What happens to the suitcase in Chapter 2? How would you explain the motivation for this action?

Bolt carries with him 50 million Swedish dollars in a suitcase. In an act of recklessness which the author describes as saying "yes" to life, Allan impulsively steals the suitcase, even though Allan doesn't have a clue what it contains when he does so. Allan is a man for whom all of life's meaning has been lost to time, and is the person least likely (or so it would seem) to commit such a crime.
