Grant, the book "The Transformation of Mrs. McTwig" was not a real book. Its outlandish plot, however, was clearly inspired by a real book—Paul Gallico’s 1958 comic novel "Mrs. ‘Arris Goes to Paris," about a London cleaning lady who, after unexpectedly coming into money, travels to Paris to buy a Dior dress—and endures wacky adventures and romance along the way. Though I don’t think it’s while on safari with a Russian midget.
