The Clockwork Sparrow meets Downton Abbey

It's a bitterly cold winter in Yorke and Rose Raventhorpe and her butler Heddsworth are stuck with Rose's unpleasant cousin Herbert, and his equally horrible butler, Bixby.

When an orphan boy named Orpheus interrupts the Cathedral's Mistletoe Service, saying that his sister has been kidnapped, Rose vows to help. Solving the mystery will be a lot better than accompanying ghastly Herbert! But the investigation is more complicated than Rose has anticipated and will lead her and her butler friends through fancy tea-rooms, horrible factories, secret underground passages and more...

Fireplace pokers are much more dangerous than you might imagine . . .
