Grace Armstrong believes that she has come to terms with her own loss, the death of her dazzling fiance who was declared Missing in Action.

But soon he starts to reappear both in her waking life and dreams. To make matters worse, a body, dragged from the Thames, is identified as Elizabeth Smith, who lodged with Grace and her family for the last eight years before suddenly disappearing. Elizabeth had been more than a lodger; she had become a close friend to Grace, who feels compelled to uncover the true circumstances of her death.

In doing so, she is drawn reluctantly into the sordid and dangerous underbelly of London and a scandal that rocked Edwardian society.

Will Grace find the answers she so desperately craves, or will she lose herself in the search?
