So far what I think.......

Title: The Pact
Author: Jennifer Sturman

I have read and finished this novel called The Pact by Jennifer Sturman. The Pact falls into the mystery genre. So far my impression of this book is even the least likely person can be guilty.
For example throughout the novel I found that everyone had a possible motive to Richard. Richard was Emma's soon to be husband who no one liked. He wasn't a very nice person plus he didn't treat Emma very nice either. For the most part everyone had a good reason to get rid of him.
Matthew who is Emma's best friend and her mothers godson is a nice young man and is very much like the brother to Emma and all her friends, Matthew is also in love with Emma and he doesn't want him to marry Richard because he believed that Emma deserved someone better. Rachel who is also Emma's best friends one of the only female, investment banker in her company. When it comes to business Rachel doesn't like Richard because he stiffed her in a deal, but in the personal term Rachel doesn't like him because his disrespect toward her friend. When it comes to Emma's other friends Hilary and Luisa they have much more deeper reasons than others. Hilary dated Richard shortly after college and he dumped her which didn't sit in well with her. Luisa met Richard in college and he was really into her just as a lot of other guys were but, Richard put her in a different situation when he got her drunk one night and slipped something into her drink and raped her. Jane Emma other friend just don't like him because of the mistreatment of her friend. Lily Emma's mother seems to like him or does she really. Jacob Emma father really doesn't like Richard because he's just not enough for his only daughter and child. Peter, Richards only friend is just surprised that Richard even asked him to be his best man in the first place, because they haven't talked to each other in years. Plus Peter and Rachel seem to be attracted to each other.
Although Richard was found floating in the pool police believe that he may not have drown but my have been drugged by someone in the house. It's hard to solve this case because everyone has a reason to want him to be gone, not including Peter. Based on what you have read do you think that you would want him gone also?
