The girls didn't stay long. The last they'd seen of Katie she'd been throwing balls at some bowling pin targets, hoping to win a huge stuffed panda she'd liked the look of. It was almost as big as Katie, who was thirteen but looked eleven, tops.

Sue and the other girl had gone to a dark little tent to have their fortune told by Madame Rosa. When they came back to the ball-throwing attraction, Katie was gone. They looked around for her, couldn't find her, and decided she must have left without them. This was around six o'clock.

There was Cardinal's interview with the young man who operated the ball-throwing game. No, she didn't win the bear, and he hadn't noticed anyone with her, hadn't seen her leave. No one saw her leave. The ground, as Dyson said, had opened up.

Thousands of interviews, thousands of fliers later, Cardinal had learned nothing more about her disappearance. She had run away twice previously, to relatives in Mattawa. But her father's drunken rages had driven her to it, and when he was dead, her running stopped. Dyson had not wanted to hear it.

Cardinal got up and put a dressing gown on over his clothes, stirred the fire in the woodstove, and sat down again. It was only five, but it was already dark and he had to switch on the reading lamp. The metal chain was cold to the touch.

He opened the LaBelle file. William Alexander LaBelle: twelve years old, four foot-eight, eighty pounds- a very little kid. The address in Cedargrove was upper middle-class. Catholic background, parochial school. Parents and relatives ruled out as possible suspects. History of running, though only once in Billy's case. Never mind, it was enough for Dyson. "Look. Billy LaBelle is the third son in a family of high achievers. He's not doing as well as his football-star brothers, all right? He's not getting the grades of his high-wattage sisters. He's twelve and his self-esteem is in the basement. Billy LaBelle opted out, okay? The kid took a walk."

Where the boy had taken a walk to was a matter of less certainty. Billy had disappeared on October 14, one month after Katie Pine, plucked from the Algonquin Mall where he had been hanging out with friends. Sup reports included interviews with teachers and the three boys who had been with him at the mall. One minute he's playing Mortal Kombat in Radio Shack (sup reports of interviews with the salesman and cashier), the next minute he says he's going to catch the bus home. He's the only one of the four friends who lives in Cedargrove, so he leaves by himself. No one ever sees him again. Billy LaBelle, age twelve, steps out of the Algonquin Mall and into the case files.

Dyson had given Cardinal free rein for a few weeks after Billy's disappearance, and then the walls had closed in: no proof of murder, a history of running, other cases deserved priority. Cardinal resisted, certain that both kids had been killed, probably by the same person. Dyson on Billy LaBelle: "Christ, man. Look at his problems. He's got nothing going for him. My guess is he offed himself somewhere and he'll turn up in the spring floating in the French River."

But why were there no previous attempts? Why no obvious depression? Dyson had cupped his ear, feigning deafness.

Cardinal tossed the LaBelle file aside. He poured himself another cup of decaf and put another log into the woodstove. Sparks shot up like smithereens.

He opened the Fogle case, which contained little more than the top sheet- the facts from the initial report- courtesy of the Toronto police. I should have seen how things would go, Cardinal reflected, and perhaps he had. Dyson had been right: He had spent a lot of money, a lot of manpower. What else were you supposed to do when children vanished into thin air?

Margaret Fogle- at seventeen not really a child- had been the straw that broke Dyson's back. A seventeen-year-old runaway from Toronto? Not high priority, thank you very much. Last seen in Algonquin Bay by her aunt. McLeod's sup report with characteristic misspellings (where for were, "her parents where separated") was in the file. The girl's stated destination: Calgary, Alberta. "Which leaves half a continent and several hundred police forces responsible for finding her," Dyson had pointed out. "You hear me, Cardinal? You are not the country's sole policeman. Let the Horsemen earn their keep for a change."

All right, give him Margaret Fogle. With her out of the equation, it seemed even clearer there was a killer at work.

"Why do you keep saying that?" Dyson had fumed, not conversational anymore, not avuncular. "Molesters? Perverts? They go for boys, they go for girls, but they almost never- never- go for both."

"Laurence Knapschaefer went for both."

"Laurence Knapschaefer. I knew you'd say Laurence Knapschaefer. Too far out for me, Cardinal."

Laurence Knapschaefer had murdered five kids in Toronto ten years previously. Three boys, two girls. One girl got away, which was how they finally got him.

"The exception that proves the rule, that's what Laurence Knapschaefer is. There are no bodies, therefore this is not homicide. You don't have one scrap of evidence that it is."

"But even that could be taken as evidence for murder."

"What could?"

"The lack of evidence. It only bolsters my theory." He had seen in Dyson's cold blue gaze the doors slam shut, the bolts shoot home. But he couldn't leave it alone, couldn't shut up. "A runaway is seen- by bus passengers, ticket takers, hostel workers, drug dealers. A runaway is noticed. That's how we find them. A runaway leaves clues: a note, extra clothes or money missing, warnings to friends. But a murdered child- a murdered child leaves nothing: no warning, no note, nothing. Katie Pine and Billy LaBelle left nothing."

"Sorry, Cardinal. Your reasoning is out of Alice in Wonderland."

Next morning, Cardinal had ordered a grid search- his third in six weeks- that had come up empty. That afternoon, Dyson yanked him off Pine and LaBelle. Off homicide altogether for the foreseeable future. "Bring in Arthur Wood. He's robbing the citizenry blind."

"I don't believe this. Two missing children, and you're putting me on burglaries?"

"I can't afford you, Cardinal. This is not Toronto. If you miss the big time so much, why don't you go back there? In the meantime, you can bring me the head of Arthur Wood."

The Fogle file landed on top of the others.

Cardinal warmed up a tourtiиre he'd thawed out earlier. Catherine had wheedled the recipe out of a French-Canadian friend, but McLeod had tried it once and claimed they'd stolen it from his mother. It was the sage that gave them away.

He ate in front of the television, watching the news from Sudbury. The discovery of a body on Windigo Island was the lead. Grace Legault had pulled back her hood to do her stand-up on the island, snowflakes winking out like stars on the lion's mane of chestnut hair. She looked a lot taller on television.

"According to Ojibwa legend," she began, "the Windigo is the spirit of a hunter who went out in winter and got lost in the icy woods, where he was forced to live off human flesh. It's easy to believe such a legend when you set foot on this desolate island, where yesterday afternoon the body of an unidentified adolescent was discovered by a couple of snowmobilers."

Thanks, Grace, Cardinal said to himself. We'll be having the "Windigo killer" next, or even "The Windigo." Going to be a circus.

The report cut to file footage of the OPP dragging Lake Nipissing in the fall, while Legault speculated on whether the body might be that of Billy LaBelle or Katie Pine. Then they cut to Cardinal on the island acting cool and official, telling them let's wait and see. I'm a conceited prick, he thought. I see too many movies.

Cardinal wished he could phone Catherine, but she didn't always respond well to such calls, and she rarely called him from the hospital. I feel too embarrassed and ashamed, she told him, and it all but undid Cardinal to think that she could feel that way. Yet somewhere within that welter of feelings, he was aware of a lurking anger that she could abandon him like this. He knew it was not her fault, and he tried never to blame his wife, but Cardinal was not a natural loner, and there were times when he resented being left on his own for months at a time. Then he would blame himself for being selfish.
