A sign outside the old Remmington Mansion read, “This Property is Condemned.” Sam Cooper couldn’t figure out exactly what that meant. Even after his father explained it, he became more puzzled than ever. So, along with his friends, Tony and Tyler, he set out to solve the mystery. Sam thought the old place was abandoned. But, when the boys went to investigate, a curtain moved, and they discovered old Mrs. Remmington still lived in the crumbling house. Sam was the kind of person who would try to right any wrong or help anyone who was in trouble. And Mrs. Remmington was in a lot of it. So, he organized the whole town to go out and fix the place up like new. But that’s when his problems really began. Why did those men try to scare the old woman into moving? And, why were they threatening Sam and his friends? No matter what it took, Sam was determined to find out.
