Behind every great woman stands another one. And for television producer Tamsin, that’s Bea, her brilliant assistant. The only one Tamsin can trust with her coffee order, her dry-cleaning and filing; Bea does it all with a smile on her face. So when Tamsin hears a rumour that Patrick, her oldest and best friend’s husband, is cheating on his wife, she is furious. Knowing she can’t just ignore it, Tamsin plots a scheme to catch Patrick in the act, using Bea as live-bait. It should be foolproof. Except Tamsin never considered Bea might have her own agenda. And if she does, then Tamsin really needs to watch her back . . .
