Charlie is taking the plunge to become a private investigator, and her first official case is a doozy. When three of Zoe’s coworkers are shot in a brazen mid-day attack, Charlie is initially content to let the police deal with it. But when it becomes obvious the detective in charge has the IQ of a box of crayons, she decides to step in to ensure the killer is found. What appears at first glance to be a random attack quickly becomes more than that, and before she knows it Charlie finds herself scouring the island for a murderer, with the help of Dot and Rosie, of course. In case hunting down a shooter wasn’t enough, Charlie quickly nets herself another customer in the form of her eight-year-old neighbor. And of course, Charlie isn’t expecting Jake to take the news of her new career very well. Luckily, Charlie isn’t especially worried about his opinion, especially when she has so much on her plate. Is Charlie about to make a splash in her new career, or will she quickly find herself drowning, instead?
