Pattern is only thirteen, but is already rising through the ranks at Mrs Minchin's Academy of Domestic Servitude and seems destined for a life below stairs.

But fate intervenes when she is packed off to the small and secretive Duchy of Elffinberg, to serve as lady's maid to the lately orphaned Grand Duchess.

Pattern's young new mistress is excitable and paranoid, yet despite their differences the two girls forge an unlikely friendship that quickly turns into a battle for survival. For picture-perfect Elffinberg hides an extremely dark and deadly secret . . .

Armed only with her trusty sewing basket, a bottle of smelling salts and J. Bulcock's inestimable guide, The Duties of a Lady's Maid, Pattern will need all her wits and resourcefulness when dealing with above-stairs conspiracies and below-stairs intrigue. Darning stockings has never been so dangerous.
