There have been Grayles at Hartleap since Canute. They know this and are proud of the fact. Now they stand in a semi-circle round the bed of the very last of their nannies, who is quietly slipping away. Ada Stephens - known as Nanny Grayle, and well into her nineties - is saying farewell. Dirk’s sixth and final novel charts the demolition of a once proud house.
