This book was an excellent read! The cover is beautiful, and just makes you want to crack it open, start reading, and never put it down again! The plot is what will really draws you in. It’s the end of senior year and this group of friends wants to have one last night of fun before they all go their separate ways. So why not do that in a mysterious mansion located on its own private island, complete with Rolls-Royces and jewlery/costumes from the roaring 1920s. The friends even leave their technology at home for the fullest experience. Suddenly a murder occurs! (Hence where this great title comes from). Anyone could have done it- at least they all have a motive. Two detectives are brought in to question the young adults and figure out who the killer is and why they murdered one of their friends. I recommend this book to anyone who enjoys a cozy Agatha Christie style mystery!
