You are a lady's maid who can copy your mistress's hand and voice. She ran the night before her wedding, so you married the Earl of Wendmoor in her veil. He knew you at once, and he said nothing.
Where it begins
A rainy October morning in 1817, at the altar of Wendmoor chapel in Yorkshire. Cecily's hairpins scrape your scalp, and her new shoes pinch your feet.
You are Cecily's lady's maid. She ran away last night, so you stand at the altar in her veil, in her place.
The groom, Roland Cardew, Earl of Wendmoor, lifts the veil and breathes in once. He knows you are not his bride, and he says nothing.
In the front pew, Cecily's mother smooths her gloves. She hired you to stand in for Cecily, and you said yes: she clears your father's debts. Now the vicar asks if anyone knows a reason to stop the wedding.
