The Magician's Lie question

Spoiler alert -- I think she lied about everything. She was a street-smart illusionist, and she knew how to work the crowd. She built on the sheriff's sympathy and worked her way into him and out of her problems. I think she killed a man she was tired of, but made him seem "evil" so the sheriff would "ease" up on her. She used the sheriff's weaknesses and insecurities to her own ends. She lied, and it worked.

Renata SPOILER ALERT..........I think the lie was that the door of the train was actually never locked but she was too afraid to ever escape Ray. She admitted to Holt that the door was unlocked (she had already implied that she was always locked in) and instead of running she chose to hide behind the door to kill him. She said "My fear was all he needed to keep me there." When he caught her in the lie she said it was the only lie she had told all night. Although you could say her suspicion that Clyde was outside the door and that he might have killed Ray was also a lie in that she didn't confide that to the officer.? (less)

I agree in that the literal lie was that she said she was always locked in when in fact she never was. However I think it had a more meaningful lie in the sense that throughout the whole book she claimed to be and tried to be brave and courageous and had the readers thinking the same thing. But then she had trouble admitting that she finally couldn't be brave or courageous anymore because it came to protecting Clyde's life. The lie was kind of to holt, to her readers, and herself.
