Madeline was at the beach again one night, when she saw a flashlight on her. Madeline heard voices and saw shapes of two men. One of the men called her out and flashed her with the flashlight. The man told her to halt and asked her who she was and where she lived. She knew that this was not good. The men told her that they were the Coast Guard, but she hear foreign voices. She knew something was fishy. The next few days, she kept seeing someone around their boarding house. They looked suspicious. Madeline was out riding her bike, when someone in a car ran her off of the rode. She knew it had to be them. She had to tell someone so she told Johnny. Madeline and Johnny went the next day to find any clues they thought could lead to suspicion. They both found German cigarettes. They also came across some of the Nazi's stuff. Those people had been Germans. Madeline and Johnny called the FBI and remained anonymous, but they saved people from getting hurt and they got to the end of that mystery.
