I sat straight up in bed, my breath coming hard, my hands shaking. I looked at my watch. It was two in the morning. I shook Dixie Lee awake on the couch.

"I've got to go east of the Divide. You have to take care of Alafair until I get back," I said.

"What?"

"You heard me. Can you do that? Fix breakfast for her, walk her to school, pick her up in the afternoon?"

"What's going on?" His face was puffy and full of sleep.

"I have to depend on you, Dixie. I'll be back by tomorrow evening. But you've got to take good care of her. Call in sick at work if you have to."

"All right," he said irritably.

"But what are you doing?"

"I think I'm going to nail Mapes. I think I'm going to do it."

He sat up on the edge of the couch in his underwear, his arms draped between his thighs. He widened his eyes and rubbed his face.

"I hate to tell you, son, you still act like a drunk man," he said.

Fifteen minutes later I stopped at an all-night diner on the edge of town, bought a thermos of black coffee, then I was roaring up the highway along the Blackfoot River, the tree-covered crests of the mountains silhouetted blackly against the starlight, the river and the cottonwoods and willows along the banks aglow with the rising moon.

It was dawn when I drove down the dirt road where Clayton Des-marteau had gone into the ditch. The hardpan fields were wet with dew, and the long rays of the sun struck against the thick green timber high up in the saddles of the mountains that formed the Divide. I took an army entrenching tool out of the back of my truck, jumped across the stream on the north side of the road, and walked up the incline into the lodgepole pine. It was cool and the wind was blowing, but I was sweating inside my shirt and my hand was tight on the wood shaft of the E-tool. Low pools of mist hung around the trees, and I saw a doe and her fawn eating in the bear grass. Then I intersected the thin trace of a road that had been used as an access to a garbage dump, and walked on farther across the pine needles until I hit the stream that flowed under a heavy canopy of trees at the foot of a rock-faced hill, and followed it across the soft moldy remains of a log cabin, a rusted-out wood stove half buried in the wet soil, and carpets of mushrooms whose stems cracked under my shoes. Finally I saw the spring that flowed out of the hillside, glistened on the dark rocks and moss, and spread into a fan of blackened leaves and rivulets of silt at the edge of the stream.

Annie and my father had tried to tell me in the dream, but I hadn't understood. It was winter when Vidrine and Mapes had murdered Clayton Desmarteau and his cousin. It was winter, and the ground must have been frozen so hard that a pest hole digger could only chip it. My heart was beating as I unscrewed the metal ring under the blade of the E-tool, folded the blade into a hoe, and tightened the ring. I scraped away the layers of leaves and raked back long divots of silt and fine gravel, creating half a wagon wheel that spread out from the stream's edge back to the spring's source. My pants were wet up to my knees, my shoes sloshing with water. Then I reset the blade and began digging out a level pit in five-inch scoops and setting the mud carefully in a pile on the bank. I worked a half hour, until my shirt was sweated through and my arms and face were streaked with mud. I had begun to think that maybe Dixie Lee was right; I was simply behaving as though I were on a dry drunk.

Then my shovel hit the toe of a work boot, and I worked the sand and mud off the edges, the congealed laces, back along the gray shank of shinbone that protruded from the rotted sock. I uncovered the other leg, then the folded knees and the collapsed, flattened thigh that was much too small now for the cloth that lay in strips around it. The second man was buried right next to the first, curled in an embryonic position, the small, sightless, tight gray ball of his face twisted up through the soil.

I stepped back from the pit into the middle of the stream, cleaned the shovel blade in the gravel, then knelt on the opposite bank and washed my arms and face in the water. But I was trembling all over and I couldn't stop sweating. I sat on the bank, with my knees pulled up in front of me, and tried to stop hyperventilating, to think in an orderly fashion about the rest of the morning. I hadn't hit the perfecta in the ninth race, but it was close, if I just didn't do anything wrong. Then, as I wiped the sweat out of my eyes with my thumb and looked across the stream at the glistening mound of mud and silt that I had dug from the bodies, at the nests of white worms trial I had lifted into the light, I saw a corroded green cartridge that had been ejected from an automatic. It had the same bottleneck shape as the 7.62-millimeter round fired by a Russian Tokarev.

I had to drive three miles down the dirt road before I found a pay phone outside of a closed filling station. It had started to rain over the mountains, but the sky in the east was still pink and blue, and the air smelled of pine and sage. When I got Dan Nygurski on the phone at' his office, I told him all of it, or I thought all of it, but my words came out in a rush, and my heart was still beating fast, and I felt as if I were standing at the finish line at the track, my fingers pinched tight on that perfecta ticket, trying in the last thunderous seconds of the race to will the right combination under the wire.

"Let your motor idle a little bit," he said.

"How'd you find them?"

"They were run off the road between the beer joint and Clayton Desmarteau's house. I think Mapes and Vidrine took them out of the truck at gunpoint and drove them into the woods. An old road leads off the main one and runs back to a garbage dump. They got out there and walked back to the stream. But the ground was probably covered with snow and frozen solid. I bet you could bust a pick on it in wintertime. Then they walked across a warm-water spring, where the ground stayed soft and wet year-round, and that's where they shot Desmarteau and his cousin."

"Tell me about the shell again."

"It came up in a shovelful of mud. I didn't even see it until I had stopped digging. It's bottlenecked, like a 7.62 round. Mapes has got a Tokarev. He had it in his hand at his girl's house down in the Bitterroot. I think he had it in Lafayette, too. He was trying to get to his open suitcase when I hit him with the chain. Look, it's enough for a search warrant. But it's got to be done right. You can bring the FBI in on it, let them coordinate it."

"Oh?"

"They can use kidnapping and interstate flight, or depriving a minority of his civil rights by taking his life. The locals might blow it. If Mapes gets a sniff of what's going on before they serve the warrant, he'll lose the Tokarev."

"I had to take a lot of heat because of that phone tap."

"I'm sorry."

"It hasn't quieted down yet."

"I was up against the wall. I don't know what else to tell you. You want me to hang up and call the sheriff's office?"

He waited a moment.

"No, don't do that," he said finally.

"I guess we've got a vested interest. This whole Indian thing started with Pugh, and Pugh's had a longtime involvement with Sally Dee. Give me the directions again."

I told him in detail once more. The shower had moved eastward across the fields, and rain was now clicking on the roof of the phone booth. An Indian boy on an old bicycle with fat tires rattled past me on the road, his face bent down against the rain.

"I'll call the FBI and the Teton sheriff's office," Nygurski said.

"Then I'll be out myself. I want a promise from you, though."

"What is it?"

"Other people take it from here on in. You're out of it. Absolutely."

"All right."

"I want your word. You don't go near Mapes."
