Meet Mimi. Mimi may "have it all" - the house, the children, the part-time vanity job, the skinny jeans, the feng shui guru - but life chez Fleming is not as cushy as she'd like (husband Ralph prefers the trout stream to the fast lane). And when Mimi meets Si, the new billionaire on the block, she soon faces a choice of keeping up or keeping it real. Then there's her best friend Clare, neat-freak garden designer, deep in biopanic about her childlessness with eco-architect husband, Gideon. Clare monitors all illicit activity in the private West London compound, from light adultery to heavy building work, and she is watching Mimi.
