he fourth novel in the charming and hugely popular Sunday Philosophy Club series Philosopher and amateur sleuth Isabel Dalhousie is about to find her Edinburgh home life profoundly altered by the birth of her baby. But this event is not universally welcomed: Cat, Isabel's niece, has her reasons for not feeling warmly disposed towards the new arrival.
Isabel is nevertheless, as her profession dictates, philosophical about such difficulties. But it is her professional curiosity that draws her into the investigation of a strange affair involving a painter who is there, and then not there, and then there again. Who painted what, and when? These are exactly the questions which Isabel Dalhousie excels at answering - sometimes.
