Loser takes all, de Graham Greene

 

Mr. Bertram and Cary are about to get married. An unambitious assistant accountant, Bertram's plans for marriage are not particularly exciting. One day, he comes to the attention of Dreuther, the powerful director of his company, who changes Bertram's plan for him: they are to wed and honeymoon in Monte Carlo. Dreuther will meet the couple in Monte Carlo and be their witness, on board his private yacht.
