Some throwbacks are best forgotten.

With crime in Central Shores, Delaware, finally trending downward, social media influencer Coco Cline considers archiving her amateur sleuthing exploits. But when a blast from her friend Charlotte's past dies under suspicious circumstances, all thoughts of Coco leaving her crime-solving days behind get deleted. The local police are looking at Charlotte, which means Coco needs to find them another suspect, or even better, the real killer.

Teaming up with the Sleuth Squad to clear one of their own, Coco and her friends scour the victim's socials for clues. What was this guy doing in Central Shores? Who did he have ties with other than Charlotte?

With the evidence mounting against Central Shores's favorite coffee shop owner, it's a race against time before Charlotte's rep is permanently canceled. Can Coco uncover another killer, or will Charlotte go from barista to behind bars?
