A trip to the French Riviera sounds like just the ticket for Marjorie and Mrs Jameson. But from the moment they step aboard the famous Blue Train to the Mediterranean coast, it becomes clear that this won’t be an ordinary vacation.
They’ve been invited to stay at the palatial Villa Beau Rivage for a month in the sun, after a dismal summer in London. Surrounded by diamond merchants, film stars, artists and art dealers, Marjorie is swept off her feet by her first experience of the beauty and colour of the Côte d’Azur.
She faces a dilemma when one particular artist sets her heart racing – but soon they are both caught up in the aftermath of a tragic death at a glamorous party. Luckily Mrs Jameson is there to keep her mind on the case, as they investigate just how far some people will go for money.
