"Valentine's Day is around the corner and a note shows up in the Help Box from Officer Gill. He asks the three friends to keep an eye on the creepy ivy-covered corner house. But it isn't just the house that's creepy. A woman lives there, but she's hardly ever home. And when she is, she rarely comes outside. Will the Calendar Club finally come face-to-face with their mysterious neighbor? Maybe not, as an even more mysterious woman appears at the house-- a movie star who collects strange cupid statues!"--Page 4 of cover
