The rumors about the accident continued to whip through Glendale with the same hit-or-miss velocity of the breezes that cut through the courtyard at the high school. Everyone’s information seemed to be fourth-or fifth-hand; each new piece of gossip had the life span of a soap bubble. People did not seem to care if the boys had really done what they were suspected of doing. Their primary concern was whether it was fair to pursue such an inquiry in the wake of their deaths. People were people and pigs were pigs; their lives should not be equated in any way.

The gossip spun ’round and ’round like a child in a tantrum, reckless, indifferent to its own strength. The Snyders wanted an investigation. The Glendale families wanted the controversy buried with the boys. The matter was resolved in an unexpected way when an anonymous benefactor stepped in and made restitution to Cyrus Snyder. The police dropped the inquiry-after all, there was no one to charge, and the murder of a pig, unlike the murder of a person, was not a statistic that demanded a clearance. In the end no one in Glendale really knew if the boys’ clothes had been tested for the presence of nonhuman blood, as rumor had it. Or if a bag of poison had been recovered from the wreckage of the car. It probably wasn’t true either that Kenny Raskin, dying slowly behind the wheel of his overturned SUV, had attempted to make a full confession to the firefighters attempting to extract him. His injuries had been much too severe for him to speak.

Once everything settled down, Alexa Cunningham tried to use the tragedy as a learning exercise, explaining to her students that spreading such rumors was irresponsible and cruel, that people could even be sued for making false allegations about private citizens.

“In your history class,” she had told her girls, “you are taught the difference between primary and secondary sources. In the media there are distinctions among knowing something first-, second-, and thirdhand. Primary, or firsthand, refers to things you have observed. The moment you rely on someone else’s account of an event, no matter how authoritative, you open yourself up to errors. Even in retelling the details of an event that you have seen, you may make mistakes, large or small. Memory is imperfect.”

She told them about the fallibility of eyewitnesses in criminal cases, reading from a piece in the New Yorker. She put them through an exercise, asking half of the students to leave the room while the others watched Ms. Cunningham and the history teacher, Mr. Nathanson, act out a skit. The other students were then summoned back to the room and paired with those who had seen the skit. Based on the retelling, they had to write short reports about what happened.

“It’s like Telephone,” Ms. Cunningham had concluded after sharing some of the funnier errors with the students. “Only it’s not a harmless game. Misinformation can ruin a person’s life.”

A girl’s voice called from the back of the room, “But what if a story is true? Can someone sue you for telling the truth?”

A few girls gasped, but it was a fake shock, a form of mockery. The girl who had asked the question was Eve Muhly, and everyone knew that the stories about her were true. Who was she going to sue, when sixty other sophomores had seen exactly what she did?

“The point of this exercise is just how hard it is to know the truth of anything. If you don’t have firsthand information from primary sources, you shouldn’t gossip about it.”

“What if you talked to the victim?” Eve persisted. “Because I did.”

“I didn’t know,” Ms. Cunningham said, “that you were a pig whisperer, Eve.”

Everyone laughed, and Ms. Cunningham looked uncomfortable at the success of her joke, clearly aware that she had been less than teacherlike in her demeanor. But Eve didn’t seem to be the least bit perturbed.

“I mean the Snyder family. We live next to them. My dad went over there after he heard what happened. Would my dad count as a firsthand source?”

“No, he would be secondhand, unless he told you about something he observed directly, not what Mr. Snyder told him. But really, Eve, the point is not to talk anymore about this horrible incident, the point is-”

“My dad saw it. So it’s firsthand. He saw the letter with his own eyes.”

“Eve-”

“They used blood to write a note. It said, ‘We’re coming for your pig daughter this summer.’”

This gasp was real. This information was new, and quite provocative. Binnie Snyder was not as pink and red-eyed as she had been in grade school, but she was still an odd girl with carroty hair, a girl so advanced in mathematics that she took extra classes at Johns Hopkins. When she spoke in class-and she spoke often-her voice was too loud and strangely inflected. And she still had a way of squinching up her face when thinking hard. “Pig” would have been unkind, but not altogether untrue.

“I think,” Ms. Cunningham said, “that we’re getting off topic.”

Josie, who was there for the session, could not wait to tell Kat and Perri about this development. She raced to find them as soon as class was over, risking a tardy slip for English. She reasoned that it was okay to tell Kat about Eve’s information because she wasn’t saying it was Seth, Chip, and Kenny, whose guilt could not be established. The point was that the perpetrators, whoever they were, were so much more evil than anyone had realized.

But Kat had shook her head, refusing to believe the story even in its generalities.

“Eve Muhly is a slut,” she said, shocking Josie, who had never heard Kat speak so cruelly of anyone. “And a liar. Everyone knows that. She’s just making stuff up to get back at the people who talked about her.”

“Don’t use ‘slut’ just to criticize some girl you don’t like,” Perri said, her voice a dead-on imitation of Ms. Cunningham’s. She switched to her real voice. “Seriously, if anyone is a slut in this scenario, it’s Chip. He went after girls the same way he scored goals in soccer. But everyone thought he was cool, whereas Eve gets in trouble for giving one blow job.”

“He’s dead,” Kat protested.

“And when he was alive, he wasn’t very nice. People don’t become something other than what they were just because they had the misfortune to die.”

“Okay, Chip wasn’t the greatest guy. But Seth was our friend,” Kat said. “And everyone loved Kenny. We’ve known them both since we were five years old, Perri.”

That gap, seldom alluded to, always made Josie feel a twinge of jealousy and insignificance. She hated being reminded of Kat and Perri’s longer history, the three-year difference she could never make up. The three could be friends for eighty years, and yet Kat and Perri would then be friends for eighty-three.

“But what if they really did it?” Perri persisted. “How would you feel about them then?”

“I’m not going to speculate about someone who’s dead.”

“Why not?”

“It’s mean, it’s harmful.”

“To whom? They’re dead and it’s not like their parents are standing here.”

Josie had watched them, anxious, filled with regret that she had brought them what she considered nothing more than a juicy story, only to start this near fight. Ms. Cunningham was right about the destructive power of gossip.

Kat and Perri glared at each other. It all seemed so much angrier, so much more personal, than it had any right to be. But Kat had no talent for anger, and she broke first.

“I can’t be sure of anything. I don’t know, and you don’t know, and Eve Muhly definitely doesn’t know. She was, like, borderline retarded when we were kids, remember? I can’t believe you’re taking her side.”

“I’m not. I’m just being open-minded. There are infinite possibilities here.”

“If someone said anything horrible about you or Josie, accused you of doing something disgusting, wouldn’t you want me to defend you?”
