The third Adam Bolitho story follows directly from RELENTLESS PURSUIT. The setting is the West Indies, with the post-Napoleonic "revolution" against the ban on slavery. The navy is stretched to the limit, ships laid up, appointments for captains and senior officers hard to obtain. There's a lot of rivalry, as well as the discomfort of working with ships and sailors who have only recently been deadly enemies. Adam and the Unrivalled are in the thick of it.
