I have been a Christie fan for 35 years, and I agree with the previous reviewer. To my mind this is one of the best books she ever wrote. Perhaps because it does not feature Poirot or Marple it never really seems to get the attention it deserves. Christie is often criticised for being Plot Plot Plot and precious little atmosphere. It is suggested that creating a convincing atmosphere is beyond her. Well this is the book which disproves that theory. You could cut the atmosphere in this one with a knife. From the word go a strange, menacing, almost dreamlike aura hangs over this book. It is, apart from a (very) tangenital similarity to 'Murder Is Easy' in terms of motivation, quite unlike anything else she wrote. It seems to be one of those Christies that readers come to half-heartedly once they have exhausted the Poirots and Marples but I would place it pretty high on her list of classic titles, in fact I am not sure that I wouldn't place it at number one!
