Steve Martin acts as a narrator to the story of Mirabelle Buttersfield (the Shopgirl), Ray Porter (an older rich businessman), and Jeremy Kraft (a young broke businessman) acting out a modern day love triangle. Mirabelle is more than a little off-kilter, but then so is the writing style on this short book (novella). It’s not so much a comedy of manners as a voyeuristic look at the three characters: how they see themselves and how they see each other. The funniest character is Lisa Cramer a co-worker at at Neiman Marcus in Beverly Hills. Lisa is a promiscuous, image-obsessed co-worker and voracious rival. Only Mirabelle doesn’t see her as rival. Lisa can’t stand the idea of Mirabelle having a ‘Sugar Daddy‘ and tries to steel Ray away with comic results.
