Joanna Trollope has done it again! How exceptionally well she exposes the frailty of family life in Marrying the Mistress. I assumed I was just going to read about a married man and and his progressive relationship with his mistress, soon-to-be-wife; but not at all. We look very closely at the effect his actions have on the dynamics of his eldest son's marriage and family life, as well as the younger son's viewpoint. Then, of course, there's the grandchildren; one of them also going through the pangs of first love. The mistress, too, has all her own insecurities, not least her relationship with her mother. Much older man with young woman usually means the man needs to feel young again, but not Guy Stockdale; Merrion feels happier with an older man and theirs is a real 'marriage of minds'. The ending, though, is not what I was expecting! Once again, a fascinating observation of the complexities of the human mind - a story so well told.
