Why Bristol? Murder At BMS

In this. the fourth Natasha McMorales mystery, PI Nattie Morland is hired by Bristol Motor Speedway to solve a series of murders. When a vendor was found dead the morning after the August race they hoped it was just a random act, but when a second vendor meets the same fate after the March race that hope evaporates. Both victims are part of a group called the "Dog Pack" and they were both "killed bad".
Solving this mystery proves difficult as not all the members of the Dog Pack welcome Nattie's involvement. Everyone, it seems, has something to hide, and no one knows why it is happening in Bristol.
