In some places, water-weakened towers of limestone had sheered away from the walls, taking mature trees down with them. Everywhere, shattered trunks and branches were wedged across the ravine, creating a crisscross pattern of rotting and overgrown bridges.

      I told myself that Tina had not fallen into the ravine. I told myself that Chad was right—that my instincts were good—and that no human monster had abused and then discarded her over the edge.

      Possum’s bell jingled in the distance, and my flashlight beam made his collar glow. He had entered the ravine south of where I stood and was moving back in my direction, moving steadily along a ledge that would eventually put him six feet below me.

      Just a few steps away from me was a tree that leaned precariously over the ravine. An old cottonwood whose trunk was probably seven feet around. There was a ragged hole in the trunk, partially obscured by vines, that narrowed to a point at the height of an adult’s waist. The wider opening at the base was just large enough that it might look inviting to a child seeking shelter. I got down on all fours and bent my elbows to peer inside the dark scar, hoping to find Tina curled up asleep. Safe. And discovered that eroding soil, crumbling limestone and twisted roots had created a natural chute inside the rotting trunk. A chute that would send a body downward…

      I wrenched my light away from the interior, aimed it over the nearby precipice. A tapering curtain of long, thick tendrils hung directly beneath the old tree, the longest of them trailing down to the narrow ledge below.

      Impossible to see what those roots might be hiding.

      “Tina!” I called urgently.

      The slightest echo of my own voice answered me.

      She might be lying there unconscious. Or sleeping. She might not be there at all.

      The slope beside the tree was steep but not absolutely vertical.

      I checked the ledge carefully for signs of her as I considered my strategy. I could walk along the ravine’s edge until I found a place where I could climb down more easily. That would take time and I risked losing sight of Possum, but I’d probably not fall and break my bones. Or I could climb down right here, using the strongest of the tree roots to slow my descent.

      I put one hand on the cottonwood for balance and leaned way out into the darkness. Four feet below the first ledge was another jutting outcropping that was at least double the width of
