I was expecting At Bertram's Hotel to be a little tedious like Nemesis but I was completely wrong. Although the murder doesn't happen until 3/4 of the way into the book there are 4 different mysteries going on at the same time which seem to be unrelated but in a fantastic finale we realise they are all connected. As always the murderer was totally unexpected. The book is set in an old-fashioned, expensive hotel in London so the setting is a nice change from the usual countryside. The characters are well-developed and the plot is great. The structure of the story is different to the usual Agatha Christie mystery which makes it more interesting. Although this is one of her longer books I found it so exciting that I read it in two days! I would say this is my third favourite Miss Marple book after They Do It With Mirrors and A Murder is Announced. Highly recommended!
