"The Saint Zita Society’ is Ruth Rendell hitting the bulls-eye"
The Saint Zita Society convene in the Dugong at the end of Hexam Place. It consists of the folk who live and work for those privileged enough to own a place in Hexam Place, Pimlico. Saint Zita was the patron saint of domestic servants and their meetings allow them to voice their concerns for the local area and their disapproval of the way they are treated by their employers. They wish to make changes that will allow them more privileges and to stop people taking advantage of them: but the residents of Hexam Place, above and below stairs have their secrets and soon both worlds will collide when murder and subterfuge touches them all.
One such Saint Zita member, Dex works as a gardener for the kindly Dr. Jefferson and receives messages from his 'God' – his mobile phone service provider, 'Peach'. It is when Dex begins to receive calls from 'Peach' instructing him to rid the world of certain evil spirits that Hexam Place becomes the centre of destructive forces hidden behind the respectable facades.
