The biography traces the rise of a court favourite from modest provincial origins to central influence under two Stuart monarchs, charting personal ambition, patronage, and the social and political culture of early seventeenth-century England. Drawing extensively on State Papers and contemporary correspondence, it reconstructs his role in naval reform, diplomatic and military ventures—most notably the ill-fated expedition to La Rochelle—and the controversies that led to impeachment and violent death. The author balances documentary evidence with narrative of court life, explaining broader constitutional conflicts, summarizing key incidents, and appending primary materials to support an ostensibly impartial assessment.
