Former intelligence operative Tom Bullen finds himself lured into an intricate international web of death and deceit in this swiftly moving thriller. The pot of gold at the end of the bloody rainbow? The sale of three Russian nuclear bombs to Middle East terrorists. Curtis (Point of Impact, 1991, etc.) doesn't reveal the nature of the crime until well into the story, reeling in the reader, and Bullen, with a series of bloody assassinations carried out by two of the weirdest killers in current fiction. Bullen, an expert spelunker, is a man haunted by the vicious treatment he endured as a child and by his family's sordid history (both his mother and her brother are hateful neo-Nazis). He is manipulated into making an investigation after his uncle is gunned down at a funeral in France, one of the victims of the seemingly pointless murders. Sonia Bishop, who was an eyewitness to a similar massacre at a wedding in the United States, provides a vital key to unraveling the mystery. Bullen, drawn to her, at the same time wrestles with his conflicting feelings for the journalist who loves him and is risking her life covering the conflict in Sarajevo. When the trail leads finally to an international arms dealer in New Orleans and, through him, to a former KGB officer in Moscow, some unexpected additional treachery on both sides is revealed. For a relatively amateur spy, Bullen is perhaps too adept to be believable, but Curtis keeps things rolling along at such a rapid pace that many readers may not notice--though no amount of fast footwork can disguise the fact that the ending is disappointingly anticlimactic. The nuclear threat posed by postCold War anarchy in Russia warrants more serious treatment, even from thriller writers.
