What does Lucy discover in the contract between Green and Martin, to suggest that Teddy is going to run away?

When Elvis goes to Mrs. Earle's house, he finds it ransacked and she is nowhere to be found. He calls a friend at the phone company and sees that she received a phone call from Terminal Island, the prison where her son is housed. According to his interview with Mrs. Earle at the start of the book, she does not talk to her son. In fact, they had not spoken since he was sent to prison six years ago. Elvis notices that LeCederick had called her, not the other way around, suggesting that he is behind his mother's change in her story. Elvis and Rossi then go to see Earle in prison.
