Unercover operative Sean Dillon returns and finds himself the target for a revenge-crazed killer, in a book which shows the kind of energy and invention that were the hallmarks of Higgins's early work. At the end of Edge of Danger the sinister Rashid family had been largely destroyed by Dillon and his crack undercover team. However, one scion of the utterly ruthless oil-magnate family was allowed to live - and that decision is one that Dillon comes to regret. The implacable Kate Rashid has seen her brothers being killed one by one, and has taken a vow of vengeance. But there are more lives at stake than Sean Dillon's: White House operative Blake Johnson and even the President himself are in the line of fire, and it takes all of Dillon's expertise simply to stay alive, let alone put paid to Kate Rashid's campaign. All of the set-pieces are delivered with authority, and Dillon is as economically - and persuasively - drawn as ever.
