'Not just a book, but an experience - one in which twists and turns are both on the page and in the very act of reading itself. Two haunting narratives conspire to create a dark, menacing tale that spans half a century of secrets as they echo back and forth - all while the sand slowly drains away . . . This is a story about stories and their perspectives, the passage of time and the slow march of the inevitable. Vivid, resonant, melancholy and beautiful' Janice Hallett

1880s England. On the bleak island of Ray, off the Essex coast, an idealistic young doctor, Simeon Lee, is called from London to treat his cousin, Parson Oliver Hawes, who is dying. Parson Hawes, who lives in the only house on the island - Turnglass House - believes he is being poisoned. And he points the finger at his sister-in-law, Florence. Florence was declared insane after killing Oliver's brother in a jealous rage and is now kept in a glass-walled apartment in Oliver's library. And the secret to how she came to be there is found in Oliver's tete-beche journal, where one side tells a very different story from the other.
