Not every door should be opened . . .

Somewhere along the cobbled streets of Paris, an apartment lies thick with dust and secrets: full of priceless artworks hidden away for decades.

High-flying fine art agent Flora from London, more comfortable with the tension of a million-pound auction than a cosy candlelit dinner for two, is called in to assess these suddenly discovered treasures. As an expert in her field, she must trace the history of each painting and discover who has concealed them for so long.

Thrown in amongst the glamorous Vermeil family as they move between Paris and Antibes, Flora begins to discover that things aren't all that they seem, while back at home her own family is recoiling from a seismic shock. The terse and brooding Xavier Vermeil seems intent on forcing Flora out of his family's affairs - but just what is he hiding?
