How does the author use foreshadowing in Papillon?

There are many aspects of foreshadowing in the novel. For example, when Papillion agrees to pay Jesus to help him escape, they do not shake hands. He notes that this is not a good beginning to their relationship and he is right. When he arrives at the convent, one of the sisters who accompanies him seems reluctant to wake the Mother Superior for permission for Papillion to stay the night. He says that he should have just taken that as his cue to leave the area, but that he does not and that this "fatal mistake" costs him seven years in jail. These instances of foreshadowing are possible because they are being written from a point in the future long after these events, meaning that Papillion has the ability to look back on the events with the full knowledge of what is to come. That he shares these with the reader often helps build suspense.
