Morath is in fact an amateur spy, sent on one dangerous mission after another at his uncle's behest (laundering money through the Antwerp diamond industry, or spending a week in a Romanian jail, for example).
Morath journeys across the continent by train frequently and sees a world of suspicious border guards, desperate passengers with the wrong papers, and tenuous luxury surrounded by encroaching violence and squalor.
But he and his uncle have a special cross of their own to bear, for they are among the scattered survivors of the old European upper class that failed to prevent the earlier war.
Morath lives for many years in a twilight world of secrets and danger, and seems to take solace in a series of easy women who ask no questions about the things that matter to him.
By forging a relationship with someone who demands to know what is truly important to him (Mary Day), he finds his soul mate even as their physical world crumbles around them.
