Whispers in the Graveyard — Max Elliot Anderson

Josh didn't like moving from his safe, comfortable house into a cramped apartment in Chicago. His father had taken a new job and the family hadn't found the right house yet. But Josh made friends with Kim, Mason, and Dexter. The four boys did everything together. Dexter's father was a funeral director. The boys' biggest problem was that the quickest way to the subway was straight through the center of the biggest cemetery Josh had ever seen. The place was locked at night, but the boys knew how to get in. The only thing was, who'd want to? One night, as the boys returned home after dark, a gang began chasing them. Josh and his friends had no choice but to duck into the cemetery. They thought the gang was scary, but that was nothing compared to what they saw and heard next. The boys set out to unravel the mystery behind why those awful men were digging in the cemetery at night. What they discovered was a gigantic drug smuggling ring, and the boys found themselves right in the middle of it. Now if only the police can get there in time.
