Marguerite has been locked in the attic of her family home, a disintegrating Chelsea house overlooking the stench of the Thames. For company she has: a sewing machine, a copy of Mrs Beeton's Book of Household Management and trays of congealing food carried up to her with little regularity. Marguerite has been confined by her mother, Cécile, who is concerned about her engagement to an older, near-penniless solicitor, Mr Lewis, and wishes to educate her daughter on 'proper' married conduct - lest she drag the family's good name into disrepute. But why is Marguerite pursuing the aged Mr Lewis in the first place? Why are her mother's visits seemingly becoming less frequent? And just how much time has passed since the lock closed on the attic's hatch?

Carrion Crow is a transportive and gloriously gothic commentary on the constraints of polite society - and the even greater danger of conformity - that unfurls one family's festering secrets.
