A claustrophobic story set around Jane and Graham Drummond; two of their friends, Tom and Ellie; Mr. and Mrs. McGregor, a couple who come to help while Jane takes a temporary job in London. And there are, of course, the children -- Jane's two and the McGregor child -- around whom explosive jealousy and hate swiftly begin to condense. During the long, wet summer, the failing architect and his career wife, the television personality, Jane's girlfriend and the baleful McGregors slowly build their relationship into... murder.
