I reached the Grices' house and pulled up across the street, taking a moment to study the house and yard. In the darkness, the fire damage was hidden, but the place still exuded that aura of ruin and abandonment. There was no sign of the car out front. No lights anywhere in the house. No pedestrians on the street.

I left the keys in the ignition and got out of the car, leaving the door ajar. I wanted to be able to ease back in and take off without a lot of fumbling around, if it came to that. I opened the trunk and took out the tools I thought I'd need. As soon as I determined that nobody was coming, I crossed the street and cut through the Grices' side yard.

I moved quietly along the walk, surveying windows as I passed. Most of the windows at the front of the house had been broken out by the fire and boarded back up again, but there were two near the back of the house that were still intact. I chose one and jimmied it open. It was pitch-black, and the neighborhood was quiet except for crickets chirring in the grass. I knew I should give myself an escape route, but I couldn't take the chance. If the two of them showed up, they'd spot any open windows or doors. I'd just have to work fast and hope my guess about the murder weapon was correct. I didn't have time for mistakes.

I climbed into the kitchen and pulled the window shut. The floor crackled with broken glass as I passed through. My flashlight streaked across blackened doorframes, smoke-tinged walls, into a hallway dense with shadow. I held my breath, listening. The silence was flat, one-dimensional. The electricity was turned off and I missed the soft hum of machinery. No refrigerator, no furnace, no wall clock, no water heater ticking from the other room. Some vague phrase about the silence of the tomb came to mind, but I pushed it away.

I moved forward, startled as a shard of glass popped underfoot. Was someone moving around upstairs? I swung the light across the ceiling, half expecting footsteps to appear up there like visible dents. The imagination has primitive, cartoonlike qualities, as any child can testify. I moved again. There was some illumination farther on, a pale light spilling in from the house next door. I paused at the window that looked directly into the living room across the way. Mr. Snyder was watching a television show, images flickering silently. The only other window on this side of the house was a small one just off the kitchen near the rear. I had a theory now about the banging May Snyder heard that night and I was about to test it out. I glanced toward the room where she slept, but it was already dark. I wondered if that's what old age is about-sleeping longer and longer hours until one day you simply don't bother to wake.

I ran my fingers along the window frame, shining the light across the fire-warped paint, a shriveled and puckered white, like dead skin. I could see where the wood had been damaged before. I could see where it had been secured with nails again: bang-bang-bang. I propped the flashlight on the window sill. It took me a few minutes to get the flashlight angled properly so I could see what I was doing and still have both hands free to work. I edged the narrow curve of the crowbar into the window frame and pried it loose with a crack so deafening it made my heart skip. I believed Elaine had been killed with a sash weight that had been tucked back in the window frame and nailed into place. The notion had come to me in one of those flashes of insight when I heard the weights in my own bathroom window thump dully against the studs.

It was nice. It had a certain domestic tidiness about it that Marty must have liked. If the house had burned down entirely that night, then who would ever have figured it out? The bulldozers would have mowed down what was left of the house, rubble loaded into high-siders, hauled off to the dump. Even now, even as it was, who was going to know? In a way, she was foolish to come back for it. Why not just leave it where it was? She was being pushed into a panic, probably anxious to tie up loose ends so that she could feel safe wherever she went. They might catch her, but what could they prove? The murder weapon probably had her prints all over it. Maybe it still bore strands of Elaine's hair or fragments of broken teeth and bones, microscopic particles of flesh. I wondered what she planned to do with the grisly thing. Bury it somewhere perhaps… toss it off the end of a pier. I jammed a big screwdriver into the tight crack between the framing and the strip of wood that held it in place. Window parts must have names, I thought, but I didn't know what they were. I was just imitating Becky's carpentry. The result was the same. I had the frame dismantled, exposing both sets of weights, the cord connecting them, and the pulleys that regulated the raising and lowering of the sash. I hauled both sets into view, four weights all together, careful not to touch anything. Shit, prints weren't going to show up on these things. The metal was covered with a thin film of sawdust and grime. Moisture in the wall had generated so much rust that any latent prints had probably been obliterated now. It wasn't going to help that six months had passed. Flecks of dried blood would still show up on a microscopic exam, but I wasn't sure what else. I shone the flashlight along the sash. At the tip were two glinting blond hairs caught in a knot of dark brown. I could feel my lips purse with distaste. I eased a small plastic Baggie over the tip and secured it with tape. I advanced the blade in the utility knife I'd brought with me and slashed through the cords, clanging the weights together inadvertently as I lowered them into a big plastic bag. Lieutenant Dolan and his trusty crime-scene crew would have fits if they saw me manhandling evidence this way, but I didn't have any choice. I tossed the utility knife in the plastic bag along with the rest of my tools, plastic rustling with my every move-which is why I didn't hear Leonard and Marty until they had already reached the back steps.
