J. Fitzgerald Molloy says in the preface "I have endeavoured to present a picture of the domestic life of a king, whose name recalls pages of the brightest romance and strangest gallantry in our chronicles. To this I have added a study of London during his reign, taken as far as possible from rare, and invariably from authentic sources. It will readily be seen this work, embracing such subjects, could alone have resulted from careful study and untiring consultation of diaries, records, memoirs, letters, pamphlets, tracts, and papers left by contemporaries familiar with the court and capital. The accomplishment of such a task necessitated an expenditure of time, and devotion to labour, such as in these fretful and impatient days is seldom bestowed on work."
