As a cynical divorce lawyer I just wonder whether Lady Mary would hop foot it up the aisle quite as quickly in 2015? I think not, firstly she would have had a period of" try before you buy" and openly cohabit with her beau. Secondly Lord Grantham would have been engaging the family lawyer to protect the Title and all that goes with it. A pre nuptial agreement would be negotiated long before a wedding date was set. There would have been a bidding war between Lady Edith's publication and Hello for the publishing rights, assuming Lady Edith lost she would then be subject to an injunction to ensure she did not divulge commercially valuable material. By now there would be media frenzy Carson would become the Max Clifford of Downton and the Dowager would be describing the whole thing as her annus horribilis.
