Neighbor Liar Killer

I heard my sister being murdered over the phone. It was staged to look like a robbery gone wrong, but in her last moments, she was betrayed by someone she knew. Someone who had access to her home. Now her three girls are going to grow up without a mom, and I've lost the only person who's ever been there for me.And I'm going to find her killer. Someone in my sister's exclusive neighborhood killed her. The police are following their leads and I'm following mine. Unlike the detectives on her case, I don't have to follow the rules. And the closer I get to discovering who the killer is, the more the danger grows, for me and everyone around me. If I don't figure out who to trust, and fast, I'll end up just like my sister.
