Robert Merivel is a dissolute young medical student when an accident of fate leads him to the attention of King Charles II. Finding favour with the King, Merivel embarks on the time of his life, enthusiastically enjoying the luxury, women and wine of the vibrant royal court, until he is called upon to serve his monarch in an unusual role. However, when he fails at the one thing the King demands of him he is cast out from his new-found paradise.
Determined to be restored to the King’s favour, Merivel begins a journey to self-knowledge that takes him to the depths of seventeenth-century society.
