Logan is shocked to learn about the murder of Mrs. Donaldson, the older lady who previously owned the home he and his family just bought. Though it was creepy that someone had been killed in his home, Logan's family assured him that it was in the past - a random murder/robbery that went wrong.
Logan's new neighbor Arthur thought otherwise. After researching the cold case, both boys are convinced that Mrs. Donaldson was targeted. She had been accused of embezzling money from Magic Forest - the town's closed amusement park. Many people felt like the real reason the old lady was murdered was because she simply knew too much - knew who really had stolen the money - and the killer found a way to keep her permanently quiet.
