Novel 11, Book 18

Bjorn Hansen, a respectable town treasurer, has just turned fifty and is horrified by the thought that chance has ruled his life. Eighteen years ago he left his wife and their two-year-old son for his mistress, who persuaded him to start afresh in a small, provincial town and to devote himself to an amateur theater.In time that relationship also faded, and after four years of living alone Bjorn contemplates an extraordinary course of action that will change his life forever.
He finds a fellow conspirator in Dr. Schiotz, who has a secret of his own and offers to help Bjorn carry his preposterous plan through to its logical conclusion. But the sudden reappearance of his son both fills Bjorn with new hope and complicates matters. The desire to gamble with his comfortable existence proves irresistible, however, taking him to Vilnius in Lithuania, where very soon he cannot tell whether he's tangled up in a game or reality.
