A mysterious keepsake, a murdered bride, a legacy of secrets...

One balmy June evening in 1881, Phoebe Stanbury stands before the guests at her engagement party: this is her moment, when she will join the renowned Raycraft family and ascend to polite society.

As she takes her fiance's hand, a stranger brandishing a knife steps forward and ends the poor girl's life. Amid the tumult, he turns to her aristocratic groom and mouths: 'I promised I would save you.'

The following morning, just a few miles away, timid young legal clerk William Lamb meets a reclusive client, whom he was never meant to meet. He finds the old man terrified and in desperate need of aid: William must keep safe a small casket of yellowing papers, and deliver an enigmatic message: The Finder knows.

With its labyrinth of unfolding secrets, Claire Evans' riveting debut will be adored by fans of Kate Mosse, Carlos Ruiz Zafon and Jessie Burton.
