Janet Byfield has everything Wendy Appleyard lacks: she's beautiful; she has a handsome husband, a clergyman on the verge of promotion; and most of all she has an adorable little daughter, Rosie. So when Wendy's life falls apart, it's to her oldest friend, Janet, that she turns.
At first it seems to Wendy as though nothing can touch the Byfields' perfect existence in 1950s Cathedral Close, Rosington,, but old sins gradually come back to haunt the present, and new sins are bred in their place. The shadow of death seeps through the Close, and only Wendy, the outsider, is able to glimpse the truth. But can she grasp its dark and twisted logic in time to prevent a tragedy whose roots lie buried deep in the past?
