After the loss of Artemis, Kydd returns to England to give evidence at the court-martial of the surviving officer. His account could destroy a career, but the consequences also threaten his own position and leave him vulnerable to removal from the service he has chosen.
Kydd and Renzi are sent to the Caribbean, where colonial dockyards, disease and the fighting around Guadeloupe replace familiar British waters. Service in the cutter Seaflower tests Kydd through small-ship warfare and an exposed voyage in which survival depends on judgement rather than rank.
