Life aboard the Vanderley yacht is everything Bertie Wooster could hope for…right up until his pal Crumpet assaults a prince.

What follows is a swift descent into chaos: Bertie masquerading as a romance novelist, Crumpet posing as his own long-lost twin, and a sinister foreign count issuing a formal challenge to a duel. Meanwhile, Lady Stella has ideas about Bertie’s future that he finds deeply alarming. Will this madcap case of mistaken identities end in Bertie’s doom—or worse, his marriage? Have no fear; Jeeves will sort it all out.
