Another bouncy, flibbertigibbet escapade for artist H.J. Mavity--now deepening the cleavage on bodice-ripper books for editor Lloyd Dobkin--and for her current live-in, ex-hubby, and commercial voice-over specialist Ben Spanner (Even the Butler Was Poor). When Lloyd, who was loathed by his wife, is run over by a man in a ski mask driving a silver Audi while H.J. looks on, she feels compelled to investigate and, with Ben at her side, uncovers a clue: a butterfly birthmark on the tush of a cutie whose picture was submitted for inclusion in one of Lloyd's skin publications. But who is she and where is she now? Could she possibly be the famous Timberlake baby, kidnapped oh so many years ago? Would she inherit zillions if still alive? There's another death, a few dumb moves from a love-crazed chauffeur, and innumerable chances for Ben to do voice impersonations and save H.J., thus freeing her to worry about really major crises--such as turning 32. Cute and good-natured. And if it's a little too short and silly to merit its price tag, at least it's over before it wears out its welcome.
