It's here at Total Sci-Fi, and the reviewer, Paul Simpson, absolutely gets it. "What starts off as a simple missing persons enquiry develops into a full-blown coup against a fascist state..." is a pretty good precis of the book.
He describes the setting as dystopian, one that "unlike many... seems all too plausible" but where people just get on with their lives. Absolutely! And he mentions "action sequences highly reminiscent of Adam Hall's Quiller spy novels." For me, there is no finer praise.
