Book review 1-13

I read this book "Love or Money?". I think it expresses the tenacity of purpose of human beings to money.
One day, Molly Clarkson and her husband hold a party and invite her relatives. However, they have designs on her money because she has lots money. Some of them hope her death. After that, Molly died in her bed. It's a murder case. A detective and inspector investigate people who were in the house last night. Who is the criminal person? I do not write the name on this post.
Human beings yield to temptation to get money and other advantage. In order to meet the aim, they plot many things. Human beings are wonderful creatures, but on the other hand, they are also very ugly. I think this story include human's mentality.
