A deadly idea

For her upcoming exhibition, "Apology," Lily, a New York conceptual artist, is designing a sound and sculpture installation inspired by the testimony of anonymous phone callers who, after responding to a public advert inviting them to spill their guts, leave messages on her answering machine. When one caller confesses to a murder, Lily begins to suspect that the mystery man may be intending a little "performance" of his own: her death.
