Leaving Time discussion

“A second dispatcher walks toward me. She is a squat older woman, shaped like an apple, with a frizzy blond perm. She has a name tag, Polly. “Can I help you?”
“Yes,” I say, offering my most mature smile, because really, what adult is going to take a thirteen-year-old girl seriously when she says she wants to report a disappearance that happened a decade ago? “I’d like to talk to a detective.”
“What’s this about?”
“It’s kind of complicated,” I say. “Ten years ago an employee was killed at the old elephant sanctuary, and Virgil Stanhope was investigating it…and I…I really need to talk to him directly.”
Polly purses her lips. “What’s your name, sweetheart?”
“Jenna. Jenna Metcalf.”
Polly reappears on my side of the glass wall, entering through a doorway that has a push-button combination lock on its knob. She leads me to a bank of chairs and sits me down. “I remember that case,” she says to me.
“So you know Detective Stanhope? I realize he’s not working here anymore, but I thought you might be able to tell me where he is now…”
“I’m not sure how you’re going to get in touch with him.” Polly puts her hand gently on my arm. “Virgil Stanhope is dead.”

Was Polly also dead, or was she psychic?
