Ellie Haskell, the author's anxiety-ridden heroine (The Thin Woman, etc.)--mother of infant twins; wife of handsome restauranteur Ben--is but one of the off-the-wall characters living in the English village of Chittenden Fells. Ellie has joined something called Fully Female, along with her housecleaner Roxie. Its creams and potions, exercise and instruction are designed to revive faltering sexual relationships. Ellie's participation serves to heighten her usual tensions and, after a series of silly plot developments, leads her to attempt the capture of a murderer. Meanwhile, the author works tirelessly at making Ellie charmingly capricious, but what emerges is an amiable flake whose inner dialogue often reads like unfunny stand-up comedy shtick. Over-the-top whimsy--harmless, but no joy.
