Tamsin and Michelle have been inseparable since childhood. Even now they spend all their time together, along with Patrick, Michelle's handsome husband. Except Tamsin's brilliant assistant Bea (without whom Tamsin's life would fall apart) has heard a nasty rumour that Patrick is playing away. Determined to uncover the truth, Tamsin devises a honey-trap to test his resolve, using Bea as bait. But she never counted on Bea having her own agenda . . . Struggling to untangle the web of deceit, Patrick seems to be constantly one step ahead. Can Tamsin reveal the truth to Michelle without ruining everyone's life along the way?
