I am a HUGE Agatha Christie fan, and of all the various fictitious detectives and sleuths she has created, Miss Marple is by far my favourite, due to her witty and hilarious character. At times, she is better in the books than she is in the television adaptations.
This first omnibus edition is one of three volumes; each individual volume collects four of the twelve Miss Marple novels. While these first four are all brilliant (and, as I have said, better than on either film or television), the only issue I have with this series is that the novels are NOT published chronologically: the first Miss Marple novel is the LAST one in the third volume, while the last one, also found in the third volume, comes in second. Personally, I feel that all the novels should have been published due to their publication dates. It is this problem that costs the series its five-star rating.
For me, the best novel in the first omnibus was A Murder is Announced: with suspense, various twists and turns, and a shocking yet surprising end, it stands out as one of Christie's best novels on the whole.
Though not worthy of five stars, there is one thing about the omnibus series that I love: it sure saves one money and space on the bookshelf than buying each novel separately. Worth it!
