 Calvert is a typical MacLean hero, world-weary and sometimes cynical, yet ultimately honorable, who must battle bureaucracy as well as the bad guys to solve the crime.Calvert's frantic search for the hijackers and for the hostages they hold takes him over the remote isles and sea lochs and forces him to make allies of some unlikely locals.As is usual with MacLean, the plot twists and turns, not all characters are as they seem to be at first introduction, and the double-crosses continue to the very last page.
