Quotes:
Det. Roberts: [Tommy Nelson is gone] How did he get out?
Lou Francis: Installments.
Det. Roberts: Installments?
Lou Francis: Yeah, he did a Gypsy Rose Lee, come here!
[they find Tommy's clothes lying about]
Lou Francis: That, that's all that's left of him.
Det. Roberts: Evidently Nelson changed clothes... what was he wearing when you last saw him?
Lou Francis: Air... nothing but air... and then he asked me how he looked.
Det. Roberts: Wearing air? What are you talking about?
Lou Francis: I went to shake his hand, his hand was gone, I looked up to speak to him, his head was gone. Then he took off his shirt, his body was gone, he took off his pants, his legs were gone! Then he spoke to me, I was gone.
