I did like it and, though it seemed quite obvious who the murderer was from an early stage (since that person talked to the police), I was still not so sure about the motives. I knew there was something wrong about the alleged poisoning of Carrie Louise, and I suspected there was no actual poison, yet I thought it was more about family secrets than money. On the other hand, I really enjoyed the process of thought that led *beep* and Miss Marple to the truth. It was interesting.
Another thing I really liked was Carie Louise and how her character was handled (everyone believed her oblivious but she ended up being the most sensible and perceptive). However, I didn't like the whole business with Gina and the boys, or how Gina's character was written.
