Determined not to be the scapegoat, and anxious to avoid possible criminal charges, Rainier sets out to prove the bank's responsibility for this and other shady transactions.

The Chevalier d'Aven gets five years in prison and the bank is exonerated in the eyes of the world, having apparently been the innocent victim of a cunning crook and an incompetent manager.

Since everyone agrees that Rainier could conduct a perfect business lunch, he ultimately ends up training young hopefuls in this subtle art.
