The Turnglass

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 tête-bêche journal, where one side tells a very different story from the other.
