On the eve of Elaine Southey's 21st birthday, Ivan Sweet has been found dead in his flat in the basement of the Southeys' historic north London home. A slick charmer to some of the tenants and a loathsome young scoundrel to others his death doesn't draw out many tears among the house's residents and neighbours. And yet the sordid truth starts to seep into the heart of their small community a murder is living among them, and who's to say when they might strike again? The shrewd Oxford man Superintendent Paul Grainger finds himself faced with a small circle of suspects whose connections and hidden motives heap complexity upon complexity in this tightly wrought mystery, shot through with a chilling touch of the macabre.
