Caprice And Rondo - Dorothy Dunnett - Bog

The merchant Niccolo, soldier, banker to Kings; shunned by all who know him after revelations of his murderous mischief-making. But his talents are too great to be squandered, and a subtle political dance ensues as rivals in Poland, Venice, and Persia bid for his services in trade and war and diplomacy. He will discover a new purpose in life.
