[Not a Penny More, Not a Penny Less] has about as much substance as a soap bubble, but it is quite entertaining. It has to do with the efforts of four men—a professor, a doctor, an art gallery owner, and an English Lord—to retrieve from a slippery con man, who has all the charm of a pailful of hissing snakes, the million dollars they invested in his nonexistent oil company in the North Sea…. The book forces us to accept the most outrageous unlikelihoods of plot, but, by the same token, it doesn't put us under the slightest cerebral strain.
