There is a classic mystery in the murder case, but I did not like the characterization and motivations of the heroes, for example a rich girl who is bored, desires to solve a murder, gets involved in risky situations, another hero who decides to go alone at night to a house to see what will happen... and the names confuse you. I do not consider it one of Christie's best and it is the first book that I have not finished reading!

Very nice (like most of the author's works) but this one has more action... Also, it doesn't have a detective and that makes it even more mysterious and appealing. It has elements of mysticism/secret organizations and overall it is very adventurous and thrilling... I highly recommend it without hesitation!!!
