Not the most original of plots--an actor must impersonate a terrorist well enough to fool the rest of the gang--but Garve's gift for effortless, fat-free storytelling makes this straightforward adventure a thoroughgoing, if hardly memorable, pleasure. The wife of a millionaire M.P. is abducted by anarchists; she'll be tortured and killed unless their imprisoned confederate is released. Enter narrator Robert Farran, a slightly alcoholic, very bored, out-of-work London actor and mimic, who quietly offers to pose as the prisoner in the exchange--for a huge fee. The dubious government officials agree to a test demonstration, so Farran learns the prisoner's walk and voice, is fitted for wig and heard, has minor plastic surgery to alter the tilt of the eyes. The test is a triumph, and even though Farran discovers that the millionaire M.P. is really broke and there'll be no fee, he goes through with the fake exchange. But how soon can he escape; how many hours can he get away with this charade in too-tight shoes among his supposed comrades (including a longtime bedmate)? Mission: Impossible material, and, by Garve's own standards, perhaps a disappointment. But ever so classily, easily told.
