Confusion reigns when John Raven, London's ex-Detective- Inspector, now a private investigator, gets involved in a high- stakes undercover scheme to buy coded computer discs from the files of the old Communist government in Czechoslovakia. It's there that Catriona Dunbar, daughter of a Canadian envoy working in Prague, knows that her father is on the verge of making a fortune. When he dies of a heart attack, her slippery boyfriend Henry Gratton flies to Prague and attempts to take over Dunbar's scheme. He winds up murdered, and Catriona asks Raven to try to find out what happened. Meanwhile, others are watching the murky proceedings--Britain's M15; megarich business man George Brewster; menacing go-between Rotbart; and professorial Teodor Brodsky in Prague. They all talk in timeworn spy-story clichÇs, adding no sparkle to the flat chronicle of Raven's domestic routines and pedestrian conversations with airhead wife Kirstie. Muddled, dull, and inconsequential. MacKenzie (By Any Illegal Means, 1990, etc. etc.) has done much better.
