Seymour's finger is always on the current socio-political pulse i News
[Charles] Cumming is perhaps matched only by Gerald Seymour now when it comes to recounting field operations Sunday Times
[Seymour] has lost none of his talent for thrilling plots and creating credible and sympathetic characters, nor his journalist's eye for modern espionage tradecraft and techniques Shots Magazine
