It's the Fourth of July weekend at the prestigious West Heart country club. Gathered for cocktails on the first evening are just some of the guests: the club president, the treasurer and his pregnant wife, the snooping school boy, the bereaved father, the taciturn caretaker, the prospective member, the private detective. And there will also be a body. And a fiendish mystery to solve. But everything else is all to play for. And you are about to find out that you have a role to play in this mystery too.
