Building on his haunting, superbly written debut, The Meaning of Night, Michael Cox returns to a story of murder, love, and revenge in Victorian England.

In the autumn of 1876, nineteen-year-old orphan Esperanza Gorst arrives at the great country house of Evenwood in Northamptonshire. There she will serve as the new lady's maid to the former Emily Carteret, now Lady Tansor. But Esperanza is no ordinary servant. She has been sent by her guardian, the mysterious Madame de l'Orme, to uncover the secrets that her new mistress has sought to conceal - and to set right a past injustice in which her own life is intertwined.

Unable to escape the reverberations of past misdeeds, Lady Tansor finds herself desperate to keep Esperanza from learning dark, dangerous truths.

As well as a page-turning period mystery, The Glass of Time is a beautifully written and vividly imagined study of seduction, betrayal, and friendship between two powerful women bound together by the past.
