1876. Nineteen-year-old orphan Esperanza Gorst arrives at the great country house of Evenwood to be interviewed for the position of lady's-maid.

But Esperanza is no ordinary servant. She has been sent by her guardian, the mysterious Madame de l'Orme, to uncover the dark and dangerous secrets that her new mistress has sought to conceal, and to set right a past injustice in which Esperanzas own closest interests are bound up.

Gradually those secrets are revealed, and with them the truth of who Esperanza really is, enmeshing her in a complicated web of intrigue, deceit, and murder that culminates in betrayal by those she trusted most.

A sequel to the widely praised The Meaning of Night, The Glass of Time is a page-turning period mystery and a gripping novel about identity, obsession and secrets.
