George Marchs latest novel is a smash hit. None could be prouder than Mrs. March, his dutiful wife, who revels in his accolades and relishes the lifestyle and status his success brings.

A creature of routine and decorum, Mrs. March lives an exquisitely controlled existence on the Upper East Side. Every morning begins the same way, with a visit to her favourite patisserie to buy a loaf of olive bread, but her latest trip proves to be her last when she suffers an indignity from which she may never recover: an assumption by the shopkeeper that the protagonist in George Marchs new book a pathetic sex worker, more a figure of derision than desire is based on Mrs. March.

One casual remark robs Mrs. March not only of her beloved olive bread but of the belief that she knew everything about her husband and herself sending her on an increasingly paranoid journey, one that starts within the pages of a book but may very well uncover both a killer and the long-buried secrets of Mrs. Marchs past.

A razor-sharp exploration of the fragility of identity and the smothering weight of expectations, Mrs. March heralds the arrival of a wicked and wonderful new voice.
