Query: Good beginning, atmospheric middle, dreadful last 50 pages.

It began well with interesting believable characters. It built tension throughout but the atmosphere was gone by the end. The plot petered out to nothing, no great drama in the conclusion just an anti-climactic squib where it was comfortably resolved with no great finale. If Barbara Erskine reads her reviews she should take note not to go on holiday towards the end of writing a book because that's how it felt to the reader. Where was Katherine's malevolence!!! one barely interesting paragraph?? You should have stuck with the mother Margaret, she was far more interesting and a better developed character to play the baddie.
