Suzanna knows what happened in the midnight tunnel, so why won’t anyone believe her? Suzanna “Zanna” Snow has sleuthing in her blood.

With the famous Bostonian detective, Bruce Snow, as her uncle, she knows she has more than just a pinch of investigative talent. But nothing out of the ordinary ever happens in the sleepy coastal town of Loch Harbor, New Brunswick. Instead of sharpening her detective skills, she’s stuck serving tea and learning how to be a “proper lady” at the Rosemount, an exclusive summer hotel under her parents’ impeccable management.

Everything changes one night during a thunderstorm, when one of the hotel guests, a young girl, goes missing. Zanna is certain she has clues that lead tothe girl, but only her friends, Lucy and Isaac, believe her. When detective Bruce Snow is called in, Zanna sees her chance to help solve the case. But everything is not what it seems, and as the mystery thickens, Zanna begins to suspect another crime is unfolding. And if her instincts prove correct, she’s sleuthed her way into a grave amount of danger.
