The novel is a dark comedy which follows the trip of protagonist Lewis Lambert Strether to Europe to bring the son of his widowed fiancée back to the family business.Henry James got the idea for The Ambassadors from his friend, novelist William Dean Howells, who while visiting his son in Paris was so impressed with European culture that wondered if life hadn't passed him by.The theme of liberation from a cramped, almost starved, emotional life into a more generous and gracious existence plays throughout The Ambassadors, yet it is noteworthy that James does not naïvely portray Paris as a faultless paradise for culturally stunted Americans. Strether learns about the reverse side of the European coin when he sees how desperately Marie fears losing Chad, after all she has done for him. As one critic proposed, Strether does not shed his American straitjacket only to be fitted with a more elegant European model, but instead learns to evaluate every situation on its merits, without prejudices, by selection. The final lesson of Strether's European experience is to distrust preconceived notions and perceptions from anyone, anywhere, but to rely upon his own observation and judgment.
