Query: Disappointing

Generally, I like Forsyth's work a lot: The Day of the Jackal and The Odessa File are among the greatest thrillers of all time. But I'm afraid I didn't care much for this one. The story isn't very tightly plotted, and so with the lack of character development that has always been a weakness of Forsyth's, the narrative drags along intolerably at times. There is too much coincidence for the plot to be credible, and the wealth of technical details overwhelms rather the educates the reader. Even with all of these weaknesses, this novel is serviceable enough as beach or airplane reading. Still, The Afghan is disappointing when you realize what brilliant books Forsyth turned out in the past.
