Because the killer has to come back. The killer has to talk, to tell this story until it’s used up. Other stories, they use you up. To the only audience a killer can risk having, his victim. Cassandra on her bed of moss. The microphone hanging above her, connected to a tape recorder and a transmitter broadcasting to a sheriff’s deputy perched on rocks across the canyon. Far enough away he can swat mosquitoes without giving himself away. The headphones over his ears. Sitting on the ground, crawling with ants. All the time, listening. In his earphones, birds sing. The wind blows. You’d be amazed how many of the killers come back to say good-bye. They’ve shared something, the killer and the victim, and the killer will come to sit at the grave and talk about old times. Everyone needs an audience.
