The Man with no Borders by Richard C. Morais

A story of father-son-brother dynamics set in Franco-era Spain and later in exile in Switzerland. An aristocratic Spanish banker is nearing the end of a long and very successful life, but hallucinations carry him back to dark days of deeply hidden family secrets. His estranged sons return as he tries to put his house in order and exorcise his demons before it is too late. Cleverly crafted.
