First, I should check if these authors are known for a particular style. Lana C might be a pen name for Laura Carlin, but I'm not sure. Saskia's last name is just given here, but maybe it refers to her contribution. Since it's a mystery, elements like suspense, clever puzzles, and maybe a small-town setting are common in such stories. I should structure the review to include an overview, setting, characters, plot, strengths, weaknesses, and a conclusion.
